Those interior shots of the Soyuz stress me out. So claustrophobic.
6:31 using the space shuttle as your graphic for “space is dangerous” hits hard.
Overall a really great video - a few points though:
1. When showing dracos and superdracos, the video shows superdracos being tested when talking about draco, also it shows a turbopump schematic. Draco and Superdraco are both pressure fed, no turbopump on board Dragon.
2. When explaining the effects of vacuum, Blood inside the body doesn't actually boil. The human skin is sturdy enough to maintain sufficient internal pressure within the tissue to avoid boiling even at 37°C . The issues are instead:
- the bends - excess gas in solution in the blood might form bubbles - causing strokes or other damage - similar to a diver rising too fast.
- freezing - exposed mucous membranes in mouth, on the eyes and inside the lungs will encounter rapid evaporation of liquid, causing drop of temperature and possibly localized freeze burns. This is especially dangerous in the lungs.
- sun burn - if skin is exposed to space directly, unfiltered sunlight will cause severe sun burn due to high UV content and heat where exposed
- suffocation - no air means no oxygen, which causes loss of consciousness after as little as 10 seconds and death within 1-5 minutes
its the very last that is typically deadly. Everything else is harmful but anyone rescued before they suffocated should have survivable injuries.
3. The suit doesn't have to restore sea level pressure. Typically pressure at 10000ft is considered comfortable in airliners, twice as high is survivable, even more if pure oxygen is supplied instead of nitrox, which most emergency suits supply in case of pressure loss. When exposed to vacuum, most IVA suit system typically supply an environment more akin to a climber on the peak of Mt Everest with an oxygen bottle than air at sea level.
4. The mission timeline could have mentioned stage seperation in a bit more detail. During 1st stage flight the g forces slowly increase as there's less and less propellant left. At the end the engines throttle down to prevent it from getting too high, but its pretty intense. Then they shut down at MECO, and you are suddenly weightless for the first time for a few seconds, feeling your stomach and everything else lift, before the 2nd stage ignites for the 2nd half of the ride. Stage sep is quite intense, and so is the 2nd stage flight on Falcon with the engine so close to the capsule, as reported by Astronauts.

I dont think that smiley fits here. This is a education video. If there is false information. Most people are glad when its corrected with right information.
Thank you for not playing dramatic LOUD music in your videos... We can actually understand your dialogue... Thank you!
Such a great point!
This was excellent. I hadn't up to this point heard much information on the crew capsule. It is quite amazing how relatively comfortable the entire experience has been made by SpaceX. I didn't actually know that the suits could be pressurised, which is very impressive considering how sleek they look. I imagine that in a vacuum they would balloon up and probably make movement difficult? A small price to pay, mind you.
No, the suits are stiff enough to not baloon up (that's why they are custom for each passanger)
Andreas Mogensen has done both types. He was exited to be able to take it of and move around and enjoy the legroom. That's what he said to Danish television anyway.
I love the early insult of want to be competitors. I also love you a speech cadence. Not too fast, so as newbies could understand. Good job team Kevin.
I hated that insult. Not a fan of blue origin, but a fan of safety and success for all. Competition is good.
Bro roasted Blue Origins 😂😂
Your comment, "switch and gauges that they could never fully understand" is an affront to our Apollo Astronauts and the vast knowledge they had of the workings of their spacecraft and its systems. A little respect and knowledge on your part would go a long way to establishing your credibility as a responsible RUclipsr for anything connected to space flight.
Agreed. They knew exactly what all those gauges, dials and switches were. Especially the ones "do not touch" unless advised by ground crew!
Definitely. I had to just check out of the rest of this video with that silly comment.
Was really looking forward to whatever I’d learn but then suddenly not entirely sure what I’d truthfully learn.
I agree. I like the dragon design, and Boeing clearly dropped the ball on Starliner. But by all account the astronauts actually liked the Boeing controls better. Going all the way back to Apollo, astronauts prefer having some level of manual control.
Also it’s disingenuous to show the NASA EVA suit as comparison to the SpaceX IVA suit. Hint: the NASA IVA suit is orange, so should not be hard to find the right picture.
The people going to space in Dragon are not Apollo astronauts.
These astronauts (excluding tourists) are perfectly capable of learning how to understand and operate Apollo era flight controls, but the point is that they don't *have* to. This means that Dragon astronauts do not have to undergo a lengthy portion of training that is focused only on flight controls, and the result is less time and a lower cost to bring astronauts to a level of mission readiness.
Therefore, the Dragon astronaut "could never fully understand" Apollo era flight controls because they don't receive that training.
