SpaceX's Upgraded Starship S40 Heatshield to Make History...Totally Ahead of Time!

This update covers SpaceX’s rapid progress toward the first midair Starship catch, with Ship 40—the second Block 3 prototype—fully stacked in just 114 days and passing two clean cryogenic proof tests. The vehicle’s heat shield tiles were intentionally removed to inspect mounting pins after cryogenic exposure, and Elon Musk indicates the catch attempt will likely occur on Flights 13–15, with Ship 40 as the leading candidate. Flight 12 will instead perform a controlled splashdown, as SpaceX avoids risking the tower on the first V3 flight, though post-splashdown explosions are expected from residual propellant igniting. Block 3 was purpose-built for the chopstick catch, with reinforced hard points and internal nose supports, while Raptor 3 engines enable the maneuver by cutting weight and adding payload. Flight 13 will likely use a high-energy suborbital trajectory to reduce heat load, with Booster 20 completing standard splashdown duties as all attention shifts to Ship 40’s historic catch attempt.

• ▶ 1:00 Ship 40, the second Block 3 Starship prototype, was fully stacked in just 114 days, highlighting SpaceX's push toward rapid, repeatable production; at over 50 meters tall and ~100 tons dry, it is designed to be the first orbital Starship caught midair by the tower's chopsticks.
• ▶ 1:47 The vehicle completed two back-to-back cryogenic proof tests in just 48 hours during a tight 5-day campaign—both the LOX and methane tanks were pressurized to verify structural integrity, with the second test finishing clean with no leaks, no deformation, and no anomalies.
• ▶ 2:24 After rolling back on May 6th, several heat shield tiles were found deliberately missing on the leeward side; this was intentional removal to inspect the pin mounting system and crunch wrap seals after extreme cryogenic exposure, revealing attachment pins, handwritten markings (SG1, BG1, BG2), and serial numbers.
• ▶ 3:34 Elon Musk posted that a Starship catch will likely happen on Flight 13 to 15, with Ship 40 considered the top candidate for the first mid-air catch by Mechazilla.
• ▶ 3:45 Flight 12 will not attempt a catch because it is the first V3 Starship flight; SpaceX won't risk tower damage from exhaust and shock waves, so it will instead perform a controlled splashdown with Ship 39.
• ▶ 5:06 Post-splashdown explosions happen because residual methane and oxygen mix after re-entry cracks tank walls or plumbing, then ignite from leftover heat or sparks—an expected testing outcome as SpaceX gathers data.
• ▶ 6:42 Starship is caught by chopsticks instead of using landing legs, eliminating massive weight and infrastructure — the core engineering logic behind the catch system.
• ▶ 7:03 Block 3 is the first Starship built from the drawing board to be caught, with purpose-built lower catch points and internal nose reinforcements, unlike earlier experimental Blocks.
• ▶ 7:46 Raptor 3 enables the catch: internalized cooling removes heavy heat shields, adding ~40 tons of payload and enabling smoother, more precise landings needed for a successful catch.
• ▶ 8:17 Flight 13 will likely use a high-energy suborbital trajectory instead of full orbit, because unfinished heat shield areas make orbital re-entry too risky—cutting plasma exposure and total heat load by roughly 30–40%.
• ▶ 9:29 The landing sequence relies on the landing flip and three or four Raptor 3 engines, which provide the precise thrust needed to hover stably between Mechazilla’s arms.
• ▶ 10:00 Mechazilla targets reinforced hard points and catch pins specifically positioned to avoid the aft flaps, requiring perfect roll control and real-time laser/camera systems to lock the ship securely without landing legs.
• ▶ 11:07 Booster 20 is in final stacking stages, with the methane downcomer already installed, but it still needs cryogenic proof testing, all 33 Raptor 3 engines, and a pad rollout.
• ▶ 11:38 B20 is slightly behind Booster 19's schedule due to process gaps, yet remains on track for Flight 13.
• ▶ 11:54 Flight 13's most likely scenario: Booster 20 performs a standard hot-staging, boost-back burn, and Indian Ocean splashdown, while all attention shifts to Ship 40 attempting the first-ever midair catch.
