I think traveling 280 million mile round trip in a tractless, airles, freezing, boiling hot, void full of micro meteors, cosmic rays flashing in ones eyes while trying to sleep, the confinement, mechanical breakdowns, CME's, boredom, and loneliness, might have something to do with it.
Imagine a 50 trillion mile return trip to alpha Centauri. Advanced robotic construction, extension of human lifespan by genetic engineering, sustained thermonuclear fusion rockets and space based ultra powerful lasers are all prerequisites plus the ability to create artificial biospheres. The nearest Close Earth Analog Planet may be much further. I am not optimistic about Proxima b. There may be better planets around Alpha Centauri A and B.
@@johngeier8692 none of it matters all that Star Wars stuff is just science fiction fantasy. In 100,000 years if humans still exist we still probably won’t be able to travel across the galaxy 🌌
What was not mentioned was that on Mars, a person weighs about 1/3 what they weigh on Earth and that Mars has no magnetic field, so the radiation and gravity problems would last the entire mission. Getting machines to Mars is difficult, but has been done several times, Getting people to Mars and back(and have them survive) is extremely difficult. End of the century is optimistic.
The surface gravity on Mars is likely much better than zero. Keeping astronauts supplied with food, water and oxygen is the big problem. Life support modules will need to be sent in advance of the manned crew who will land nearby. I cannot envisage anymore than a small research base on Mars in the near future.
And also the fact that plants would need to be transported (somehow), for oxygen to be produced for breathing, and then there is the matter of food production and WATER!
@@johngeier8692 It is 38 percent that of Earth. We have known this for a long time. What we do not know is whether that is enough surface gravity for human physiology to work properly.
It’s my opinion that we have a very long time if ever to Reach the planet Mars & at best several hundreds years just to begin to colonize Mars successfully! The variables known & unknown are beyond mankind’s ability to comprehend today!
I think we should "practise" base building on the moon first and see how we do a year out there. Can also imagine that moonbase to be a "basecamp" to travel to Mars from.
The moon is the best bet first I'd say. Much closer if anything goes wrong, and easier to transport supplies to, and we'll be able to see how well (or bad) the human body can adapt to the lower gravity. Maybe the occupants can use mini O'Neill cylinders twice a day for exercise.
Distance and the thin atmosphere makes landing a challenge.I don't hold out much hope of human visitors in the next hundred years or more.Besides what's there exactly?it can sustain a population and would be totally reliant on supplies from Earth.
We can do it. The real question is, what will the trip accomplish? There’s nothing there. For now, sending probes to study the planet has been helpful. Sending people is cool…but…not sure about the risk vs reward. I say let’s do it, but make the mission worthwhile. Don’t just go to say we went there.
Thats the problem, no matter how efficiently we can get there, it's going to be too expensive to attempt unless there's a good enough reason to actually do it.
@@sonicdoesfrontflips I agree. I’m excited at the idea, but it kind of seems like a waste. We can study the planet with probes. What will humans there do that probes can’t? We should go if we want to start building a settlement. But just to take some selfies? Just seems wasteful. It’s like taking a trip across the country so that you can tell your friends that you did it.
@@mastermindrational1907 selfies are as good a reason as any, If those selfies inspire the next generation to try and one up them, then money and time well spent.
@@mastermindrational1907 My arguement to this is that, there is something about the human eye and sensory experience that will tell us and teach us more about the planet then probes or robots can, even as advanced as they are. I think people can make greater assessments of the things they see and can touch rather than trying to triage data points from cross-analyses of martian soil can.
@@xcryosonx I just want the trip to be productive. It seems we are doing it to say we can do it, and I suppose that in itself has some value to humanity. Maybe it will inspire more space travel innovation, which is something we need to improve on. The final frontier will require an endless effort at developing faster and faster space travel capabilities.
This video just scratches the surface of the difficulties involved. However, it's refreshing to see one that doesn't completely dismiss the enormous challenge of it. Good job!
False, haven't watched the video but it's about 55 million miles away, the moon for reference is about 240k miles away and still a real challenge. Definitely more challenging to find a way to travel to Mars and back but 55 million mile journey is still not possible atm.
I disagree, it is hard to get there, it's extremely hard to keep people alive, and for now, impossible to get them back. However, since the astronauts will surely die either en route or on the surface, getting them back won't be a priority.
Some of those problems can be solved by simply sending more than one ship. For instance sending 15-20 unmanned supply ships over 5-10 years before you ever send people.
I did not understand the end of the video asking about the Moon, I thought this was about Mars. I do believe we will need more advanced robotic missions designed to set up and test logistics for manned missions to succeed. Take as many decades as needed and do it right.
The moon is essentially a stepping stone to Mars. There's a location ~2/3 to the moon (between Earth and th emoon) called the LaGrange point. If you launch your mission from there - where the gravity well is at its lowest, you can conserve propellant/energy, i.e. use a lot less propellant (see my comment above), or carry more cargo.
Hahahahahahaha 😁 he is right. Humans can not travel to the moon at this time due to the issue of life threatening radiation which is of cause not an easy to overcome as he pointed out in the video
If something goes wrong like in the Apollo mission you have to wait 20 minutes until you get a response so you’d need biggest balls of steel to even think about travelling there.
If something went wrong on Columbus's mission, he'd have had to wait years for someone to go see what happened to him. Don't worry. Volunteers will be standing in line for the opportunity to go. Maybe carbon fiber balls.
This description I found amazing for perspective: It was said that when Redbull and Felix Baumgartner did his famous free fall back to Earth from a platform lifted by a helium balloon... the distance above Earth that was could be accurately compared to placing a quarter on a physical globe map of average size.
Comments/corrections: 1) 0:11 SpaceX is not a space agency 2) 1:36 The Tiangong space station isn't "in China". 3) 2:06 It's not referred to as L-E-O. It's pronounced Leo (like the name). 4) 7:15 to 8:00 It's not referred to as just fuel. It's called "propellant" since "propellant = fuel + oxidiser". You need to carry the oxidiser to burn the fuel. 5) 7:39 See 4) although the oxidiser can be either CO2 from Martian atmosphere *or* oxygen from Martian polar ice. 6) 8:12 This would be true if the space shuttle hadn't been retired ~a decade ago.
To travel to Mars and the other planets we need to invest in nuclear powered engines. Just as our modern submarines operate on nuclear power for deep ocean journeys the same must be adapted for long space missions. A nuclear powered engine may also cut travel time to Mars and back.
Do you even know how nuclear power works? The uranium heats up water to produce steam, the steam then turns an electric generator to produce electricity. How the hell will this propel a spacecraft??
