Kangie, rok temu w Mars rover mission will use pioneering nuclear power source

Don’t worry too much about it: it’s not the 80s and we’re not the Soviets.

Once it’s in orbit it doesn’t matter and if there’s issues during ascent the source will be hardened to prevent catastrophic release.

Realistically though, just send it up on a falcon 9, the track record on those things is _ astounding_.

It’s fine, both of the last two US Rovers are powered off RTGs and several of the deep space probes run off RTGs also. For low Earth orbit and stuff closer to the sun it doesn’t make sense but going further out and especially in a place like Mars where solar panels are prone to being covered in dust an RTG power source makes sense.

Exactly, for its intended use, it’s really the best option we have.

Buzztiger, rok temu w Australia Spent AUD $466,000 on ESA Astronaut Training

Some more information in the Guardian:

theguardian.com/…/australian-taxpayers-paid-46600…

There is currently no mission planned for her as Australia just paid the training cost when she did not get selected into the ESA astronaut chor.

Australia would also now have to pay for a ride to the ISS. The tourist ticket info I found was about 30 MUSD but that’s including the training I think.

she did not get selected into the ESA astronaut chor

Ah, a pity then. I wonder if she could reapply in a subsequent year?

Alternatively, I suppose there’s always a chance she could be hired by a company like Axiom or similar…

Still a bargain compared to Ariane. Europe really needs to get its act together.

Can anyone explain why the water freezes rather than boils away in the vacuum of space?

Great question!

Tar_alcaran, rok temu w Has the RFA ONE Maiden Flight Slipped to Q4 2024?

You can joke about a German company using a beerkeg rocket, but they take their best VERY seriously.

Beerkeg rocket is a little funny, but RFA’s engine tests have been promising. Looking forward to seeing what they can accomplish.

I Wonder how much does it change price per start with this way of hydrogen production.
