SpaceX has moved the vehicle pair designated for Starship Flight 15 to the Massey’s Outpost test site for cryogenic proof testing. Super Heavy Booster 22 was rolled out of Mega Bay 1, followed by Starship Ship 42, which is undergoing its second round of testing at the facility.
What Happened
Booster 22 and Ship 42 are currently at Massey’s to verify structural integrity under thermal and pressure loads. For the ship, teams are loading liquid oxygen into the LOX tanks and liquid nitrogen into the methane tanks, monitoring temperatures, pressures, and strain gauges over several hours. Booster 22’s cryogenic series precedes Raptor engine installation in Mega Bay 1 and a static fire at Pad 2. Ship 42, which previously completed two cryo campaigns, requires engine installation in Mega Bay 2 and its own static fire to proceed.
The testing occurs while SpaceX awaits a confirmed launch date for Flight 14, which is targeting mid-September. Flight 14, pairing Booster 21 and Ship 41, is planned as the first dedicated orbital attempt from Starbase, including the deployment of operational Starlink V3 satellites. Both Flight 14 vehicles are currently awaiting rollout from the Production Site to Pad 2.
Why It Matters
The progress of the Flight 15 hardware is contingent on the success of Flight 14. If Flight 14 meets its objectives, SpaceX could attempt a catch of the booster, the ship, or both on Flight 15. A booster catch would mark the first recovery of a Block 3 Super Heavy at Starbase, while a ship catch would represent the first tower recovery of an orbital upper stage. Catching both vehicles would require a wider landing-zone case approved by the FAA, a regulatory hurdle that previously led to the removal of the ship catch from Flight 14’s immediate plan.
SpaceX has filed a communications permit for Flight 15 listing an orbital second stage, with a requested operational period from September 28, 2026, to March 28, 2027. However, the launch date remains dependent on Flight 14 results, static fire outcomes, pad turnaround times, and regulatory approvals. Pad 2 is currently the only orbital pad in service, undergoing refurbishment to support these launch and catch operations.
The Bottom Line
Flight 15 testing is underway in parallel with preparations for Flight 14, but the timeline for the next mission remains fluid. A best-case turnaround for Flight 15 is approximately one month after Flight 14, provided there are no anomalies or regulatory delays.