@@Coolcarting I wasn’t talking about steam but nuclear power fuel that NASA has been looking into. I believe one problem is solving the issue of overheating in the exhaust system. I also know ion power is also being explored as a possible alternative to chemical rockets.
@@xeon4044 "The AEC, SNPO, and NASA considered NERVA to be a highly successful program in that it met or exceeded its program goals. NERVA demonstrated that nuclear thermal rocket engines were a feasible and reliable tool for space exploration, and at the end of 1968 SNPO deemed that the latest NERVA engine, the XE, met the requirements for a human mission to Mars. It had strong political support from Senators Clinton P. Anderson and Margaret Chase Smith but was cancelled by President Richard Nixon in 1973. Although NERVA engines were built and tested as much as possible with flight-certified components and the engine was deemed ready for integration into a spacecraft, they never flew in space." NERVA had a specific impulse of 841 seconds in vacuum and 721 at sea level. The SpaceX Raptor's is 363 s and 327 s respectively and the Saturn V's Rocketdyne F1s were 304 s & 269 s respectively, so it's way more efficient and this was 60s tech. Without at least nuclear thermal propulsion Mars is out of reach to human exploration. Search YT for "NASA Project ROVER NERVA Nuclear Rocket Engine testing @ Jackass Flats"
NERVA seems like a huge advancement in rocket propulsion (2 x's the thrust). But how do they solve the risk of a launch failure while getting the nuclear fuel into space? It seems that the risk of polluting the biosphere with a high-altitude, widespread dispersion of highly toxic fuel is simply too high.
As robots become more and more sophisticated, the practical, logical reasons for sending humans to Mars will become less and less compelling. All that will be left is emotional reasons. Given the expenses involved, i think there's a real chance it won't happen, potentially ever but certainly not for many decades
When I was young and growing up in rural Oregon in the 50's, I did a lot of hitchiking. So, the main reason why it's so tough to get to Mars is there isn't a lot of vehicles slready going there which one can thumb a ride with. Of course, if you already have our own Tom Corbett space suit with you, then that makes it a lot easier.
Humanity has always obsessed about challenges: crossing vast oceans, climbing the highest mountains, exploring the densest jungles, etc. It is “in our DNA” it appears, to seek out the next daunting mission or venture or challenge. In the 1960’s it was the Moon. Now-? Mars, it seems. It will be accomplished SOMEDAY. At great cost; as all the steepest challenges have cost us: in money and resources and human life itself. Why must we do these things? Because we are human.
Getting humans on Mars will be super cool, no doubt about that. However, beyond the "we did it" factor, it's kind of pointless. There is nothing there for us, really, except exploration and science. We can already do pretty much all this with our robots.
Wrong. Imagine if our ancestors in the 15th-16th centuries had the same mentality as you. « Lets not go across the ocean, its useless theres nothing there its a waste » maaaa maaaa (baby crying) Lol if only they knew that colony 300 years later would come back, as a stronger nation, to save their asses.( WW2) You dont know what you need until you discover it.
It is logical from safety PoV. But, look at the population, its 8 Bil already, and growing. Where will all these people go? Maybe to moon, then Mars, but yes. We have to expand.
@@frankauc6023 problem is if you say strained on Americas you could still survive and wait for rescue from some random ship. Or just live on. Meanwhile in Mars you will be dead in minutes if anything goes wrong And the rescue would take atleast 9 months to come.
Incorrect. Setting up a future base on mars and starting a settlement ensures the human race prolonges itself. Its an investment. Extinction on Earth is inevitble, whether that is by our own doing or a catastrophe that is out of our control.
I always wondered why they couldn't use magnetism on board to assist with emulating gravity. It wouldn't help your blood flow, organs, etc, but it would keep your muscles from decaying.
That is very interesting. Maybe magnetism would help blood flow with a high iron diet. I'm no genius but you brought up a very interesting point. Forced hibernation may be the only way to stave off insanity.....There is a lot to think about, and it's fun to think about.
the weight has to be applyed down the whole body so maybe with straps but I say we do build a centerfgal area that simulates gravity and slowly deceases as it apporches Mars and intensifes as the come back towards Earth.
@@XxxXxx-fm3wo Yeah like a magnet floor with a metal suit, or even viceversa with magnetized cuffs and straps since the entire ship is metal. The only problem with that would be that you'd get stuck to everything if you weren't careful.
Surely, the first steps have to be staged. A moon base where supplies can be sent. Is it not easier to launch a Mars mission from the moon? Really interesting subject, great channel. Thank you.
I think it’s a huge psychological physiological and mechanical challenge. They would have to send hundreds of tons of supplies a head of time to Mars. Then, would the astronauts be mechanically inclined to build a habitat to live in ? And furthermore rocket technology is obsolete for long distance. Space travel. We need a different type of propulsion to get us to vast distances in space.
Absence of real-time communication from Mars and the fact that human bodies don't react well to weightlessness, makes it seem irrelevant to me. Learning to live on Earth as a species is a much more important process that doesn't get the attention it deserves.
The problems are big, but not too big. IMO The first thing is to realize you will need to send multiple ships into Mars orbit with fuel and spare parts for the return trip. We may need to send the descent stage as one of those vehicles. This will all have to be in place before the manned mission takes off. That vehicle will need specialist who know the ship inside and out. Can make any repairs without fail. You will need navigators that can get to Mars possibly without communications with earth. The ship will have to be strong enough to prevent micro meteorites and radiation from harming the crew. These ships will be massive. I will not see it in my lifetime. If we would have kept Apollo going, then maybe we would be close now. Just thinking out loud.
One cannot compare1960 technology with 2020 plus technology, ie foodstuffs, fuel etc. I can understand making these comparisons, but they need to be re-assessed to make something believable. Its still a very, very long way.
Sorry but the The F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.[1] unless nuclear rocket engine gets invented, it isn't that much difference
Hear me out we need to put a fueling station in orbit. And a modification station in orbit. Launch rocket. Then freshly refule in space. Take on extra load and mass at modification station. Send a fresh rocked filled with everything from orbit takes less power to get going. Also have a supply station. That we take time to supply. And send a additional 10 rockets all filled with everything we need to get started when we go. I'm no engineer but I feel like that is the best way to do it
I think, feel, and believe anything is possible. However, going to Mars is a monumental distance and travel, with many considerations. From the video, some of these issues are being resolved based on what our brightest Earthlings have been able to contemplate. So, we are already in the phase of understanding the many challenges in identifying, understanding and then, overcoming them one at a time for a safe and well-planned exploration to Mars. It will take time as we have already landed a robotic type of vehicle on Mars and learning, even applying that learning going forward into the future.
Firstly, we need to concentrate our efforts into making a faster space vehicle. That alone will solve/reduce quite a lot of the other problems of getting there. As I understand it, we have the knowledge, or at least most of it, to make a space vehicle that will cut the journey time considerably. We just have to make it. Come on Elon and NASA!
