Week in Space Data, every Friday.
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

Liftoff

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.
What you’re watchingLabPadre: LabPadre’s remote cameras at SpaceX’s Starbase in Texas and on Florida’s Space Coast; the title above says which one is on air. They run around the clock, and most of the time nothing is moving.
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.

A Moon mission. See where it fits in the US vs China race to the Moon, the Moon landing timeline and the list of every Moon mission since 1958.
Part of a tracked program. See it on the NASA Commercial Lunar Payload Services (CLPS) tracker, with the program's contracts, satellites and launch slips.
