Special Preparations for 'Dual Catch' - Super Heavy booster and the Starship
- The "Squeeze Test": The Super Heavy booster (Booster 22) was rolled out to the Starbase launch pad for a structural "squeeze test". The mechanical arms lifted and held the booster at the exact height of a real catch to verify that the arms close with the correct force and that the vehicle's catch points can endure the structural load without damage.
- Ship Catch Fittings: For the upper stage catch, Starship is equipped with two specific load-bearing fittings located just below its forward flaps, which the tower arms will grab once the vehicle slows to a hover.
- Contingency Planning: If go/no-go safety conditions are not met for a tower catch at the moment either vehicle arrives, SpaceX has designated contingency splashdown zones in the Gulf of Mexico for the booster and the Pacific Ocean for the Ship.
- Super Heavy (The Booster): Following its initial ascent, the booster will execute a series of engine burns to slow its descent and return to Starbase for a tower catch approximately 6.5 minutes after liftoff. SpaceX has successfully caught the booster on three prior missions (Flights 5, 7, and 8).
- Starship (The Upper Stage): Because it travels to orbit, the upper stage catch presents a significantly more demanding challenge. The Ship will reach orbital velocity, circle the Earth about 14 times at a 275 km altitude, and deploy 26 next-generation Starlink V3 satellites.
- The Ship's Return Sequence: After spending over 22 hours in space, the Ship must survive the intense heat of atmospheric reentry, maneuver back to the launch site, perform a flip, and use its Raptor engines to slow its descent before the chopsticks can secure it.
While Starbase has two launch towers, Flight 15 will execute both catches sequentially on a single tower at Orbital Launch Pad 2 (OLP-2).
Super Heavy Catch (~T+00:06:35): Booster 22 (the first Block 3 / V3 booster to attempt a return) lifts off from OLP-2 and returns to the same tower's Mechazilla arms roughly six and a half minutes after launch—marking the first catch attempt at Pad 2.
Clearing the Tower: Because Ship 42 remains in orbit for nearly a full day, ground teams have more than 22 hours to lower Booster 22 onto a transport stand, roll it away, and reset the OLP-2 chopstick arms.
Starship Catch (~T+22:32:34): After completing roughly 14 orbits and deploying 26 Starlink V3 satellites, Ship 42 reenters and returns to the exact same OLP-2 tower and chopstick arms for the second catch.
