Answers what I wondered about why the Clipper isn't nuclear powered: “If the Europa mission goes nuclear, it needs four or five [Multi-Mission Radioisotope Thermoelectric Generators],” Curt Niebur, a program scientist at NASA headquarters in Washington, said in a July 23 (2014) interview here during a meeting of the NASA-chartered Outer Planets Assessment Group. “That’s quite a few. If Europa needs that many, that sucks up all the output for the production line between now and 2024. There’s no more left.”
That’s a very good question. Could it be the greenies in our government hate the thought of proven the capability of nuclear power even though several probes have had nuclear batteries?
@@PyroRob69 Exactly. Imagine if we had permanent orbiters powered by Nuclear batteries in orbit around every planet in our system. NASA stuck in solar mode is backwards logic
I like how you sound Canadian. It reminds me of talking to Canadians. I mean, I still live in Kitchener, Ontario, but I haven't talked to a Canadian in weeks. It's funny how India has a space program.
Maybe they just insolated The Clipper's circuits somehow? Glad the launch is on for October! Finding out how thick Europa's Ice Shell is. Mapping It's shape underneath. And how deep it is to the bottom of it's ocean will be amazing.

We will. Spores are READILY spread through asteroid impacts from earth. Ejecta is usually not heated past boiling and experiences no more than 10g. Big clumps shield from radiation. The entire solar system is full of water life! The problem is how much chemical energy there is in those buried oceans. Part of the energy will come from molecules from the surface that the suns UV has given energy to, the other is latent chemical energy of the rocks. A third source though might be fluid flow (for example from gravitational stretching). Bacteria might have structures, which if turned or pushed, provide energy. Life is likely pretty slow down there. Maybe some crazy early animal that's now extinct on earth is now the biggest predator. I'm picturing some crazy looking fearsome 2 cm long feather duster with teeth moving at 1 cm per day lol
I think that Fraser misspoke at the end of the segment on the super massive stars in the SMC. At about 16:03 , he referred to the "Hubble with its infrared view can see the really hot stars". I think that he really meant to say the "*ultraviolet* view can see the really hot stars."

I'm looking forward to seeing Betelgeuse explode on September 6, a big bright star, bursting its way back into theaters. ;) Maybe if you say its name three times it will explode earlier. ;)
Thanks Fraser, any chance of you doing an interview with one of the researchers who now believe Betelgeuse has a companion - or even the whole team - that would be interesting - a lot of commentatros are discussing this, but there is very little specifics (appreciate there may not be many) but a more indepth look at Betelgeuse and the possibility of a companion I am sure would be of interest to many here. The mass and age of the companion has a direct impact on our knowledge of the Betelgeuse itself because it will tell us a lot about the age of the star - and just perhaps - we can pin it's age down a bit better.
I'm somewhat of a new subscriber to this channel, so I don't know if you've answered any questions similar to one big one I have had in my almost 20 years of researching stellar bodies (stars, nebulae, black holes, etc.). Do we know what happens when a black hole dies? Does it ever die or wink out of existence? Does it result in a sort of wormhole effect with the mythical light hole? Does it result in a collection of matter that eventually compresses into a newer galaxy? Does it connect to different universes, even?
It's believed they evaporate over time, slowly increasing in temperature as they lose mass. The final moments are a blast of high energy gamma radiation and then it's gone.
Hi Frasier, you’re one of the few channels on my subs list that over breakfast, I’ll pause when going to the fridge, using a noisy appliance or running a tap. 🚰 Other channels I don’t mind missing a slice or two but not yours. That says something, doesn’t it!
Re the solar “wings” and that solar sail test. I’ve often wondered if a lighter and more scalable design could be an incredibly thin film that you just unroll for 100s of meters, kept rigid by a slow spin. Maybe that could gather the sort of power you need for crewed SEP vehicles, for example.
What I find truly mind boggling… is the lack of standardization in certain types of equipment used in space exploration. There are certain things that should automatically be made to be compatible. Airlocks (and/or coupling systems between crafts and stations, etc), space suits (including any/all umbilical connections, etc), and probably a host of other interfaces that I’m not even aware of. In common industries here on earth, standardization helps to maintain efficiency. In space, it could be the difference between life and death.
Yeah well, I shouldn't expect any useful information from astronomers yet, I mean, the alternative Betelgeuse hasn't been seen so far, so it is speculation. Frankly hope it all goes kaboom! To see a super nova's light during the day will be something to behold.
@@justfellover Binary star orbits are very stable. Once orbits are established, they do not change without external forces (dust, magnetic fields, gravitational waves, etc.). If we can track it, then we can more precisely determine its distance, rotational period, and the eccentricity of the orbit.
