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?

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.

SECO, nominal orbital insertion.

SES-2 scheduled for T+26:19.

Side booster landings confirmed!

Nominal boostback burn of the side boosters, center core MECO, stage 2 separation, M-vac ignition, and fairing separation!

BECO and side booster separation!

Mission Control Audio: “Max-Q.”

Liftoff!

Mission Control Audio: “Stage 2 LOX load complete.”

Mission Control Audio: “Stage 1 LOX load complete.”

Launch weather is go. Booster fuel load complete, LOX load continues.

Stage 2 RP-1 load has started.

Mission Control Audio: “Stage 1, PY, NY, LOX load has started.”

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.”

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

The music sucks

You take that back. John Williams is an international treasure, and the only aspect which was consistently good throughout all nine films. Rey’s theme, March of the Resistance, and Jedi Steps and Finale were all stellar in my opinion.

Same. Core memory unlocked.
