Still no signal from the ship. Reentry started a little bit early, so I would think it would be transonic by now.

Edit: Loss of S28 confirmed on the webcast. Now we just wait for Scott Manley and Zack Golden to tell us what happened :) See you all for IFT-4!

Time to go scrub our bathroom floors to get the concept out of the universe's system.

Views of re-entry! Look at that plasma!

Wayward boats again...

https://twitter.com/SpaceX/status/1768243304054092192

New liftoff time is 8:02 a.m. CT, team is clearing a few boats from the keep out area in the Gulf of Mexico

On the bright side, it's now scheduled for after sunrise, and the fog seems to be clearing!

Edit: https://twitter.com/SpaceX/status/1768246454328742222

Shifting T-0 a few more minutes to give boats time to clear the keep out area, now targeting 8:10 a.m. CT

[–] thedarkfly@feddit.nl 4 points 8 months ago

Dang boats, always disappoint. Hopefully it's for the best!

[–] JohnDClay@sh.itjust.works 6 points 8 months ago

Looks like the ship lost roll control. It was re-entering pretty side on instead of belly first. Tim Dodd thought the hot gas thrusters may have gotten clogged with ice.

[–] threelonmusketeers@sh.itjust.works 6 points 8 months ago* (last edited 8 months ago)

Booster survived the boostback burn this time!

Edit: Looks like there was an issue with re-entry and landing burn, but the booster made it further than last time!

[–] reddithalation@sopuli.xyz 6 points 8 months ago* (last edited 8 months ago)

well, that was pretty good. i wonder why the booster reentry was oscilating so much, and the ship reentry didnt seem very controlled either. incredible video from the ship during reentry though.

SECO and nominal orbit insertion for Starship!

[–] Tai@lemm.ee 6 points 8 months ago

Thanks to everyone posting in here, couldn't watch the webcast so it was good to catch up on everything that happened!

[–] clothes@lemmy.world 5 points 8 months ago

That fog cleared fast!

T-0 pushed by 30 minutes: https://twitter.com/SpaceX/status/1768231845551096149

Weather is 70% favorable for today’s third integrated flight test of Starship.

The live webcast will begin ~30 minutes before liftoff, which is currently targeted for 7:30 a.m. CT → https://www.spacex.com/launches/mission/?missionId=starship-flight-3

I think this is the correct link for the SpaceX official feed on X/Twitter: https://twitter.com/i/broadcasts/1LyxBnOvzvOxN

Looks like it's scheduled to start at 6:56 CDT now that launch is targeting 7:30 AM CDT.

Thanks! Added to the main post.

[–] RoundSparrow@sh.itjust.works 5 points 8 months ago

It is looking like it might go on first attempt!

[–] HootinNHollerin@lemmy.world 5 points 8 months ago* (last edited 8 months ago)

Everyday astronaut stream has a thermal camera showing fueling

Onboard views from the booster and ship this time!

[–] RoundSparrow@sh.itjust.works 5 points 8 months ago

45 seconds in, amazing all engines look great

They just announced that the PEZ door is opening.

Hot Staging!

[–] Sibbo@sopuli.xyz 4 points 8 months ago (1 children)

I can't watch any videos right now, how is it going?

[–] Wilshire@lemmy.world 7 points 8 months ago* (last edited 8 months ago)

Starship is descending into the atmosphere

Wings have just folded at 110km altitude

[–] thedarkfly@feddit.nl 4 points 8 months ago (1 children)

So I guess still no orbital flight for test 4? I imagine relighting an engine in space was a requirement.

Yeah, that would seem prudent. Wouldn't want a Starship stuck in orbit and then reentering uncontrollably, a la Long March 5B.

[–] Robomekk@lemmy.ca 4 points 8 months ago* (last edited 8 months ago)

Looks like some sort of fuelling is underway. Or at least chilling lines in the OLM and tower in preparation for filling.

[–] clothes@lemmy.world 3 points 8 months ago

Launch time has been pushed 30 min (7:30 local). The window is 110 minutes.

Hosted webcast is back. Payload door opening and propellant transfer were tested, still awaiting data review. Raptor relight imminent.

Edit: It sounds like Starship decided to skip the raptor relight. Going straight to reentry.

[–] clothes@lemmy.world 4 points 8 months ago

As much as I'd like for those rotations to be intentional, for now I'm assuming they didn't relight because they lost orientational control.

[–] threelonmusketeers@sh.itjust.works 3 points 8 months ago* (last edited 8 months ago)

Prop load soon!

https://twitter.com/SpaceX/status/1768251797846847981

The Starship team is go for prop load but keeping an eye on winds, now targeting 8:25 a.m. CT for liftoff

Starship is supposed to coast for the next 30 minutes, until T+ 40

[–] threelonmusketeers@sh.itjust.works 2 points 8 months ago (1 children)

Any news on the propellant transfer demo?

[–] RoundSparrow@sh.itjust.works 3 points 8 months ago

they announced it completed. Not sure if it worked as intended.

SpaceX are live. Kate Tice and Siva Bharadvaj are hosting.

Prop load has started on ship and booster:

https://twitter.com/SpaceX/status/1768254337204260905

Propellant load of Starship’s upper stage is now underway

https://twitter.com/SpaceX/status/1768255938526626089

Prop load of the Super Heavy booster is underway

Prop load closed out. Winds are looking good.