@@GregConquest The stable binary orbits you speak of have a greater separation. This one, if it exists, is close enough for tidal forces to be large. see 1:20
@@justfellover @0:55 he says the second star is 2.5 times the radius of Betelgeuse away, and the animation there is more accurate too. Someone screwed up with the illustration at 1:20. That star is one radius away from the center of Betelgeuse. It is misleading.
While I'm sure Butch & Suni were happy for some more space time, they are both about 60 years old. Their bodies might not respond to unexpected extended stays in space like when they were 30. Also, as pilots, they can't be excited about taking an automated taxi home, and missing the excitement of piloting a risky craft home. That's what test pilots love. Maybe in their old age, they will enjoy a more safe trip home. We will never know until they write their books, as all public statements will be NASA aligned sentiments.
@@PowerScissor they have been in space longer than you have had sex so they are fine they are happy and they're going on a superior spacecraft in February so don't worry about them even Neil deGrasse Tyson said that they are fine and they are experts and all that man
curious why they dont use the moon as a gravity assist for missions to mars venus and other planets would it make much difference & do they already do this but it just doesnt get mentioned much?
I didn’t even think about spin launch on the moon!! That’s genius! Cause it’s not as practical on earth with our gravity but the moon would be PERFECT!!! I like spin launch, I think they have potential!
Thinking about the large solar panels... If we sent a satelight to Jupiter in an orbit perpendicular to the equator plane, all it did was collect sunlight, transmit data to Earth, and transmit energy to other satelights. We could then send cheaper satelights to piggyback off this master satelight. However, transportation is the most expensive part of the project, so it may not be a good idea.
Question/discussion for the Q&A; Does it not seem like great hubris that nobody is asking for a true, long-exposure deep field from JWST? I want to see *dim* early galaxies, not only the brightest ones-does anybody else?
A question for the question show! As ridiculous and as insanely expensive as it may be, what would it take to bring back Voyager 1? Would it be technically possible using chemical rockets?
October 10th??! I haven't been paying close attention and I thought Europa Clipper was still some hazy, "maybe somewhere in the next few years if it's convenient" kind of mission. I didn't realize it was this far along!🎉
Spin launch enough lunar dust into L1 and you have 1. A tunable sunshade to manage global temperature change. 2. Stop tossing up dust and the sunshade gets cleaned out by solar wind. 3. A profitable business model for early lunar development.
Did they do a test launch of SLS before its first mission? I don't remember if they did (though it does have proven engines). Amazorigin isn't SpaceX. They have a more traditional "get it right the first time" approach to designing rockets. If they're launching a payload it means they think they're ready. We'll see. If they succeed, they will be ahead of Starship.
@@Pushing_Pixels I don't follow SLS much, but I know they flew an uncrewed mission around the moon with little more than cameras. New Glenn had two recent incidents while still in development, and yet NASA is putting payload on a rocket that to my knowledge hasn't even had a static fire test. The system as a whole has never been tested, and for all we know it could blow up on the pad or fail to reach orbit. Look at all of the problems Starliner has had. Boeing said it was ready and safe to fly, but it wasn't. I just find this strange.
@@javaman4584Prepare to be amazed! SpaceX has led us to believe you have to blow up 40 rockets before getting close to orbiting one. Starship is an entirely new innovative design throughout. More conventional rockets need much less iterative design and building techniques. Just look at Ariane 6 recently, first ever launch and success. I admire that, very competent engineering and quality control. I suspect New Glenn will achieve much the same success. New Glenn is more powerful than Ariane 6 and Falcon 9, indeed it competes with Falcon Heavy. So it will be impressive to see it succeed first time. In fact it has a huge payload bay compared to Falcon Heavy, 23 feet in diameter. NASA is only paying 20 million dollars for this launch so it's basically getting a free ride due to the risk of failure of a first flight. Fingers crossed 🤞
If i'm not mistaken, this is the first time astronauts have flown to space in a capsule and returned in a completely different type of capsule, which is kinda cool to me.
How would the planets around a star be affected by its companion going supergiant like betelguese? I imagine the center of gravity would stay the same so orbit wouldn't change, but would being closer to the surface lf betelguese make them hotter? Would it affect habitable zones?
The numbers quoted for the quantity of water that can be extracted from lunar regolith seem inconstent: if one cubic meter of regolith contains one liter worth of water, then one would need to process at least 50 cubic meters to extract 50 liters of water. That would represent about 80 metric tons of regolith (at a 1.6 g/cm3 density), much more than a metric ton as it is said ! Which number is correct then?
