SpaceX is attempting its 500th Falcon booster recovery during the Starlink 10-57 mission, scheduled to lift off from Launch Complex 39A at NASA’s Kennedy Space Center on Sept. 4 at 8:32 a.m. EDT (1232 UTC); the Falcon 9 first stage B1069 is set to land on the droneship Just Read the Instructions about 8.5 minutes after liftoff.
- Mission: Starlink 10-57 launching from KSC Launch Complex 39A on Sept. 4.
- Booster: Falcon 9 first stage B1069 on its 27th flight.
- Recovery target: droneship Just Read the Instructions (JRTI); ~8.5 minutes after launch.
- Weather: 45th Weather Squadron gives a 70% chance of favorable conditions for the window.
- Milestones: if successful, SpaceX will mark its 500th Falcon booster recovery.
- JRTI statistics: this recovery would be the vessel’s 135th booster landing support.
- Fleet note: ‘‘A Shortfall of Gravitas’’ is returning to Port Canaveral after a recent East Coast assignment.
- Yearly cadence: the flight is SpaceX’s 111th of the year toward a target of at least 170 Falcon launches by year-end.
Verified Facts
Launch is set for 8:32 a.m. EDT (1232 UTC) from LC-39A at Kennedy Space Center. The mission follows a north-easterly trajectory after liftoff and will deploy a batch of Starlink satellites into orbit. The countdown and live coverage begin about an hour before the planned lift-off.
The first stage assigned to this mission, tail number B1069, will be attempting its 27th flight. Records show this booster previously supported cargo and commercial missions including CRS-24 and Eutelsat’s Hotbird 13F, and it has carried multiple Starlink payloads on earlier flights.
SpaceX plans to recover the booster on the droneship Just Read the Instructions (JRTI). If JRTI receives B1069 successfully, it will represent roughly the 135th booster recovery operation involving that vessel. Another East Coast droneship, A Shortfall of Gravitas, has recently been at sea and is en route back to Port Canaveral after supporting a prior Starlink launch.
Context & Impact
A successful recovery would underline SpaceX’s pace of reuse and its operational rhythm in 2025. The company remains focused on maximizing booster reusability to reduce marginal launch costs for the Starlink constellation and commercial customers.
At 111 launches for the year with a public goal of at least 170 Falcon missions before year-end, SpaceX’s cadence affects launch manifest planning across satellite operators, government payloads, and range scheduling at Eastern and Western range facilities.
For Starlink specifically, each batch supports both consumer broadband coverage and network densification in targeted orbital shells. Frequent reuse of boosters like B1069 shortens turnaround time and helps sustain that deployment tempo.
Official Statements
“Deep atmospheric moisture and a stalled boundary across South Florida will produce scattered, onshore-moving showers; timing remains uncertain,” launch weather officers at the 45th Weather Squadron said regarding morning conditions.

Unconfirmed
- The exact effect of small-scale showers on the instantaneous launch window remains uncertain until final weather checks closer to liftoff.
Bottom Line
If the mission proceeds as planned, SpaceX will notch its 500th successful recovery of a Falcon booster, using a veteran first stage B1069 and the droneship Just Read the Instructions. The outcome will reinforce SpaceX’s reuse strategy and maintain the insertion rate for Starlink deployments through 2025.