It is so difficult to get to Mars Because we never made a functional "Space ship" because we can't, yet. The Shuttle was only a taxi to orbit and could not go anywhere else. A few orbits and that's it. It was an "Orbiter" and can only go 'round and 'round just like a bus but a little higher and faster. Until we conquer gravity, we are stuck for the most part.
It’s most likely that we will spend many years on the moon as a precursor to Mars travel. The weakest link in this chain is the ability to keep humans sane, wealthy and safe during the entire mission.
Some of this information is out of date, The Saturn V no longer holds the record for most powerful rocket as the Artemis SLS system that just went to the moon is 15% more powerful.
@@CaliSteve169 I assume if someone had told you, 2 centuries ago that we can invent an object capable of transportation by Air. Pretty sure ur response would b ... "you sound deranged Mate"
@@CaliSteve169 uhm.. I think it has everything to do with the topic. Cus he 👆 said it wont b hard in 500 years, ofcourse we all aware technology would be more advanced nd better, enhancing d prospect of space traveling. Well for now.. we all sound deranged *
I think if they could find a way to harness the energy of the sun per proportion, I think they could do it. The sun has Indus amounts of energy. How that would work I’m not sure, but it would be a steady supply of energy as far as the astronauts go they would have to go through psychological and metal training to be able to handle such a trip. Because it would be very stressful. There’s a lot that they need to work on maybe way down the road they will figure this all out
Nice that you mentioned the massive problem people often don't mention - the interplanetary radiation. Although the Sun feels like a nice, warm and comforting friend when strange outside on a summer's day, it is actually a gigantic unshielded nuclear reactor 100m times the mass of Earth, blasting out radiation on a level our brains can barely comprehend. Earth's magnetic field keeps us nice and protected down here. But despite best paths through that van Allen belt, the astronauts on the Apollo missions received what would today be unacceptable levels of radiation exposure. But the moon is very close, and those levels pale in comparison to the space between Mars and Earth. We currently don't have any way to protect astronauts on this mission that would be mobile enough to get there. They would not be in a fit state to explore Mars when they got there. And that doesn't even take into account the rest of the logistical problems, even if we created a super efficient drive that didn't require a silly asking of fuel, as it would with current technology. We just don't have the technology to do it. I always hoped I'd see it. I still hope I do. And even if it's arrival is at 3am on a work night, I'll be there watching ans see it live (or 10 minutes later, at least), as I was when New Horizons got to Pluto in the middle of the night. But I don't think we're there yet, or anywhere near, really. Likewise, if I live to see it, my kids have orders to prop my senile body up to watch a probe send telemetry back from the Centauri system. But I'm not hopefull for that, either. I do hope I live long enough to see a probe confirm microbial life elsewhere in the solar system. That's probably more likely, really. But who knows. Technological advances cannot be predicted, so here's hoping I cheer on astronauts as someone has to better that immortal line, "one small step for man, one giant leep for mankind." Or even better, see an actual photo and analysis of a planet in Proxima.
I just realised now that real time communications is not possible with other planets. That's a big issue and means you cannot depend on earth while you are out there, and it has serious implications for colonizing Mars as the people there will have to be much more independent.
Yes there are formidable problems and hurdles to this undertaking. Some notes On the space station, various exercise machines that the astronauts use help simulate gravity, eg rubber straps holding them down while they run on a treadmill. This slows down the bone deterioration and keeps them fit They will not be weightless for their months on Mars, and will have to walk in heavy space suits outside their habitation One idea for the radiation is to have cylindrical water tanks around the living space of the capsule to reduce space radiation. As water is consumed it can be replaced by waste water etc It may be necessary to have robots build a concrete type landing pad for the first crewed mission, esp if they are going to use the Spacex Starship which is very tall. It has to land on a hard flat surface. Even landing robotic probes on Mars has proven extremely problematic. They will need probably fuel tanker supply ships to refuel after reaching high earth orbit, after accelerating to the voyage speed on the leg out, After landing, and after regaining Mars orbit for the return journey. So thats a lot of lauches right there. I am not sure how they can keep the liquid oxygen cold and contained for so long. Keeping it at minus 220 C for so long will be difficult. Although they talk about turning the Mars water into rocket fuel via electrolysis, this water is mostly in the poles, which is not where they could survive, being so extremely cold. It would be best if there is a habitable soil/concrete covered dome for them to live in, already constructed before they land, due to the high level of radiation on the Martian surface as well. This means sending constrction robots to do this somehow before they go. There are plans for how to build these domes These are just a few of the logistical problems for a successful mission. Im not convinced it is worth it. I am sure that it would be scientifically wonderful, but that living there long term is impossible due to Mars being extremely cold, almost devoid of atmosphere, and has lots of harsh abrasive sticky dust (which was also a big problem on the moon). And again the radiation issue
We may be years or decades from inter-planet travel, but I believe that we humans are meant to do that. Maybe in next 500 years, after many wars and pandemics. But we will populate many planets one day, just like we populated every continent on Earth.
@@CaliSteve169 I have seen planets with my own telescope, their moons as well. I know the telescope that I have is not showing as good view as the ones with NASA & other space agencies, but it does show those colors of Mars, venus and Mercury, jupiter etc as they are. So its not all a lie. Nautical Almanac is a book which can tell u exactly at what time there will be moonrise, sunrise, age of moon, position of planets etc. So it shows that what space scientists are telling us has some worth in it. And just like a doctor doing heart or brain surgery, we should trust them.
@@Daw00d227 I have a telescope and I have seen the as well. However you've no way of telling what they are, how far they are etc. Centuries ago, authorities would tell people that those are gods, goddesses etc. Now they tell us those are earths located insanely far away and we send remote controlled buggies there. All bs if you ask me.
I love your videos, but the audio from the clips sometimes drowns out the voice over. Especially on AppleTV. You guys should work on your volume leveling.
What might be possible is a trip to Mars and back without landing and with 2 to 4 astronauts, similar to the Apollo 8 mission to the Moon in 1968. We would learn a lot about the effects of weightlessness over several months. Also, I believe we may yet discover a way to fly faster in space and so cut down the time of the journey.
In my book The direction of Man I show that in the future we will develop robots that will be as capable as humans to do the planet exploration similar to Data in Star Trek.
Mars has. Little to no atmosphere, soo all that radiation gets in from the Sun. Radiation makes it next to impossible for humans to survive under those conditions
One thing I still want to know is how we are gonna slow down. You cant just fire your engines the entire way there, space is a vacuum, theres no way to slow down. You'd have to flip the entire craft around at the half way mark and burn the engines the opposite direction. Or could you get in an orbit and then send down like a lander? But a lander wouldnt have the equipment we'd need. The entire craft would have to be able to land, and I havent read how that can be possible yet.
