Payload info: GOES-U
NextSpaceflight:
GOES-U will provide advanced imagery and atmospheric measurements of Earth’s weather, oceans, and environment, as well as real-time mapping of total lightning activity and improved monitoring of solar activity and space weather.

Please post small launch updates, discussions, and questions here! Also feel free to leave feedback or suggestions for the mod team. We’re still a relatively small sub, so feedback from the community is very valuable!"
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
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!
Side booster landings confirmed!
RIP B1087.

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!

T-0 pushed by 10 minutes to 2024-06-25 21:26 UTC.
Weather has improved from
30% favourable to 60% favourable60% favourable to 70% favourable.BECO and side booster separation!
Launch weather is go. Booster fuel load complete, LOX load continues.

Mission Control Audio: "Stage 1, PY, NY, LOX load has started."
Stage 2 RP-1 load has started.
SECO, nominal orbital insertion.
SES-2 scheduled for T+26:19.
Mission Control Audio: "Stage 1 LOX load complete."
Nominal boostback burn of the side boosters, center core MECO, stage 2 separation, M-vac ignition, and fairing separation!
SpaceX and NASA have polled go for propellant load.
Mission Control Audio: "Falcon Heavy tanks are venting for the start of prop load."
Mission Control Audio: "Launch auto sequence has started."
Mission Control Audio: "Stage 2 LOX load complete."
Mission Control Audio: "Max-Q."
NASA webcast is back for the final burn and deployment.
Edit: SES-3.
Edit2: SECO-3 and norminal orbit insertion.
Edit3: GOES-U separation confirmed!
Edit4: NASA webcast concluded.

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
