Mixel, w €40M to be Invested to Produce Greener Hydrogen for Ariane 6
Mixel avatar

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

Tar_alcaran, 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.

threelonmusketeers,

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

Ashyr, w ESA's Euclid Telescope Has an Ice Problem

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

verity_kindle,

Great question!

Diplomjodler, w It’s official: Europe turns to the Falcon 9 to launch its navigation satellites

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

BakedGoods, w Sweden’s Esrange Gets its First Orbital Launch Customer

Great news! Hopefully the first of many.

threelonmusketeers,

I love seeing all these new spaceports popping up around the world!

Buzztiger, 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.

threelonmusketeers,

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…

evidences, w Mars rover mission will use pioneering nuclear power source

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.

mipadaitu,

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

Kangie, 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_.

@JohnBrownsBussy2@hexbear.net avatar

Outside an atmosphere like Earth’s, everything is already exposed to intense ionizing radiation from the sun/stars. A bit more from an RTG, even a big one, is a drop in the ocean. If we found signs of extraterrestrial life, then we’d want to be extra cautious about not sterilizing by accident, but that’s not currently a major concern. And of course, any sort of nuclear rocket propulsion would need to be handed with utmost care, but it’s also not a major issue once it’s outside the atmosphere.

threelonmusketeers, w ESA Reveals Timeline for Final Push to Maiden Ariane 6 Flight

Nice, can’t wait! It’s been too long since we’ve had a new European launch vehicle…

Buzztiger, w ESA Reveals Timeline for Final Push to Maiden Ariane 6 Flight

It’s been too long since we had an operational European launcher. I hope Vega C and A6 are available and reliable by the end of the year. There is quite a queue of new missions, several of them already had to be launched with SpaceX.

threelonmusketeers, w Ariane 6 inaugural launch targeted for 9 July

Nice! One month to go!

Zachariah, w First detection of negative ions on the Moon
@Zachariah@lemmy.world avatar

The first ESA instrument to land on the Moon has detected the presence of negative ions on the lunar surface produced through interactions with the solar wind.

The European team working with the Negative Ions at the Lunar Surface (NILS) instrument confirmed the success of this scientific mission that flew to the far side of the Moon aboard the Chang’e-6 spacecraft.

The discovery of a new component of plasma at the surface of the Moon opens a new window for space physics and for human and robotic missions in an era of renewed lunar exploration.

verity_kindle, w Europe aims to end space access crisis with Ariane 6's inaugural launch

It seems to be all talk and no rock. Do some manned flights, ESA, and we’ll see.

Tar_alcaran,

Why? Ariane 6 seems more like a Strategic need being filled than a useful launch platform.

verity_kindle,

Strategic need in terms of economics?

threelonmusketeers, w Slovenia Sign Agreement to Become 23rd ESA Member State

Nice!