Landing the entire craft would not be a good idea, as you'd have to carry all that fuel to be able to get back to Earth. Better to have a separate landing capsule, as we did on the moon. Leave the "command module" in orbit, possibly staffed by 1-2 astronauts.
So many things can go wrong. One would be the mind. How would the mind handle the stresses of being on a highly difficult mission in deep space for months? Knowing that every possible scenario has to go right just to reach Mars. One thing that goes wrong would be death
None of us reading my comment at this time will be alive to witness human on mars. Besides we'd be better off trying to make sahara green instead of spending trillions just to go to another big desert.
If countries come together with a focus to make Mars a priority we definitely could make great progress within a century. They need to build supply stations 1st. They need to develop building larger stations. They have to build more sturdy vessels for sure that are more efficient on fuel. Stay should practicing by doing manned missions to Venus 1st. Considering Venus is closer. Edit: I know the surface of Venus is another level of challenging. I simply meant to practice round trips of manned missions to a closer planet not necessarily to land on it,... yet.
@@amithmalik4648 The same argument was made when settling the new world. The same argument was used when covered wagons rolled west. The same argument was used concerning the Apollo missions.. AND the direct use of the Apollo moon missions was absolutely every computer, Apple, Microsoft,, When an infant is born there is no way of knowing if he or she is the next Einstein. On the surface,, I tend to agree with you. I just feel there must be room for both.
At least you're smart enough to tell the difference between "spaceflight" and "manned spaceflight". Which makes you a midwit. We go into space to get the tech to fix things when they go wrong immediately after they go wrong. The Hubble Telescope for instance needed to be fixed by humans. Later we will want to bring platinum to Earth - you know, the catalyst, which makes our cars clean. Or we will want to bring other rare metals which make up our batteries to stop global-warming. I too don't want Mars. I want Psyche, Deimos, and the Moon. Beltalowda!
Many people think that our future as species is beyond our home planet. But setting foot to another planet that is quite inhospitable and Geo-morphizing it just to make it bearable for humans, is so hard, that I still wonder why don't they just put all this effort and resources to save this beautiful planet we already have, which sustain us, without us putting so much effort. Whoever believes that Mars is the first step to the solution, has not posed the correct question in the first place.
I can't see ever being able to travel to any other planet outside our solar system. The nearest star is Proxima Centauri and that would take thousands of years to reach. So we must take care of this world.
And yet despite everything stated here, the Mars One operation originally expected to have already set a one way mission of humans to Mars several years ago which obviously was a pipe dream all along. I think humans going to Mars is still many decades away and may prove to be impossible unless a much faster speed of transport is developed along with a way to limit weightlessness. Overcoming the reality that the human body is designed for earth is probably not realistic. Makes much more sense to focus on sending probes with greater abilities as the technology develops while focusing on a permanent human base on the moon first.
I don't think getting to Mars is difficult. IT'S IMPOSSIBLE. We would have colonized the Moon by now if manned space flight were doable. We're told we went there 50 years ago yet no effort has been made to establish a colony there. That makes me suspicious of the whole idea of MSF. It has always been a dream to do this. Yet 50 years after Apollo it's still a dream. Mars? They've been planning a Mars mission since I was born. I'm 80. Still, Elon might prove me wrong, it's only a layman's opinion. Good luck with that.
I remember watching space docs in the 90s as a kid thinking they’ll surely make it to Mars within 20yrs. Here we are 20+yrs later still no progress whatsoever. If they really wanted to do it they could easily but war and politics is never ending, holding us back as always.
War actually *helps* rocket-science. Look at Wernher von Braun. Politics, yeah, hurts. Especially peacetime politics. Peacetime politics turn science into jerbs. This is why the SLS cost too much, and the Shuttle before it.
We need to construct a purpose built interplanetary spacecraft in orbit capable of a round trip to Mars that is self-contained instead of faffing around with 1960s technology. A ship that is comfortable enough for six crew members and perhaps find a way to rotate the spacecraft to produce artificial gravity because having watched this video ,which is excellent, it's clear we don't have the technology for a 2.5 year extended stay on Mars at present.
No, not with the current technology we have available to us. To use an analogy, the current space ships we have is like the sailing ships, galleons of yesteryear which took months to reach their destinations.
What? That's some thinly veiled flat earth nonsense right there. There have been plenty of pictures of the earth taken. The first astronauts in the 60s used modified Kodac cameras to take pictures of the earth from the viewport in thier rockets. They did the same from the moon. Skip to modern day you have satellite imagery, pictures taken from SpaceX, pictures taken from the ISS. If by CGI you mean digital, then the same can be said for you. All photos taken in modern times are digital reconstructions, does that mean you're flat? I mean your brain might be, but the rest of it is as you appear in reality.
We need a faster mode of transport with less fuel use, solve the gravity issue in space, radiation protection, how to make oxygen, different type of fuel (nuclear), where will they get water, how do you grow food? Solve these problems & we travel wherever
The Crew don’t have to experience weightlessness though because Mars unlike Space has Gravity after landing 🛬, so technically they can walk outside the Spaceship.
I tried it. Google maps has no route. I went outside and couldn't even see it. Then I tried to run in the approximate direction and failed. It *is* really hard.
Let me get this straight. We sent man to the moon not even 50 years after the very first flight! Here we are 50+ years after that, and we can’t go to Mars??? Ridiculous! Let’s GO!!!
Thankyou again for another FINE video! I think Mars will be a go reasonably soon, at least in the lifetime of Elon Musk. He certainly seems motivated to make it happen. I believe if he didn't continue his ambitions in that direction then it probably won't happen for a long, long time. Cya Space Cadets! 🇦🇺🤗
We should just call them all “astronauts” for consistency, not use words like “cosmonauts”, “taikonauts”, etc. unless you’re speaking a foreign language.
Place space stations all along the route to Mars. Then we could leap frog to Mars comfortably and less risky having fuel supplies and comfort for crew.
Uh… You realize it isn’t just a fixed straight line between earth and Mars, right? Both orbit at different speeds with very different orbital circumferences, so sometimes the earth and Mars are on completely opposite sides of the sun from each other… Your idea is honestly wack

You sure about that?

@@victorfinberg8595 The New American frontier
What was not mentioned was that on Mars, a person weighs about 1/3 what they weigh on Earth and that Mars has no magnetic field, so the radiation and gravity problems would last the entire mission. Getting machines to Mars is difficult, but has been done several times, Getting people to Mars and back(and have them survive) is extremely difficult. End of the century is optimistic.
The surface gravity on Mars is likely much better than zero.
