I wonder how close they can get the regolith stimulant to match actual lunar regolith.

I wonder why they just couldn’t re-use the Hollywood set from the moon landing in '69. /s

They left it up on the moon, sadly.

They’ll hire Michael Bay this time and make it all CGI

Morphit, miesiąc temu w Ariane 6 joint update report, 16 September 2024

Doesn’t seem like much info on the APU anomaly:

Analysis shows that one temperature measurement exceeded a pre-defined limit and that the flight software correctly triggered a shut down

Sounds like the fix is changing the start up procedure such that it doesn’t reach the temperature limit. It would be nice to know why it went outside what they deemed safe but I guess it is rocket science.

Yes, not really the complete picture of what happened.

Would have there been actual damage to the system or even destruction if the software did not shut down? Or was the temperature threshold set too conservative? Did the thermal simulations not match the observed temperatures and if so why?

What’s the solution to this problem now for the next flight?

proper, miesiąc temu w Juice confirms that Earth is habitable

“We are obviously not surprised by these results… it would have been extremely concerning to find out that Earth was not habitable! But they indicate that MAJIS and SWI will work very successfully at Jupiter, where they will help us investigate whether the icy moons could be potential habitats for past or present life.”