1 liter of water is in 1 metric cube of regolith but chinese plan isn't getting this water. This new system creates new water from oxygen and hydrogen trapped in the regolith. There is 1 liter of water but also 50 liters worth of oxygen and hydrogen
@@bruhus_momentum Thanks a lot for the clarification! Indeed that's what the subtitles at 12:50 explain, I hadn't read them. What Fraiser says is quite different: heating at 900 C instead of 1500 C and that only *water* trapped in the regolith is collected...
If it's true that Alpha Orionis has a small G-class companion star then I do believe is what astronomers refer to as a spectrographic binary where the two stars can only be told apart by their respective spectrums.
Probably lower power cost and simpler construction. Railguns require a lot of components (e.g. each electromagnet on the rail would need its own capacitor bank), whereas spin could just use one big electric motor.
Astronauts: yes I am sure they don't have health concerns (the male in particular as the space affects men more than women) and I am sure they did not have personal activities, maybe including a wedding programmed. So yes they are affected big time. It's a bittersweet situation not just a sunny experience.
Is there a reason we can't launch rockets backwards towards Mars? Wouldn't that be shorter than waiting two years if you missed the initial launch window?
4 years ago I left a comment hypothesizing that a body very near Betelgeuse moved inline with earth blocking the light causing the disruptive behavior. 😂🎉
6:54 - The radiation is an issue for spacecraft hardened and designed to withstand it for a few weeks or months. It could be a *show stopper* for the development of life in any cozy ocean.
Since both of the Starliner astronauts have already spent extensive time in orbit on previous missions, will this new extended mission mean they will set new records total time spent in space?
How is there enough food on the ISS for this extended mission? As far as I know there has been no resupply mission. NASA isn’t telling us the whole story here.
@@rolandthethompsongunner64 NASA has some extreme prepper personality traits. There is enough food for more than a year assuming the maximum size crew. The Space Shuttle had issues. NASA is prepared in case another type of spaceship is grounded for an extended period.
You said before that space mining would never be used to bring material back to Earth. And now they plan to bring back Helium-3. I've never seen the community tab.
Enough helium-3 to provide all of humanity with fusion fuel for the next 1000 years, while earth itself doesn’t have enough of it… seems like it could be worth it perhaps. Of course, fusion technology still “has a few kinks” to be worked out, lol.
It seems like gas from the moon might be a slightly different situation than say, gold from an asteroid. Still, dont know if we could afford to start bases on the moon specifically for that
Couldn't they just make adapters so the connectors on their own suits can hookup to the Crew Dragon spacecraft suit connectors? This would be something that us mechanics on earth might do.
Wonder how far Earth is 1:47, if that would be our Sun. Knowing Betelgeuse's radius is the size of Jupiter's orbit...the sun must look like a pinpoint sized light. Earth might be a quarter the distance from the orbit
These incompatible space suits bring up a problem with privatised space exploration. It would be tricky getting the USA, China, Russia, India etc. all having compatible connections (door and suit connectors for example), but within one nation, it would seem the sensible option. But these USA teams are businesses - they aren't doing science, they are investing in tech from which they hope they will get a profit (if only from the taxpayer!). So they can't share info with their 'competitors'. It is going to be a drag on the whole thing, far out into the future. And there will be unnecessary tragedies as a direct result - which in turn will set things back.
14:12 perhaps a spin launcher on the moon could double as a possibility to create artificial gravity for the people living on the moon, when they do not throw helium-3 down to earth they can attach a capsule where they can sleep and relax while it rotate at a suitable speed

The problem is how much chemical energy there is in those buried oceans. Part of the energy will come from molecules from the surface that the suns UV has given energy to, the other is latent chemical energy of the rocks.

@@frasercain So when Alpha Centauri A goes Red Giant first. B will orbit it much like the Betelgeuse System's new companion? Except at 10 AU.
I'm sure their bank accounts would be enjoying the, ahhhh, staying away allowance, too
Can't we do a new horizon type observation of Betelgeuse?
"...never use Imperial"??
Well that's not true.
But I wish it was.
If/when Betelgeuse goes pop, what effect will this have on the companion star?
Does anyone know if we have an operational telescope that could make a direct observation of Betelgeuse potential companion?
What's the advantage of a spin launcher over a railgun? No vacuum tube required.
Probably lower power cost and simpler construction. Railguns require a lot of components (e.g. each electromagnet on the rail would need its own capacitor bank), whereas spin could just use one big electric motor.