Keeping astronauts supplied with food, water and oxygen is the big problem. Life support modules will need to be sent in advance of the manned crew who will land nearby. I cannot envisage anymore than a small research base on Mars in the near future.
@@johngeier8692 Radiation is also a worry. Mars has no magnetic field.
And also the fact that plants would need to be transported (somehow), for oxygen to be produced for breathing, and then there is the matter of food production and WATER!
@@johngeier8692 It is 38 percent that of Earth. We have known this for a long time. What we do not know is whether that is enough surface gravity for human physiology to work properly.
We went from horse and buggies to the moon in 60 years. I'm sure end of the century is way more than reasonable.
It’s my opinion that we have a very long time if ever to Reach the planet Mars & at best several hundreds years just to begin to colonize Mars successfully! The variables known & unknown are beyond mankind’s ability to comprehend today!
I think we should "practise" base building on the moon first and see how we do a year out there. Can also imagine that moonbase to be a "basecamp" to travel to Mars from.
The moon is the best bet first I'd say. Much closer if anything goes wrong, and easier to transport supplies to, and we'll be able to see how well (or bad) the human body can adapt to the lower gravity. Maybe the occupants can use mini O'Neill cylinders twice a day for exercise.
Just highlights the importance of caring for THIS planet - there is simply NO alternative!
Actually staying on Earth isnt an option, the Sun will eventually expand.
Let’s be honest, robots are far better equipped for space exploration than us fragile humans
That's true!!!
Distance and the thin atmosphere makes landing a challenge.I don't hold out much hope of human visitors in the next hundred years or more.Besides what's there exactly?it can sustain a population and would be totally reliant on supplies from Earth.
Very informative and not boring. Great job on the video
We can do it. The real question is, what will the trip accomplish? There’s nothing there. For now, sending probes to study the planet has been helpful. Sending people is cool…but…not sure about the risk vs reward. I say let’s do it, but make the mission worthwhile. Don’t just go to say we went there.
Thats the problem, no matter how efficiently we can get there, it's going to be too expensive to attempt unless there's a good enough reason to actually do it.
@@sonicdoesfrontflips I agree. I’m excited at the idea, but it kind of seems like a waste. We can study the planet with probes. What will humans there do that probes can’t? We should go if we want to start building a settlement. But just to take some selfies? Just seems wasteful. It’s like taking a trip across the country so that you can tell your friends that you did it.
@@mastermindrational1907 selfies are as good a reason as any, If those selfies inspire the next generation to try and one up them, then money and time well spent.
@@mastermindrational1907 My arguement to this is that, there is something about the human eye and sensory experience that will tell us and teach us more about the planet then probes or robots can, even as advanced as they are. I think people can make greater assessments of the things they see and can touch rather than trying to triage data points from cross-analyses of martian soil can.
@@xcryosonx I just want the trip to be productive. It seems we are doing it to say we can do it, and I suppose that in itself has some value to humanity. Maybe it will inspire more space travel innovation, which is something we need to improve on. The final frontier will require an endless effort at developing faster and faster space travel capabilities.
This video just scratches the surface of the difficulties involved. However, it's refreshing to see one that doesn't completely dismiss the enormous challenge of it. Good job!
It's not hard to get there, it's hard to get back.
False, haven't watched the video but it's about 55 million miles away, the moon for reference is about 240k miles away and still a real challenge. Definitely more challenging to find a way to travel to Mars and back but 55 million mile journey is still not possible atm.
Thanks Elon. Any other stupid revelations for us?
You can't leave earth. Stop believing cartoons.
@@CaliSteve169 They're not ready for that yet. Go easy on them, Steve.
I disagree, it is hard to get there, it's extremely hard to keep people alive, and for now, impossible to get them back. However, since the astronauts will surely die either en route or on the surface, getting them back won't be a priority.
Some of those problems can be solved by simply sending more than one ship. For instance sending 15-20 unmanned supply ships over 5-10 years before you ever send people.
Oh yeah sounds easy 🤣🤣🤣🤣🤣🤣
@BridgeStamford simple not easy.
You’d have to land the people close enough to the supply ships, or they could not access them. That could be very difficult.
I did not understand the end of the video asking about the Moon, I thought this was about Mars. I do believe we will need more advanced robotic missions designed to set up and test logistics for manned missions to succeed. Take as many decades as needed and do it right.
I think he simply misspoke and meant mars.
Misspoke …and also typed it incorrectly? Strange
The moon is essentially a stepping stone to Mars. There's a location ~2/3 to the moon (between Earth and th emoon) called the LaGrange point. If you launch your mission from there - where the gravity well is at its lowest, you can conserve propellant/energy, i.e. use a lot less propellant (see my comment above), or carry more cargo.
Yeah what a blunder.
Hahahahahahaha 😁 he is right. Humans can not travel to the moon at this time due to the issue of life threatening radiation which is of cause not an easy to overcome as he pointed out in the video
Distance is a big factor without a doubt.
Let's do the Moon.
You think so, Einstein?
@@mikelarry2602 we are going to put a moon base on the moon but human can't live there permanently
🤣
If something goes wrong like in the Apollo mission you have to wait 20 minutes until you get a response so you’d need biggest balls of steel to even think about travelling there.
Big Balls of steel will be too heavy for the ship 😂
If something went wrong on Columbus's mission, he'd have had to wait years for someone to go see what happened to him. Don't worry. Volunteers will be standing in line for the opportunity to go. Maybe carbon fiber balls.
That's also assuming they have an answer immediately lol
And a steel scrotum would make reproducing impossible, so we could not sustain a colony on Mars.

To travel to Mars and the other planets we need to invest in nuclear powered engines. Just as our modern submarines operate on nuclear power for deep ocean journeys the same must be adapted for long space missions. A nuclear powered engine may also cut travel time to Mars and back.
Do you even know how nuclear power works? The uranium heats up water to produce steam, the steam then turns an electric generator to produce electricity. How the hell will this propel a spacecraft??
@@Coolcarting I wasn’t talking about steam but nuclear power fuel that NASA has been looking into. I believe one problem is solving the issue of overheating in the exhaust system. I also know ion power is also being explored as a possible alternative to chemical rockets.
@@xeon4044 "The AEC, SNPO, and NASA considered NERVA to be a highly successful program in that it met or exceeded its program goals. NERVA demonstrated that nuclear thermal rocket engines were a feasible and reliable tool for space exploration, and at the end of 1968 SNPO deemed that the latest NERVA engine, the XE, met the requirements for a human mission to Mars. It had strong political support from Senators Clinton P. Anderson and Margaret Chase Smith but was cancelled by President Richard Nixon in 1973. Although NERVA engines were built and tested as much as possible with flight-certified components and the engine was deemed ready for integration into a spacecraft, they never flew in space."
