Great space flight channel, but... An RTG is not a mini nuclear reactor. It doesn't actually control a nuclear reaction. Electricity is generated from the heat of radioactive decay.
Yeah, I'm surprised that that error snuck into the script, given the team's combined knowledge. This was one of the few times in which an NSF video has made me say, out loud, “uh... no.” RTGs aren't even a complicated concept, and have no moving parts, AFAIK. It's essentially "use 200-year-old thermometer tech to get electricity from hot, spicy rocks" - and a rare case of humanity generating electricity using a process that _isn't_ just boiling water with increasingly-elaborate machines! 😆
I have seen "nuclear reactor" used in context of anything that involves a nuclear changes like "Natural Nuclear Reactor" in africa. So if you're using naturally occurring fission and harnessing power that would still in some sense be a nuclear reactor. even though there is not much controlling the reaction. But yeah strictly speaking it's not a thing that controls a chain nuclear reaction, so you're right.
@@gagiotter4114 From my understanding, "natural nuclear reactors" still involve controlled fission chain reactions, while RTGs don't use fission at all, instead utilising nothing but decay heat.

What confuses me is that they littered the samples over the surface, rather than keeping them on the rover. That complicates returning them a lot. There must be a really good reason. Are they that heavy?
They always take two samples, one to keep on the rover and one to drop on the ground. Plan A is to have the rovers stash be loaded on the return vehicle, but if something happens to the rover a different craft will come and pick up the dropped tubes.
Its probably easier just picking up samples from the ground instead of inside the rover. Also if the rover dies before the sample return mission the samples inside would be stuck
Hope to see Rocket Lab to step up successfully & make this Mars mission a reality soon 🙏. More companies involved in Space exploration the better. BOK BOK Blessings 🙏🌺🌼🌸
Why are the Mars samples being left all over the Martian surface? Wouldn’t it be easier to return them if the samples were currently stored together in the existing rover?
They are too, but if something happens to the rover and it can’t return the samples they drop a duplicate sample on the ground for another rover to grab.
Next week is packed... I hope we get New Glenn photo bombing the Starship flight kr vice versa. also some more opportunities for Don Petit to capture more from orbit.
They should not give any Mars contracts to spacex until they deliver on Artemis and HLS. There are just so many questionmarks right now regarding everything from orbital refueling to building the actual lander.
This week in space flight………could we get a maybe monthly check of all missions including interplanetary? This week voyager 2 is 218 million miles away and made an adjustment. Idk
I think it would make sense to turn the Super Booster of Starship into a multi-purpose vehicle, that can be used to launch anything into space. By means of an adapter, it could be turned into a 3 stage rocket, eliminating the need for all those SLS things etc. Just put a second stage on top of the booster and on top of that your LEM and Command Module or whatever. And there you go! This can even be done in a matter of months if people set their minds to it like in the sixties, imo.
Nazwanie RTG reaktorem jądrowym może prowadzić do nieporozumień, sugerując, że działa on na zasadzie reakcji łańcuchowej i wymaga systemów chłodzenia czy kontroli neutronów, co nie ma miejsca. RTG jest bardziej zbliżony do "baterii atomowej" niż do reaktora.
I mean… star ship will be bringing back stuff by then anyways right? Starship can at least bring a drone to collect something and also a smaller return system. Doesn’t really seem like the mars mission is even a good idea at all. There’s just gona be better tech by time it comes out
RUclips unsubscribed me and will not let me re-subscribe without joining the channel as a paying member. I will continue to watch your videos if I see them, but RUclips is no longer presenting them automatically like they did when I was subscribed.
Well, there are technically two copies of each sample--one set on board the Preseverance rover, and another set scattered across the Martian surface. It would be great to see one mission collect the samples on board the rover, and a different mission collect the samples scattered on the surface. 😊
I feel that unfortunatley science is pretty much doomed in the coming years. Money will most definitely be re-directed to natural resource extraction etc.
Collaboration is highly overrated. It's competition that got NASA to the Moon. Its focus on collaborative projects like the ISS and the lack of competition in the post-Soviet era that led to NASAs decline. Only now that China is looking like they have the momentum in the Space Race, will there be any kind of fire lit under NASAs ass.
SpaceX intends to land five Starships on Mars in 2027 with equipment to manufacture propellants. Certainly the five Starships intended to land on Mars in 2029 are intended to return to Earth because they are carrying Muskonauts. These missions could deliver hundreds of tons of equipment including dozens of rovers, and could return at least a hundred tons of samples to Earth by 2031.
@@_mikolaj_ Unfortunately I agree re Muskanauts but there is at least a chance that SpaceX might land (as opposed to crash) cargo on Mars by maybe the 2030 launch window so a landing in 2031. If SpaceX is already planning to develop the technology to do that at its own expense then maybe it could sell a cargo mission to NASA for basically the cost price of the vessel plus the tanker refuelling flights in order to make NASA, perhaps not an offer it can’t refuse, but certainly an offer that could cost way less than a NASA in-house solution or what anyone else could bid. SpaceX might even be able to reduce the bid even below cost because if the cargo-to-Mars estimates for a single Starship end up being anywhere close to reality then I doubt that the sample collection payload would take up the whole cargo capacity so SpaceX might be able to pitch its bid as a ride share. The big elephant in the room there though is whether the landing site for the sample return would be anywhere close to a landing site that SpaceX was interested in for any of its own cargo. The other big elephant in the room is whether NASA would consider the SpaceX cargo landing process safe/proven enough by 2030 for it to be willing to risk its payload on that transport system. I still think that SpaceX getting anything to Mars by 2031 is definitely very much open to debate right now but I do think that things will be clearer by this time next year. If SpaceX can get anything like the number of test flights that it is applying for done in 2025 and maintain the same sort of progress between flights that we’ve seen between IFT-1 and IFT-6 then 2025 might just be a pivotal inflection point in the Starship development program but conversely if SpaceX fails to make very significant progress in 2025 then all sorts of timelines start to look foolishly optimistic.
U've covered mostly of both old and new current Space events. Highly appreciated. My highest interest is the full determination of SpaceX-Flight 7 launch on the 01-13-2025 🙏 all my wishes and prayers. BO by Bezo's N.Glenn it's his "que sera, sera" legacy. Tht's my comment. Thank U ✨️

SpaceX can do it with Starship when they do the first unmanned return flight.from Mars. Land in that area, get that robotic doggy dog from Boston Dynamics or Tesla humanoid pick up those darn cans and fly back. They’re gonna fly there anyway testing Starship likely much earlier than early 2030s. Happy New Year!.
Im thinking ……Elon Musk could successfully land astronauts on Mars, allowing them to collect and conduct preliminary in-situ studies of rock samples. These astronauts could then return to Earth and personally deliver the samples to Bill Nelson and NASA before 2035, whether or not the $7.7 billion funding is secured.

Are those J Webb earings? How cool. Someone make me a Falcon 9 themed pen already.

Lol, the sls is still a thing
Bechtel, as the company that almost botched the TMI clean up?
this would litterally fund a human mission where the humans could simply pick up the samples and go back ..
