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?
If it reenables European sovereign and independent access to space it’s a success. Fingers crossed that it’s also as reliably as A5. Commercially I agree.
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.
we don’t want it to reactivate in the future and begin transmitting again if its solar panels find sunlight.
Why go to so much work to ensure it can never be turned on again? What harm does it do to move the satellite to a graveyard orbit and just leave it listening?
Argonaut will be a multi-role lunar lander capable of delivering up to 1,800 kilograms of cargo to the surface of the Moon.
According to a Phase A/B1 development document published in July 2024, ESA is targeting 2031 for the launch of the first Argonaut mission. The lander is set to launch aboard an ArianeGroup Ariane 64 rocket from the Guiana Space Centre.
I love that we launched a spacecraft with the sole purpose of measuring the positions of as many stars as possible, just because we could. Well done Gaia, and all the teams who worked on it.
A quick search says final, because it is supposed to enter Mercury’s orbit late this year and then split into two different spacecrafts: Europe’s Mercury Planetary Orbiter and Japan’s Mercury Magnetospheric Orbiter
They eat cod in space? I mean, the Portuguese eat a lot of cod. They have a bajillion recipes, generally amazing. Don’t get me wrong, I love eating in Portugal, but I imagine that cod must have been a part of the navy selection process. Could be that they have developed a space-ready Belem cakes. If so the astronauts are fucked. They’ll return fat as fuck! Those things are addictive.