NERVA had a specific impulse of 841 seconds in vacuum and 721 at sea level. The SpaceX Raptor's is 363 s and 327 s respectively and the Saturn V's Rocketdyne F1s were 304 s & 269 s respectively, so it's way more efficient and this was 60s tech.
Without at least nuclear thermal propulsion Mars is out of reach to human exploration.
Search YT for "NASA Project ROVER NERVA Nuclear Rocket Engine testing @ Jackass Flats"
NERVA seems like a huge advancement in rocket propulsion (2 x's the thrust). But how do they solve the risk of a launch failure while getting the nuclear fuel into space? It seems that the risk of polluting the biosphere with a high-altitude, widespread dispersion of highly toxic fuel is simply too high.
As robots become more and more sophisticated, the practical, logical reasons for sending humans to Mars will become less and less compelling. All that will be left is emotional reasons. Given the expenses involved, i think there's a real chance it won't happen, potentially ever but certainly not for many decades
There are so many variables, so many issues that going to Mars begs the question why and to what end do we hope to achieve
When I was young and growing up in rural Oregon in the 50's, I did a lot of hitchiking. So, the main reason why it's so tough to get to Mars is there isn't a lot of vehicles slready going there which one can thumb a ride with. Of course, if you already have our own Tom Corbett space suit with you, then that makes it a lot easier.
Huge difficult task... Especially mentally once overcame technology problems!
Humanity has always obsessed about challenges: crossing vast oceans, climbing the highest mountains, exploring the densest jungles, etc. It is “in our DNA” it appears, to seek out the next daunting mission or venture or challenge. In the 1960’s it was the Moon. Now-? Mars, it seems. It will be accomplished SOMEDAY. At great cost; as all the steepest challenges have cost us: in money and resources and human life itself. Why must we do these things? Because we are human.
Getting humans on Mars will be super cool, no doubt about that. However, beyond the "we did it" factor, it's kind of pointless. There is nothing there for us, really, except exploration and science. We can already do pretty much all this with our robots.
ALSO OUTSTANDING
Wrong. Imagine if our ancestors in the 15th-16th centuries had the same mentality as you. « Lets not go across the ocean, its useless theres nothing there its a waste » maaaa maaaa (baby crying) Lol if only they knew that colony 300 years later would come back, as a stronger nation, to save their asses.( WW2) You dont know what you need until you discover it.
It is logical from safety PoV. But, look at the population, its 8 Bil already, and growing. Where will all these people go? Maybe to moon, then Mars, but yes. We have to expand.
@@frankauc6023 problem is if you say strained on Americas you could still survive and wait for rescue from some random ship. Or just live on.
Meanwhile in Mars you will be dead in minutes if anything goes wrong
And the rescue would take atleast 9 months to come.
Incorrect. Setting up a future base on mars and starting a settlement ensures the human race prolonges itself. Its an investment. Extinction on Earth is inevitble, whether that is by our own doing or a catastrophe that is out of our control.
I always wondered why they couldn't use magnetism on board to assist with emulating gravity. It wouldn't help your blood flow, organs, etc, but it would keep your muscles from decaying.
That is very interesting. Maybe magnetism would help blood flow with a high iron diet. I'm no genius but you brought up a very interesting point. Forced hibernation may be the only way to stave off insanity.....There is a lot to think about, and it's fun to think about.
the weight has to be applyed down the whole body so maybe with straps but I say we do build a centerfgal area that simulates gravity and slowly deceases as it apporches Mars and intensifes as the come back towards Earth.
@@XxxXxx-fm3wo Yeah like a magnet floor with a metal suit, or even viceversa with magnetized cuffs and straps since the entire ship is metal. The only problem with that would be that you'd get stuck to everything if you weren't careful.
They just need thrust acceleration to simulate gravity like with an advanced ion engine.
That will consume more energy, and add weight.
Surely, the first steps have to be staged.
A moon base where supplies can be sent. Is it not easier to launch a Mars mission from the moon? Really interesting subject, great channel. Thank you.
Talking about Mars...we first must get to the moon in real before dreaming about a trip to the Mars
😅
Because many things: So far away. Radiation. No help if something goes wrong.
I think it’s a huge psychological physiological and mechanical challenge. They would have to send hundreds of tons of supplies a head of time to Mars. Then, would the astronauts be mechanically inclined to build a habitat to live in ? And furthermore rocket technology is obsolete for long distance. Space travel. We need a different type of propulsion to get us to vast distances in space.
Did anyone else notice the globe rotating in the wrong direction?
Do I win a prize?
I'm 70.... if you watch the 1950's movie : " angry red planet", you can see what a journey to mars is like. You can look it up on utube. 👽👽👽
Absence of real-time communication from Mars and the fact that human bodies don't react well to weightlessness, makes it seem irrelevant to me. Learning to live on Earth as a species is a much more important process that doesn't get the attention it deserves.
The problems are big, but not too big. IMO The first thing is to realize you will need to send multiple ships into Mars orbit with fuel and spare parts for the return trip. We may need to send the descent stage as one of those vehicles. This will all have to be in place before the manned mission takes off. That vehicle will need specialist who know the ship inside and out. Can make any repairs without fail. You will need navigators that can get to Mars possibly without communications with earth. The ship will have to be strong enough to prevent micro meteorites and radiation from harming the crew. These ships will be massive. I will not see it in my lifetime. If we would have kept Apollo going, then maybe we would be close now. Just thinking out loud.
One cannot compare1960 technology with 2020 plus technology, ie foodstuffs, fuel etc. I can understand making these comparisons, but they need to be re-assessed to make something believable. Its still a very, very long way.
Sorry but the The F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.[1]
unless nuclear rocket engine gets invented, it isn't that much difference
Hear me out we need to put a fueling station in orbit. And a modification station in orbit. Launch rocket. Then freshly refule in space. Take on extra load and mass at modification station. Send a fresh rocked filled with everything from orbit takes less power to get going. Also have a supply station. That we take time to supply. And send a additional 10 rockets all filled with everything we need to get started when we go. I'm no engineer but I feel like that is the best way to do it
Lol no
only 8 minutes delay when sending a message from mars is insane, that could work
I think, feel, and believe anything is possible. However, going to Mars is a monumental distance and travel, with many considerations. From the video, some of these issues are being resolved based on what our brightest Earthlings have been able to contemplate. So, we are already in the phase of understanding the many challenges in identifying, understanding and then, overcoming them one at a time for a safe and well-planned exploration to Mars. It will take time as we have already landed a robotic type of vehicle on Mars and learning, even applying that learning going forward into the future.
