SpaceX moves Booster 19 to Pad 2 May 18

SpaceX moved Super Heavy Booster 19 from Mega Bay 1 to Pad 2 at Starbase on May 18, according to NASASpaceflight, in the latest visible step toward the company’s next Starship test flight. The move positions the booster at the launch site that SpaceX plans to use for Flight 12, the first flight of its upgraded Version 3 Starship system. SpaceX says the mission is preparing to launch as soon as Wednesday, May 20, with the launch window opening at 5:30 p.m. Central Time. The company has paired Booster 19 with Ship 39 for the test. ### Why was Booster 19 moved back to Pad 2 now? May 18 was the date NASASpaceflight said Booster 19 rolled from Mega Bay 1 to Pad 2, a transfer that follows earlier booster work at the pad and in the bay. NASASpaceflight reported on May 8 that Booster 19 had already completed a full-duration, full-thrust static fire on May 7 before Ship 39 joined it for a wet dress rehearsal campaign. (nasaspaceflight.com) March 18 was the date NASASpaceflight said Booster 19 completed an initial test campaign on the newly commissioned Pad 2 before returning to Mega Bay 1. That earlier round of work means the latest move is part of a repeated flow between production, testing and launch infrastructure rather than a first-time pad arrival.

Flight 12 will be the first launch of Starship Version 3 hardware and the first launch from Pad 2, according to SpaceX and Spaceflight Now. SpaceX says the flight will debut the next generation of Starship and Super Heavy vehicles, powered by the next evolution of the Raptor engine and launched from a newly designed pad at Starbase. (nasaspaceflight.com) Booster 19 and Ship 39 are the target stack for that mission, NASASpaceflight reported on May 1. NASASpaceflight said the launch would use Orbital Launch Pad 2 at Starbase in Boca Chica, Texas, and described the timeline as aggressive as engineers worked through remaining milestones on both the vehicle and the pad. (spacex.com) ### What will SpaceX try to do on this mission? SpaceX says the booster’s primary objectives are launch, ascent, stage separation, a boostback burn and a landing burn toward an offshore landing point in the Gulf. Because this is the first flight test of what SpaceX calls a significantly redesigned vehicle, the company says Booster 19 will not attempt a return to the launch site for catch. (nasaspaceflight.com) Ship 39 is set to target multiple in-space and reentry objectives, according to SpaceX, including deployment of 20 Starlink simulators and two modified satellites meant to test hardware planned for Starlink V3. SpaceX also says the ship will attempt an in-space relight of a single Raptor engine and additional heat-shield and flap stress objectives during reentry.

Pad 2 has been under construction for about 22 months, NASASpaceflight reported in March, and the outlet said the site is intended to support the next chapter of the Starship program. NASASpaceflight described Booster 19’s earlier March rollout as the start of pad commissioning and booster engine testing for Block 3 hardware. (spacex.com) May 12 was the date Spaceflight Now reported that Flight 12 would be the first launch from Pad 2, which it described as updated launch infrastructure supporting both launch and catch capabilities. That makes the May 18 booster move part of final site-side preparations as well as vehicle staging. (nasaspaceflight.com) ### What happens next, and when can people watch? Wednesday, May 20 is the earliest launch date now listed by SpaceX for Flight 12, with a 5:30 p.m. Central Time window opening. SpaceX says its live webcast will begin about 45 minutes before liftoff and will be available on its website and X account. The next named participants in the test are Booster 19 and Ship 39, which SpaceX says will fly together on the twelfth Starship flight test from Starbase’s Pad 2.
