FYI to everyone: there are several fake "ESA Official" YouTube channels running deepfaked Elon crypto scam streams that claim to be "Ariane 6 Launch Stream".

They're nothing new, but sharing in case anyone hasn't seen it before. Those aren't real streams!

Upper stage separation

[–] threelonmusketeers@sh.itjust.works 7 points 4 months ago (1 children)

That was one of the more cinematic stage separations I've seen in a while. Beautiful shot from the upper stage camera.

[–] Buzztiger@feddit.nl 4 points 4 months ago

Yes beautiful!

[–] clothes@lemmy.world 5 points 4 months ago (1 children)

I'm impressed by the quality of their onboard cameras, without the help of starlink.

Seems like they might be between ground stations right now. Haven't seen live video from the upper stage for a few minutes. Telemetry still looks good though.

The tech-demo phase of Ariane 6 is still in progress but has shown an unexpected result which will only affect the end of the mission.

On the webcast, they stated that the Auxiliary Propulsion Unit (APU) switched off shortly after it it powered up after SECO-2. Without the APU, they have no way to settle the propellants in the tanks, and thus can't reignite the upper stage for the final burn.

From the live camera feed, it looks as though the upper stage was spinning, so there may have been some loss of control as well.

ESA webcast is live! https://youtube.com/watch?v=B0oFpOJaIYc

You're welcome! Glad people find these threads useful!

So launch window start has been shifted by one hour according to my info: 21:00 - 00:00 Amsterdam/Berlin CEST.

[–] threelonmusketeers@sh.itjust.works 3 points 4 months ago

Thanks! Updated the main post.

[–] threelonmusketeers@sh.itjust.works 5 points 4 months ago* (last edited 4 months ago)

Looks like we have SECO-1 and nominal orbit insertion!

Edit: Webcast commentary scheduled to resume T+52 minutes for a circularization burn and the first set of payload deployments.

[–] threelonmusketeers@sh.itjust.works 4 points 4 months ago

Fairing jettison confirmed!

[–] ricdeh@lemmy.world 4 points 4 months ago* (last edited 4 months ago)

All nominal, successful booster separation, fairing jettisoned

[–] threelonmusketeers@sh.itjust.works 4 points 4 months ago

MECO, stage separation, and stage 2 ignition confirmed!

[–] Buzztiger@feddit.nl 4 points 4 months ago

Wohoo a proper launch thread. Thank you!

Let's hope they manage to launch at the beginning of the window.

So for Amsterdam/Berlin timezone that's starting at 20:00 tonight.