Firstly, we need to concentrate our efforts into making a faster space vehicle. That alone will solve/reduce quite a lot of the other problems of getting there. As I understand it, we have the knowledge, or at least most of it, to make a space vehicle that will cut the journey time considerably. We just have to make it. Come on Elon and NASA!
It is so difficult to get to Mars Because we never made a functional "Space ship" because we can't, yet. The Shuttle was only a taxi to orbit and could not go anywhere else. A few orbits and that's it. It was an "Orbiter" and can only go 'round and 'round just like a bus but a little higher and faster. Until we conquer gravity, we are stuck for the most part.
It’s most likely that we will spend many years on the moon as a precursor to Mars travel. The weakest link in this chain is the ability to keep humans sane, wealthy and safe during the entire mission.
Some of this information is out of date, The Saturn V no longer holds the record for most powerful rocket as the Artemis SLS system that just went to the moon is 15% more powerful.
Actually the Space X Starship is nearly twice as powerful as the Artemis.
It won't be hard in 500 years. We're just ahead of ourselves.

@@imrapheljason space doesn't exist dude. They are milking the taxpayer dry and showing you cartoons. Haven't u figured it out by now?
I think if they could find a way to harness the energy of the sun per proportion, I think they could do it. The sun has Indus amounts of energy. How that would work I’m not sure, but it would be a steady supply of energy as far as the astronauts go they would have to go through psychological and metal training to be able to handle such a trip. Because it would be very stressful. There’s a lot that they need to work on maybe way down the road they will figure this all out
Nice that you mentioned the massive problem people often don't mention - the interplanetary radiation. Although the Sun feels like a nice, warm and comforting friend when strange outside on a summer's day, it is actually a gigantic unshielded nuclear reactor 100m times the mass of Earth, blasting out radiation on a level our brains can barely comprehend. Earth's magnetic field keeps us nice and protected down here. But despite best paths through that van Allen belt, the astronauts on the Apollo missions received what would today be unacceptable levels of radiation exposure. But the moon is very close, and those levels pale in comparison to the space between Mars and Earth. We currently don't have any way to protect astronauts on this mission that would be mobile enough to get there. They would not be in a fit state to explore Mars when they got there. And that doesn't even take into account the rest of the logistical problems, even if we created a super efficient drive that didn't require a silly asking of fuel, as it would with current technology. We just don't have the technology to do it.
I always hoped I'd see it. I still hope I do. And even if it's arrival is at 3am on a work night, I'll be there watching ans see it live (or 10 minutes later, at least), as I was when New Horizons got to Pluto in the middle of the night. But I don't think we're there yet, or anywhere near, really.
Likewise, if I live to see it, my kids have orders to prop my senile body up to watch a probe send telemetry back from the Centauri system. But I'm not hopefull for that, either.
I do hope I live long enough to see a probe confirm microbial life elsewhere in the solar system. That's probably more likely, really. But who knows. Technological advances cannot be predicted, so here's hoping I cheer on astronauts as someone has to better that immortal line, "one small step for man, one giant leep for mankind." Or even better, see an actual photo and analysis of a planet in Proxima.
With Franklin Chang Diaz his"vasimr" drive could get us there in around 40 days, but the radiation problem is still there.
I just realised now that real time communications is not possible with other planets.
That's a big issue and means you cannot depend on earth while you are out there, and it has serious implications for colonizing Mars as the people there will have to be much more independent.
Yes there are formidable problems and hurdles to this undertaking. Some notes
On the space station, various exercise machines that the astronauts use help simulate gravity, eg rubber straps holding them down while they run on a treadmill. This slows down the bone deterioration and keeps them fit
They will not be weightless for their months on Mars, and will have to walk in heavy space suits outside their habitation
One idea for the radiation is to have cylindrical water tanks around the living space of the capsule to reduce space radiation. As water is consumed it can be replaced by waste water etc
It may be necessary to have robots build a concrete type landing pad for the first crewed mission, esp if they are going to use the Spacex Starship which is very tall. It has to land on a hard flat surface. Even landing robotic probes on Mars has proven extremely problematic.
They will need probably fuel tanker supply ships to refuel after reaching high earth orbit, after accelerating to the voyage speed on the leg out, After landing, and after regaining Mars orbit for the return journey. So thats a lot of lauches right there.
I am not sure how they can keep the liquid oxygen cold and contained for so long. Keeping it at minus 220 C for so long will be difficult.
Although they talk about turning the Mars water into rocket fuel via electrolysis, this water is mostly in the poles, which is not where they could survive, being so extremely cold.
It would be best if there is a habitable soil/concrete covered dome for them to live in, already constructed before they land, due to the high level of radiation on the Martian surface as well. This means sending constrction robots to do this somehow before they go. There are plans for how to build these domes
These are just a few of the logistical problems for a successful mission. Im not convinced it is worth it. I am sure that it would be scientifically wonderful, but that living there long term is impossible due to Mars being extremely cold, almost devoid of atmosphere, and has lots of harsh abrasive sticky dust (which was also a big problem on the moon). And again the radiation issue
We may be years or decades from inter-planet travel, but I believe that we humans are meant to do that. Maybe in next 500 years, after many wars and pandemics. But we will populate many planets one day, just like we populated every continent on Earth.

What might be possible is a trip to Mars and back without landing and with 2 to 4 astronauts, similar to the Apollo 8 mission to the Moon in 1968. We would learn a lot about the effects of weightlessness over several months.
Also, I believe we may yet discover a way to fly faster in space and so cut down the time of the journey.
In my book The direction of Man I show that in the future we will develop robots that will be as capable as humans to do the planet exploration similar to Data in Star Trek.
Mars has. Little to no atmosphere, soo all that radiation gets in from the Sun. Radiation makes it next to impossible for humans to survive under those conditions
On the 2nd day after launch to Mars your fellow astronaut plays loud the Macarena again and again. Now what?!
One thing I still want to know is how we are gonna slow down. You cant just fire your engines the entire way there, space is a vacuum, theres no way to slow down. You'd have to flip the entire craft around at the half way mark and burn the engines the opposite direction. Or could you get in an orbit and then send down like a lander? But a lander wouldnt have the equipment we'd need. The entire craft would have to be able to land, and I havent read how that can be possible yet.
Landing the entire craft would not be a good idea, as you'd have to carry all that fuel to be able to get back to Earth. Better to have a separate landing capsule, as we did on the moon. Leave the "command module" in orbit, possibly staffed by 1-2 astronauts.
Sounds like: TOTAL RECALL
So many things can go wrong. One would be the mind. How would the mind handle the stresses of being on a highly difficult mission in deep space for months? Knowing that every possible scenario has to go right just to reach Mars. One thing that goes wrong would be death
None of us reading my comment at this time will be alive to witness human on mars. Besides we'd be better off trying to make sahara green instead of spending trillions just to go to another big desert.