The presenter did not specifically state that the *Apollo era astronauts* never fully understood the controls. The comment could have been better worded, but you seem to be looking for an excuse to be offended.
Astronauts don't use EVA suits as flight suits. Why do you keep comparing them in your videos? Literally all flight suits are less bulky than EVA suits.
Yeah, like comparing a Tesla to a VW. Probably does that for affect.
Yeah I saw that... Flight's suits are not Bulky at all no matter the Space organisation they come from. Look at Everyday Astronaut russian made suit. A EVA will not be used on a transport mission at all. But rest of the Video was OK. Nothing new though 👍
@@davebooth5608actually it’s “effect” not affect
Because 1. Most people don't know the difference. Let's face it, these videos are not targeted at the space nut demographic. Did you learn _anything_ you didn't already know from this video?
EVA vs IVA
I'm sure someone mentioned it, but CrewDragon does have manual control, about 40 of the and a joystick for bare minimal 'worst case' control by a pilot. It can also be flown via the ipads they carry, or any of the three tilting control panels.
Loved this vid! Thanks! There are loads of great info about this subject all in one place, here.
Amazing content. Thanks for always posting these videos.☺
Insulting to the apollo crews, an instrument panel "they could never fully understand."
I’m always very impressed of the level of detail of your videos. Keep it coming
Level of detail should only impress if details are correct.
Outstanding video. I felt like i just went to space and back on a Dragon - minus the risk of exploding 😅
This was the greatest explaination of information of a flight . Very, Very impressed !!! Keep this kind of info coming.
Favorite line = "hop over the line of technicality", love it!!
Too bad they didn't know to call it the Karman line.
Wonderful summary. I thought I knew the details but I learned a few new ones. Thanks much !
What you just did here is extra-ordinary. Thank you.
Crew Dragon is a great space capsule, much more roomy than Apollo, though you'd never catch me in one, or in Blue Origin, lol. I cannot imagine being trained to go into outer space, or having to don a spacesuit. I have been weightless before but just briefly on an amusement park drop ride that is no longer in service, still it is a wonderful feeling, even if brief.
One must commend those who go to space, it takes indeed the 'Right Stuff' to be in space for an extended period..
True, true. Though Blue Origin seems to think 90-year-old grannies are "the right stuff" for their capsules... Weightlessness gets easier the more you do it.
@@docferringer One must remember 'those 90 yo grannies' were once mothers who brought all of us into this world. Unless you are capable of bearing more pain than they can, I would not mock them son. No matter what 'right stuff' we have, whether we've been in space or done barrel roles in aircraft like I can, there are old pilots, bold pilots, but no old bold 'autopilots' who armchair 'the right stuff'.
Just sayin' The whose "spam in a can" is better than our spam carrier is ridiculous and a dumb argument, especially for Elon Musk fan boys (and girls) given his most recent (and explosive) big bertha launch in Texas.
@@johncillis3431the whole child birth pain is a crap argument. I’ve had kidney stones. I’ve also had confirmation from multiple women who have had both babies and stones that of the two the latter is the more painful. Also, pain has been a nonissue since the advent of the spinal block….just sayin🤷🏾♂️
And what the hell exactly are you talking about with regards to “spam in a can”?? Did you have a stroke…? And the launch in Texas? What about it? Is there a point? Argument? Thought? Anything there?? Perhaps take a nap and just take it easy a while. I’m sure you’ll feel better soon, brother…
@@revmsj It is so easy for a "Man" like you to insult someone by keyboard, thinking I would quiver in fear to the cyberbully of Neanderthalic IQ you obviously are. No excuse for your attitude dude, take your PTSD and mantra to the asylum you escaped from, and for Gods sake if you have fathered children, do not endanger the human genome by fathering more of your "Proud Boys"
Apollo guys knew every switch and gauge.
Fantastic job. Thank you.
Brilliant. Thank you for this exposition.
Great info and visuals! Go SpaceX!!
Over the Top Great !! No gibberish its all very precise to the point and complete. Thank you.
Your video also explains why SpaceX got less money than Boeing. SpaceX already had Cargo Dragon (build using government subsidies) in reliable operation BEFORE they started development of the man-rated Dragon 2. Boeing had not developed ANY manned vehicle since the Space Shuttle.
Boeing didn’t build the Space Shuttle. It was N.A. Rockwell.
Thanks for the excellent video. I really like the detail information and great visuals that help explain the whole process. I'm glad I subscribed to this channel.
