After not watching Falcon 9 launches for a while and only paying attention to Starship development, it's weird to look at this livecast and think that Falcon Heavy looks kind of small

[-] threelonmusketeers@sh.itjust.works 7 points 2 months ago

Haha, yeah. Just the Super Heavy booster is about the same height as an entire Falcon full stack. The wide shot of 39-A with both the Falcon and Starship towers in view really puts the scale in perspective.

Starship is about 80% the width of Falcon Heavy - but all the way around and practically all the way up!

[-] threelonmusketeers@sh.itjust.works 5 points 2 months ago

Side booster landings confirmed!

[-] Morphit@feddit.uk 5 points 2 months ago

RIP B1087.

[-] threelonmusketeers@sh.itjust.works 5 points 2 months ago

RIP center core. You did your job well.

SES-2, SECO-2, and norminal transfer orbit.

SES-3 scheduled for T+04:21:18.

Interesting that they are doing a third burn of Stage 2. They mentioned that Falcon Heavy had some additional performance which would extend the lifetime of the satellite. Is this a partial GEO circularization burn?

Liftoff!

Teams completed the launch readiness review, and we are targeting Tuesday, June 25 for Falcon Heavy’s launch of @NASA's GOES-U mission from pad 39A in Florida. Teams are keeping an eye on weather, which is 30% favorable for liftoff