If countries come together with a focus to make Mars a priority we definitely could make great progress within a century. They need to build supply stations 1st. They need to develop building larger stations. They have to build more sturdy vessels for sure that are more efficient on fuel. Stay should practicing by doing manned missions to Venus 1st. Considering Venus is closer. Edit: I know the surface of Venus is another level of challenging. I simply meant to practice round trips of manned missions to a closer planet not necessarily to land on it,... yet.
No where to land on Venus.

Many people think that our future as species is beyond our home planet. But setting foot to another planet that is quite inhospitable and Geo-morphizing it just to make it bearable for humans, is so hard, that I still wonder why don't they just put all this effort and resources to save this beautiful planet we already have, which sustain us, without us putting so much effort. Whoever believes that Mars is the first step to the solution, has not posed the correct question in the first place.
I can't see ever being able to travel to any other planet outside our solar system. The nearest star is Proxima Centauri and that would take thousands of years to reach. So we must take care of this world.
Yes, we can go to Mars, in another life.
The only thing nasa has ever sent to space is your imagination.
Yeah, probably so!!! It's just too risky in this lifetime!!!
And yet despite everything stated here, the Mars One operation originally expected to have already set a one way mission of humans to Mars several years ago which obviously was a pipe dream all along. I think humans going to Mars is still many decades away and may prove to be impossible unless a much faster speed of transport is developed along with a way to limit weightlessness. Overcoming the reality that the human body is designed for earth is probably not realistic. Makes much more sense to focus on sending probes with greater abilities as the technology develops while focusing on a permanent human base on the moon first.
Point, we are not supposed to be no where existing other than where we were put with everything we need, Earth!
No worries! Zefram Cochran is already working on his warp-drive technology
If memory serves me right we are with in 30 years of that invention according to the NG crew.
I don't think getting to Mars is difficult. IT'S IMPOSSIBLE. We would have colonized the Moon by now if manned space flight were doable. We're told we went there 50 years ago yet no effort has been made to establish a colony there. That makes me suspicious of the whole idea of MSF. It has always been a dream to do this. Yet 50 years after Apollo it's still a dream. Mars? They've been planning a Mars mission since I was born. I'm 80. Still, Elon might prove me wrong, it's only a layman's opinion. Good luck with that.
I remember watching space docs in the 90s as a kid thinking they’ll surely make it to Mars within 20yrs.
Here we are 20+yrs later still no progress whatsoever. If they really wanted to do it they could easily but war and politics is never ending, holding us back as always.
They couldn't do it easily. It's very difficult
War actually *helps* rocket-science. Look at Wernher von Braun.
Politics, yeah, hurts. Especially peacetime politics. Peacetime politics turn science into jerbs. This is why the SLS cost too much, and the Shuttle before it.
It's not war and politics holding us back, it's the lack of anything to really gain from sending humans to Mars
If only they found oil on Mars! We’d be there yesterday 😁

Your computer by contrast is powered by the sheer energy of your own wit and gender-studies degree
It's like the farthest you ever ran was a mile, and then you decided to run a marathon.
We need to construct a purpose built interplanetary spacecraft in orbit capable of a round trip to Mars that is self-contained instead of faffing around with 1960s technology. A ship that is comfortable enough for six crew members and perhaps find a way to rotate the spacecraft to produce artificial gravity because having watched this video ,which is excellent, it's clear we don't have the technology for a 2.5 year extended stay on Mars at present.
No, not with the current technology we have available to us. To use an analogy, the current space ships we have is like the sailing ships, galleons of yesteryear which took months to reach their destinations.
There's no such thing as being lost in space, only dead. I would be terrified to make the trip to Mars
With all this new technology we still haven’t gotten a clear photo of Earth. It’s always some CGI
Agreed.
What? That's some thinly veiled flat earth nonsense right there.
There have been plenty of pictures of the earth taken. The first astronauts in the 60s used modified Kodac cameras to take pictures of the earth from the viewport in thier rockets. They did the same from the moon.
Skip to modern day you have satellite imagery, pictures taken from SpaceX, pictures taken from the ISS.
If by CGI you mean digital, then the same can be said for you. All photos taken in modern times are digital reconstructions, does that mean you're flat? I mean your brain might be, but the rest of it is as you appear in reality.
We need a faster mode of transport with less fuel use, solve the gravity issue in space, radiation protection, how to make oxygen, different type of fuel (nuclear), where will they get water, how do you grow food? Solve these problems & we travel wherever
The Crew don’t have to experience weightlessness though because Mars unlike Space has Gravity after landing 🛬, so technically they can walk outside the Spaceship.
I tried it. Google maps has no route. I went outside and couldn't even see it. Then I tried to run in the approximate direction and failed. It *is* really hard.
They need to be one-way trips.
I'm glad it's so difficult to get to Mars because I don't want people on my home
It will going to take a lot longer until we can get there, at least 50+ years
Great video !
❤
Let me get this straight. We sent man to the moon not even 50 years after the very first flight! Here we are 50+ years after that, and we can’t go to Mars??? Ridiculous! Let’s GO!!!
Why is it so difficult to get to Mars? Prob bc I don't want to go over there
Thankyou again for another FINE video!
I think Mars will be a go reasonably soon, at least in the lifetime of Elon Musk. He certainly seems motivated to make it happen. I believe if he didn't continue his ambitions in that direction then it probably won't happen for a long, long time.
Cya Space Cadets! 🇦🇺🤗
Elon is all fluff.
@@kevinskndad63 Hello. Thankyou for your thoughts AND I could not agree with you more! 😁 Cya!
Elon has already figured this out, we just have to give him 400 billion dollars and we'll be there in 5 years. For real this time.
WAKE UP .
Musk should go himself then - he can afford it but does he have the BALLS ???
Me Thinks Not !!!
Why the hell would you want to go there in the first place..?!
Yeah exactly why
Why not.
We should just call them all “astronauts” for consistency, not use words like “cosmonauts”, “taikonauts”, etc. unless you’re speaking a foreign language.
We can’t even go to the moon-
Place space stations all along the route to Mars. Then we could leap frog to Mars comfortably and less risky having fuel supplies and comfort for crew.
Uh… You realize it isn’t just a fixed straight line between earth and Mars, right? Both orbit at different speeds with very different orbital circumferences, so sometimes the earth and Mars are on completely opposite sides of the sun from each other… Your idea is honestly wack
It’s just too far and too much can go wrong
It sure is!!! I wouldn't want to take that risk!!! and what if you make it up there but you might not make it back to Earth safely!!!
Early travellers spent years in ships in search of new destinations, while they could do, why not us.
