Every change of more than a minute to this launch's date, as we observed it. Only a move between two dates known to the day counts as a slip; a placeholder such as “NET 2026” rolling to “2027” is shown but not counted. How we classify moves · on-time record by provider
This launch has flown
Liftoff
Counts are flown launches (successes, partial failures and failures) in the SpaceNexus launch record for the calendar year, up to and including this one. The outcome is Launch Library 2’s own label. Booster serials and reuse counts are not in our records; the provider publishes them.
Liftoff Oct 2, 2026, 03:54 UTC. Live chat ran from two hours before liftoff to two hours after.
Every entry is a change we recorded, not a forecast. Our sync checks Launch Library 2 every 15 minutes, so a time is when we saw the change and can trail the real moment. The liftoff time is the one the launch record states.

Falcon Heavy (SpaceX)
Falcon Heavy straps three Falcon 9 first-stage cores together, 27 Merlin engines in all, under a Falcon 9 upper stage. It flies the heavy payloads a single Falcon 9 cannot lift.

The broad sequence of an orbital launch. Details and times differ by rocket and mission; this is a guide, not live tracking.
In the last part of the count the rocket is fuelled, systems switch to internal power and the launch team is polled for a go.
The first-stage engines ignite and the rocket leaves the pad.
The moment of maximum aerodynamic pressure on the rocket during ascent.
The spent first stage separates and the upper stage takes over. Some rockets also drop side boosters earlier in the climb.
The upper stage burns to reach the planned orbit, sometimes in more than one burn with a coast in between.
The payload separates from the upper stage. On a crewed flight the capsule separates and flies on under its own power.
Make your calls before liftoff. Free, no account needed, and each one settles on the recorded outcome of the flight, not on anyone's opinion.
Result: Yes: launches on time