@1:34: "...confronted astronauts with a dashboard full of esoteric lights, switches, and meters that they could never fully understand..." brilliant writing! LMFAO!
Yeah, they knew exactly what each and every component was, how it worked, where it was powered from and how to address it if it broke.
A high quality report as always!
I love the video’s quality. Good job, enjoyed it a lot! 😊
I love this video! I can almost feel what it would be like to actually do this! Thank you!
Absolutely wonderful. What a ride!
Superb! 🤸🏽♂️ Thank you. 🤗 Best wishes 🖖🏽
Outstanding
Outstanding! Love the narrative. Seems like a Sci fi futuristic story, but it’s happening for real. Watched this video just after the Tesla Space video about Elon Musk disrupting and saving the American Auto Industry with innovation. I loved the contrast with previous Apollo missions and how Spacex under Musk innovated the hell out of the experience making it far more comfortable, safe, and technologically packed. Wow! Thanks for producing these amazing episodes!
Looks Awesome! Great video as well.
Great explanation, thank you.
Thank you!
that is a brilliant video, thanks for showing us
what a fantastic video, full of great value. Thank you for, amazing job
All those "esoteric dials and switches" the Apollo astronauts ''couldn't fully understand" - oh the horror ...
4:06 Astro Alex on the left 💪🏼🇩🇪
Super! Thank you!
Simply great!
Once again.. DUDE YOU ARE AWESOME 🫵👏👏👏
this is my new favorite channel I just Subscribed! Excellent work!
Very cool. Thx.
Very interesting video not to detailed so the average person can understand what's going on, I really enjoyed watching these videos very informative and intreaging to watch ,look forward to more to come, 👍
WoW!! I wanna have that experience.
And Dragon just looks cool, doesn't it? You said it right before I was going to type it: sleek and modern. It's like the Porche of crewed spacecraft. Then you look at Soyuz and how they are crammed in there so tight, it is like a clown car. They have to use a 2 foot long telescoping metal stick, like an old school teachers pointer stick, to reach some of the buttons and switches in Soyuz. Dragon has these comfy, stylish seats that rotate and touch screens and plenty of cabin space. It is like comparing a Rolls Royce to a Pinto. Dragon looks like a sci-fi video game set in the future in real life. It is so cool. I can't wait to see what Dragon v3 will look like.
I’m sure the astronauts of Gemini knew what each button and gauge was for.
Very much so: during a rendezvous -maneuver gone wrong, Neill Armstrong had to get the capsule back under control while rotating fast, on the verge of losing consciousness
Excellent thank you
Nicely covered. Thanks. ;)
Great vid! 👍🏻🙏🏻❤️
Good presentation!
Great video. Excellent explanation. As I sit and watch Star Trek. Amazing as I was born around the time of Sputnik
Excellent video!!!
Spectrum of Innovations, conformity with the prevailing ideas to support the current thinking of the majority with confidence. Encouraging to new innovation in need of the hour. Inspiring
It would be interesting to see how dragon compares to other crewed orbital and beyond orbit spacecraft.
I love feeling like a fly on the wall to historical events from this video.
Why don't they fire the Draco thrusters prior to reentry, as part of the reentry burn? They are not used in decent and they have a significant mass whose elimination would aid in the reentry process.
It's cheaper to refurbish a slightly thicker heat shield than the draco engines. They wanted to use them for land landings because refurbishing them is much cheaper than all the support ships and helicopters needed for recovery in the ocean as well as the sea water damage. The super dracos have plugs built into their nozzles to keep them protected from seawater if they are not used.
Orbital mechanics are a harsh mistress, you don't want to just go firing engines and altering your carefully calculated trajectory, and then end up burning because you where too steep. Also, the propellant mass hardly matters for reentry.
Finally, even if they fired them, they would still have to take this precautions, because that's what they are. The motors already have valves that close and aren't supposed to leak any fuel, but unburned residues could still be present. So, burn or no burn, they would still have to do this.
That was a great video. 👌
Love it.
Such quality videos
Learned something! 🙂👍
The Red and Green marker lights are cool 😮
The incredible speed of development by SpaceX completely outpaced the previous companies that were building toward space tourism using a ballistic trajectory. True, that kind of tourism is still much cheaper. However, orbital tourism is going to get ridiculously cheaper if they ever can design, build, and certify a man-rated Starship.
As a 64 year old, I had hoped this stuff would have happened in the 80s, but after it didn't (again and again), I had resigned myself to never seeing humans on the moon again or on Mars. I now think it is possible that I may be in the amazing group of individuals that will witness the first steps on the Moon and again on Mars, and may see tourists in orbit or even on the moon.
