Starship Ship 40 Returns to Starbase After Ocean Recovery

A flown Starship is back in Texas

Ship 40 is the first Starship upper stage to return to its launch site after flying in space. It is standing upright inside the Megabay hangar at Starbase, SpaceX's South Texas facility, next to three newer ships that are still being assembled.12 SpaceX announced the return on October 13. The company said the vehicle will give it first-of-its-kind data on a heat shield, Raptor engines and avionics that have actually flown.48

Ship 40 did not fly itself home. SpaceX has caught three Super Heavy boosters with the "chopstick" arms on its launch tower, but no upper stage has yet returned to Starbase under its own power.1 Ship 40 came back by tugboat, by heavy-lift ship and by road. Even so, it is the first time SpaceX engineers can study a Starship upper stage from top to bottom after it went through launch, reentry and splashdown. In my view, that matters more for SpaceX's reusability plans than any single flight this year.

How Flight 13 produced a survivor

Ship 40 launched on July 24 on top of Super Heavy Booster 20, on Starship's 13th flight test. It flew a suborbital path and made a controlled splashdown in the Indian Ocean.1 Every earlier ship that reached the water had exploded after tipping over. Ship 40 tipped over as planned but stayed mostly intact and afloat.110 Florida Today described the end of the flight as a few flames and no explosion, with the ship bobbing in the sea.7

The booster did worse that day. During its landing attempt, Booster 20 lit only 10 of its planned 13 engines, lost five more, and hit the water at high speed.10 Flight 13 also carried the first Starlink V3 satellites. They followed the ship's trajectory and burned up in the atmosphere after testing, as planned.10

An improvised recovery

SpaceX had not planned to bring the ship home. Coverage agrees that the company put together a recovery effort quickly, while saying it did not expect to get the vehicle back. Elon Musk said at one point that the effort was "not looking good."7 Crews towed the 171-foot (52-meter) stage through rough seas for 24 days. They reached the waters off Australia's Christmas Island in August, and Florida Today put the sighting there at August 18.17

In calmer water off Christmas Island, engineers inspected the ship and took heat shield samples from its underside. Ship 40 was then loaded onto Forte, a large semi-submersible transport ship, for the trip to Texas.18 The San Antonio Express-News described that trip as a five-week voyage. Forte reached the Port of Brownsville on October 7, where local space fans and photographers gathered to watch it arrive.37 From there the ship went by road to Starbase, was turned upright outside the Megabay and moved inside.1

Reports differ a little on how long all this took. Space.com called it "nearly three months" in one place and "more than two months" in another. Notebookcheck said it was close to three months.18 From the July 24 launch to the October 13 announcement is about 11.5 weeks, so "nearly three months" fits best. The difference does not matter much. What stands out is that the trip home took far longer than the flight.

Why an expensive salvage matters

The Express-News pointed out that SpaceX has not said what it will do with Ship 40.3 What the company has said is that the ship is mainly a source of data, and the reporting agrees on that.47 The heat shield is the key part. Making Starship's thermal protection quick to reuse is probably the hardest problem left in fully reusing the rocket. Until now, SpaceX could only look at a flown heat shield in photos or by sampling tiles at sea. It can now examine a whole one.

SpaceX is already treating heat shield inspection as part of how it flies. On Flight 14, three of the Starlink V3 satellites carried cameras to scan the ship's heat shield and send the images to operators. The goal was to test ways of judging whether the shield is ready for future returns to the launch site.18 A complete, recovered ship gives SpaceX something to check those camera images against. If the photos taken in orbit match what engineers find on Ship 40's tiles, SpaceX can be more confident when deciding whether a ship is safe to bring back to the tower.

That decision is coming soon. Musk has said Flight 15 could include the first attempt to catch a returning upper stage with the tower arms, if the vehicle meets the conditions for a safe return.18 Ship 40 is unlikely to change hardware already built for that flight. It could, however, shape how SpaceX decides whether to try the catch or send the ship to the ocean instead.

Orbit and Starlink V3

Ship 40's return comes right after the bigger milestone of SpaceX's year. On September 28, Flight 14 sent Ship 41 into orbit for the first time and carried Starship's first working payload: 26 Starlink V3 satellites.110 Ars Technica noted that earlier flights had come within about 99 percent of orbital speed. SpaceX had held back because of concerns about stranding such a large vehicle in orbit.14

The flight was not clean. One of Ship 41's Raptor engines shut down early during ascent. SpaceX went ahead with the orbital insertion only after confirming the ship had enough backup capability, then cut a planned 10-hour mission to about three hours.1418 The ship splashed down north of Hawaii and, like every ship except Ship 40, exploded on impact.314

The satellites matter most for SpaceX's business. Each Starlink V3 satellite is rated at 1 Tbps of capacity, so this one launch added about 26 Tbps, roughly ten times what a Falcon 9 launch of V2 Mini satellites delivers.18 Ars called the deployment the step that opens up major growth for Starlink. The V3 satellites are too big to fit on Falcon 9 and were released one at a time through a dispenser in Starship's cargo bay.14 Space.com reports that most future Starship launches would go toward a next-generation Starlink network of about 100,000 satellites and "Starmind," an AI data center constellation that Musk says would have a million spacecraft.19 Planned constellations on that scale depend on cheap launches, which in turn depend on recovering and reusing ships like Ship 40.

Florida and the Moon

SpaceX is getting ready to fly Starship from more than one site. Julianna Scheiman, who directs SpaceX's NASA science and Dragon programs, said in early October that construction at Kennedy Space Center's Pad 39A is mostly finished and the pad is moving into acceptance and activation testing.19 She said at least one more Starship flight will launch from Starbase before the first launch from Florida.19 Reports have mentioned December 10 as a possible first Florida launch date, but SpaceX has not confirmed any date.15

The Florida work is tied to NASA's Moon program. According to Space.com, Starship's first Artemis flight is Artemis III, planned for 2027 as a docking test in Earth orbit between the ship and NASA's Orion capsule, and that launch will come from Pad 39A.19 Space.com also cautioned that Starship still has to show major capabilities, especially transferring propellant between ships in orbit, before it can fly full missions to the Moon or Mars.13 With no propellant transfer test done yet, the late-2026 Mars launch window is no longer realistic. Musk had once put the odds of using it at "50/50."13

Reports differ on the schedule

The biggest disagreement in the coverage is about when Flight 15 will happen. Planning documents cited on October 7 listed October 19 and October 30 as "no earlier than" dates for Flights 15 and 16.19 One week later, Space.com reported that both had apparently slipped to mid-to-late November, with no firm date confirmed publicly.13 The Express-News said only that another flight is expected before the end of the year.3 Ship 42 and Booster 22 are listed for Flight 15. Ship 42 completed a cryogenic test on October 9.1112

The later dates look more realistic to me. Boosters failed their landings on both Flight 12 and Flight 13, and Flight 14 lost a ship engine during ascent.10 A team planning its first upper-stage catch has good reason to take extra time, and SpaceX now has a recovered ship to study first.

The takeaway

Ship 40's return is not the reusability milestone SpaceX wants. That would be a ship flying back and being caught at the tower. What Ship 40 offers is something no previous flight could: a complete, flown upper stage to take apart and inspect. Coming two weeks after Starship's first orbital flight and first working Starlink deployment, it suggests the program is moving from proving the rocket can fly to proving it can be reused. Whether that holds up will depend on the next one or two flights.
