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.

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!

[-] threelonmusketeers@sh.itjust.works 7 points 8 months ago* (last edited 8 months ago)

Views of re-entry! Look at that plasma!

[-] 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

SECO and nominal orbit insertion for Starship!

[-] 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.

[-] 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!

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

It is looking like it might go on first attempt!

[-] threelonmusketeers@sh.itjust.works 5 points 8 months ago

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

[-] Robomekk@lemmy.ca 5 points 8 months ago

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.

[-] threelonmusketeers@sh.itjust.works 2 points 8 months ago

Thanks! Added to the main post.

Everyday astronaut stream has a thermal camera showing fueling

[-] threelonmusketeers@sh.itjust.works 5 points 8 months ago

Onboard views from the booster and ship this time!

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

That fog cleared fast!

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

45 seconds in, amazing all engines look great

Hot Staging!

[-] threelonmusketeers@sh.itjust.works 4 points 8 months ago

They just announced that the PEZ door is opening.

[-] Sibbo@sopuli.xyz 4 points 8 months ago

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

[-] 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.

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

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

[-] threelonmusketeers@sh.itjust.works 3 points 8 months ago

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

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

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

[-] threelonmusketeers@sh.itjust.works 2 points 8 months ago

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.

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

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

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

[-] threelonmusketeers@sh.itjust.works 2 points 8 months ago

Prop load closed out. Winds are looking good.