... And the whole thing is controlled with A SINGLE TOUCH SCREEN. When Consumer Reports was reached for comment, they stated, "We haven't tested it yet but I'm sure wecd rate it as NOT ACCEPTABLE!"
GREAT VIDEO!
I wonder if, with the development of the XL Dragon and the other with the larger cargo fairing, we'll see hot staging of the second stage?
Not Virgin blue orgine technicability , i mean true space ... killed me this one :)))
FOR THIS ALONE YOU WON MY RESPECT AND YOU GOT MY THUMBS UP
And for attacking and insulting the Apollo crews you lost my respect.
@@dougball328 you mean the many apollo guys who got in front of the us congress and talked crap about ELON MUSK ? screw those guys because those are just passengers on a automated ride build by the many engineers .... yap i am pretty fine with no respect from you :)))
That is not what the commentary was in reference to. and I do t give a fuck what you think about me.
So underrated!
Doesn't get the attention the space shuttle did.
Can't wait to see the HLS for Starship.
Maybe the can just mount crew dragon inside Starship??
Having served in the Navy for 41+ years, some of it on submarines, my only regret is that I will never get to take a ride into space.
Когда планируете отправить робота , семена растений и биомассу в сторону млечного пути? Имитировать полет человека. По типу Вояджера 1,2.
Some units were confusing and I had to convert. Anyway thanks for the pictures.
Very cool video.

Recap by Tammy AI
A great video.
That was good👍.
At the same time people die from hunger. Absurdity in its best.
Awesome job NASA 👏 The dragon is wonderfully made. 👏
I wonder what other things there are to pass the time in the capsule aside from checking out the Earth? If you are going to be in there for an extended period of time your bound to get bored like on an airplane. Maybe they can play Kerbal Space Program on those screens?
Andreas Mogensen said he was taking shifts with Jasmine as a pilot. He also said that they are trying to sleep at the same time as on the ISS and preparing for the couple of days of weightless sickness. They eat and talk and prepare for the work up there.
So what happens to Dragon 2 if computers onboard have problems AND they lose contact with the ground? They are kind of screwed. No Buck Rogers manual control like in Mercury or Gemini. Gemini 8 would have been fatal with this system. Its emergency happened outside of the window of contact with the ground, and a thruster was stuck.
Not very much detail in the video. I'm pretty sure they thought about that already. Plus that ignores triple-redundant systems with isolated processes, power supplies and support systems. They also probably have established procedures right on their iPads.
Once Starship is successful at reaching orbit, reentry, mechazilla capture, re-use, and becomes human rated for space, I expect Crew Dragons to transport humans to Starship and then back to earth for quite a while, for its proven track record and extra margin of safety.
The space suits looks like it came from a bad sci-fi movie
They now have in the software the ability to use the super Draco’s in case of parachute failure.
Good job! Very well done!
Hello can you pleas add both feet and meters when u tell how big stuff is because i am from Norway and i have Watcht every single one of the videos on botch channels over 2 years and yee i dont know how mutch 1 feet is but yee love your videos😍
Greetings from the U.S! For reference: one foot is equal to 12 inches, and 1 inch is equal to 2.54 Centimeters. Yes it is confusing. Yes we all use it.
Pause the video and bring up a conversion calculator on a browser page (Google it lol). That’s what I used to do. Now I’ve gotten pretty good at “close enough” estimates on my head from doing it so often.
@@TheHatManColeSpaceX using metric units in their design and construction.
Very interesting! Could you please include the equivalent miles/hour and any other imperial units? Thx
Way cool
I do hope that all will go well but those who volunteer need to be well aware of the dangers and there are many of them,space is the final frontier
1:30 A little more respect for the Apollo capsule would be appropriate.
You also need to remember when the Apollo capsule was designed and built.
Also, to imply that the Apollo Crew didn’t understand the lights and meters is completely ignorant. Every crew member knew every switch, light and meter’s function.
Thank you, Elon!
Congratulations!!🎉❤
What happens to the second stage (and its engine)? Does it eventually re-enter Earth atmosphere and burn down on it way down or stay indefinitely in orbit around the Earth?
What pharmacy do they fill those?
Amazing Video thank you very much for your work
Everyone who is interested shouldtry Kerbal Space Program, the first title.
There you can experience the whole process of beeing the "engineer" of the rockets.
I love falcon 9
But you showd only the descent module of the Soyuz, but you're not counting the Service Module, which privides extra space.
I appreciate the suble Hunter S Thompson quote. LoL