Astronauts: yes I am sure they don't have health concerns (the male in particular as the space affects men more than women) and I am sure they did not have personal activities, maybe including a wedding programmed. So yes they are affected big time. It's a bittersweet situation not just a sunny experience.
Is there a reason we can't launch rockets backwards towards Mars? Wouldn't that be shorter than waiting two years if you missed the initial launch window?
I can't believe you would pass up on an invitation to attend a maiden flight of a new launch vehicle
I get an invitation to all of them. I can't afford to attend them.
Would LOVE a video on dark Forrest having recently listened to the three body problem and its sequels 🫶🏽
A Canadian lecturing on units of measure.. freedom units are more consistent!
4 years ago I left a comment hypothesizing that a body very near Betelgeuse moved inline with earth blocking the light causing the disruptive behavior. 😂🎉
2002ve? Circulating Venus ?could we alter it's path to become a moon of Venus and then use it as a base for studying the planet?
6:54 - The radiation is an issue for spacecraft hardened and designed to withstand it for a few weeks or months. It could be a *show stopper* for the development of life in any cozy ocean.
Would a few kilometers of ice give enough protection?
One meter is enough.
Since both of the Starliner astronauts have already spent extensive time in orbit on previous missions, will this new extended mission mean they will set new records total time spent in space?
Our 2 delayers on the ISS: not only extended vacation but now additional merch !!
How is there enough food on the ISS for this extended mission? As far as I know there has been no resupply mission. NASA isn’t telling us the whole story here.
@@rolandthethompsongunner64 NASA has some extreme prepper personality traits. There is enough food for more than a year assuming the maximum size crew.
The Space Shuttle had issues. NASA is prepared in case another type of spaceship is grounded for an extended period.
UBER need to sponser the pick up.
You said before that space mining would never be used to bring material back to Earth. And now they plan to bring back Helium-3. I've never seen the community tab.
I can't see how it will ever be economical. Leaving whatever is mined or collected in space and using it in industry up there would be most efficient.
Enough helium-3 to provide all of humanity with fusion fuel for the next 1000 years, while earth itself doesn’t have enough of it… seems like it could be worth it perhaps.
Of course, fusion technology still “has a few kinks” to be worked out, lol.
It seems like gas from the moon might be a slightly different situation than say, gold from an asteroid. Still, dont know if we could afford to start bases on the moon specifically for that
Betelgeuse is usually pronounced bay-tell-goose. But we all call it Beetle Juice. It's a fun name.
Loser
Great movie too!
"Mirab, with sails unfurled."
"Chandra, when the funding fell." 😢
@@chrischaplin3126 lol too true
This one is a one horse race.
Blue Origin is going to go from never getting to orbit to a serious Space player in October?????
I wish them well, but am not holding my breath.
Couldn't they 3d print metal adapters for the space suit problem. Not an engineer.
Couldn't they just make adapters so the connectors on their own suits can hookup to the Crew Dragon spacecraft suit connectors? This would be something that us mechanics on earth might do.
Wonder how far Earth is 1:47, if that would be our Sun. Knowing Betelgeuse's radius is the size of Jupiter's orbit...the sun must look like a pinpoint sized light. Earth might be a quarter the distance from the orbit
Does this mean our theory that Betelgeuse going supernova has changed?
These incompatible space suits bring up a problem with privatised space exploration. It would be tricky getting the USA, China, Russia, India etc. all having compatible connections (door and suit connectors for example), but within one nation, it would seem the sensible option.
But these USA teams are businesses - they aren't doing science, they are investing in tech from which they hope they will get a profit (if only from the taxpayer!). So they can't share info with their 'competitors'.
It is going to be a drag on the whole thing, far out into the future. And there will be unnecessary tragedies as a direct result - which in turn will set things back.
Hope they don't forget the crowbar so they can pry the dam thing loose!
Why hasn't JWST observed Battle Juice yet?
#CaptureTheCosmos
I find the idea that suit interfaces for NASA, from whichever vendor, are not standardized. Who's running this circus? Why aren't they fired?
It is like, when you went to space, and wound up in prison
The Moon is a Harsh Mistress
14:12 perhaps a spin launcher on the moon could double as a possibility to create artificial gravity for the people living on the moon, when they do not throw helium-3 down to earth they can attach a capsule where they can sleep and relax while it rotate at a suitable speed

@1:20 Betelguse’s mass is 10~20x that of our Sun…
He was speaking of the estimated mass of the theorized companion star.
Is Starliner a failure if it returns intact? I think this is, so far, just an exercise of proper caution.
Uhm.. did I hear you say you can’t afford to go to an event you were invited to?
C’mon comunnity… Let’s send him there!
