Morphit, w Sentinel-1C Launch Thread (return to flight of Vega-C)

Seperation confirmed! Congratulations ESA and Arianespace.

AVUM+ ignition 2

AVUM+ in coast phase.

The Arianespace webcast experienced an anomaly between T+5:52 and 408s, the Vega C rocket seems to be unaffected.

It appears that we have Staging 3-4, Zefiro 9 burnout and separation, AVUM+ fourth stage ignition.

Décollage!

Trajectory and propulsion are “nominale”!

Great launch - there’s an article from ESA with a video describing the commissioning and operations to come: Eclipse-making double satellite Proba-3 enters orbit

Morphit, (edited ) w Watch eclipse-making Proba-3 launch today
@Morphit@feddit.uk avatar

Due to an anomaly detected in PROBA-3 spacecraft PSLV-C59/PROBA-3 launch rescheduled to tomorrow at 16:12 hours.

That’ll be 2024-12-05 10:42 UTC. Via the ISRO Youtube stream: www.youtube.com/watch?v=PJXXLLw0PBI

Edit: I suck at time zones - IST is UTC+0530

What an unfortunate photograph of those two people. Of all the ones they might have picked 😳

threelonmusketeers, w Super heavy-lift, frequent flights to space for Europe: Protein study results

Notables:

The potential proposed use cases of “a solar electricity generator and a data centre” seem not super practical.

The acronym is atrocious: “euroPean Reusable and cOsT Effective heavy lIft transport investigation” (PROTEIN)

The rockets look cool though. I’m excited to see what Rocket Factory Augsburg can do.

Morphit, w Ariane 6 joint update report, 16 September 2024
@Morphit@feddit.uk avatar

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.

Buzztiger,

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?

threelonmusketeers, w Euclid Galaxy Zoo – help us classify the shapes of galaxies

First came across this project on DeepSkyVideos several years back. Glad to hear that it’s still going!

Buzztiger, w How to watch the Ariane 6 Launch tonight (Tue) at 21:00 CEST (Amsterdam/Berlin)

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.

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.

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.

threelonmusketeers, w CO3D & MicroCarb Launch Thread

AVUM+ ignition 5 and shutdown 5 confirmed. Sounds like a nominal passivation burn.
