SpaceX Starship Flight Test 2026: What Success Would Unlock

The most recent SpaceX Starship flight test, Flight 13, lifted off from Starbase, Texas, on July 24, 2026, after two scrubbed attempts, and delivered SpaceX’s most complete demonstration yet of the redesigned Starship Version 3 vehicle, deploying operational satellites for the first time, executing an in-space engine relight, and achieving what SpaceX described as the softest splashdown of any Starship upper stage to date. The booster’s own landing attempt ended in a hard impact in the Gulf of Mexico, a reminder that even a mostly successful flight still leaves real engineering problems to solve before Starship can support NASA’s Artemis moon missions.

What Happened During Flight 13

Booster 20 and Ship 40 lifted off from SpaceX’s Pad 2 at Starbase at 5:51 p.m. CDT on July 24, with all 33 Raptor engines running through ascent. The vehicle passed through maximum aerodynamic stress, or Max Q, roughly 58 seconds into flight, followed by booster engine cutoff at 2 minutes 18 seconds and hot-staging separation three seconds later, when Ship 40’s engines ignited while still attached to the Super Heavy booster. The booster then performed a boostback burn to reverse its trajectory toward the Gulf of Mexico, while Ship 40 continued toward its suborbital trajectory. At roughly 16 minutes 40 seconds into the flight, Ship 40 began deploying 20 Starlink V3 satellites, the first time this next-generation satellite design had flown and the first time any Starship flight had deployed operational, functioning satellites rather than mass simulators. Around 39 minutes into the mission, Ship 40 conducted an in-space relight of one of its Raptor engines, a capability SpaceX says is required for any future Starship mission that refuels or maneuvers in orbit. The vehicle then reentered the atmosphere, testing new load-sensing heat shield tiles, before executing a landing flip and a controlled splashdown in the Indian Ocean at roughly 1 hour 5 minutes after liftoff, remaining upright and intact in the water afterward, a first for the vehicle.

The Booster’s Rough Landing

Super Heavy Booster 20 did not fare as well. After separating from the ship and completing its boostback burn, the booster attempted a landing burn in the Gulf of Mexico using 13 of its Raptor engines, but only 10 successfully relit, and additional engine shutdowns followed, causing the booster to strike the water hard rather than complete the soft, controlled splashdown SpaceX had targeted. It was a partial repeat of the problems seen on the debut flight of the Version 3 vehicle in May 2026, when the booster also missed its landing target after engine issues during descent, underscoring that while SpaceX has made real progress with the upper stage, booster reliability during the landing burn remains an unresolved engineering challenge for the V3 design.

Two Scrubs and an Abort Before Liftoff

Flight 13 almost did not fly on schedule at all. SpaceX first attempted the launch on July 16, but the flight computer triggered an automatic abort at T-minus zero, just after engine ignition, when several of the Super Heavy booster’s 33 Raptor engines failed to ignite properly because of problems with their liquid oxygen turbopumps. SpaceX destacked both Ship 40 and Booster 20 for inspection and replaced the affected engines, testing them on the pad on July 22; one of the removed engines was separately test-fired at the company’s McGregor, Texas facility and completed a full-duration ascent burn. A second launch attempt, initially targeted for July 23, was pushed back a day due to Tropical Storm Bertha and low cloud cover that would have prevented SpaceX from imaging the vehicle during ascent, before the flight finally launched successfully on July 24.

Why This Test Matters for Artemis

The stakes extend well beyond SpaceX’s own launch cadence. NASA has restructured its Artemis III mission so that, rather than immediately landing on the moon, a crew will first orbit at high altitude while Orion performs rendezvous and docking tests with both SpaceX’s Starship Human Landing System and Blue Origin’s Blue Moon lander, a mission architecture that depends directly on the same V3 hardware and in-space relight capability demonstrated on Flight 13. Under the current schedule, Artemis III is targeted for 2027, while the first crewed lunar landing has been pushed to Artemis IV, no earlier than 2028, a timeline that assumes Starship can reliably demonstrate orbital flight, in-orbit refueling and eventually a full booster catch at the launch tower, none of which has yet been achieved.

What Comes Next

SpaceX has signaled that Flight 13’s mostly successful outcome clears the way for more ambitious tests. Elon Musk said shortly after the flight that Flight 14 would attempt to catch the Starship booster using the Mechazilla launch tower arms, though that maneuver requires the vehicle to have reached orbit first, something no Starship flight has yet accomplished. SpaceX President Gwynne Shotwell said in a June interview that, assuming Flight 13 went well, the company might attempt its first fully orbital Starship mission on Flight 14, potentially followed by the vehicle’s first launch from a new pad in Florida on Flight 15. SpaceX did not immediately confirm a firm date for Flight 14 following the July 24 launch.

Limitations

Some technical details of Flight 13, including the exact number of Raptor engines that failed during the July 16 abort attempt, have been reported inconsistently across outlets, with some accounts citing four engines and others citing six. SpaceX has not published a detailed post-flight report explaining precisely why the Super Heavy booster’s landing burn engines failed to fully relight, so the account here relies on preliminary reporting rather than an official failure investigation. Timelines for Flight 14, an eventual booster catch, and orbital flight are based on statements from SpaceX executives rather than confirmed launch dates, and have shifted before in the Starship program’s history.

FAQ

What did SpaceX accomplish during the July 2026 Starship flight test?

Flight 13, launched July 24, 2026, deployed 20 operational Starlink V3 satellites for the first time, performed a successful in-space Raptor engine relight, and achieved a soft, upright splashdown of the Starship upper stage in the Indian Ocean, though the Super Heavy booster suffered a hard impact during its own landing attempt.

Why was the Starship flight test delayed twice before launching?

An initial July 16 attempt was aborted at the last second when several of the booster’s 33 Raptor engines failed to ignite due to turbopump issues, and a subsequent attempt was pushed back a day because of Tropical Storm Bertha and cloud cover.

How does this SpaceX Starship flight test relate to NASA’s Artemis program?

NASA’s restructured Artemis III mission requires Orion to dock with Starship’s lunar lander variant in orbit, a maneuver that depends on capabilities like in-space engine relight demonstrated on Flight 13, making this test a direct precursor to Artemis milestones targeted for 2027 and 2028.

What will SpaceX attempt on the next Starship flight?

SpaceX has said Flight 14 could attempt the company’s first fully orbital Starship mission, a prerequisite for an eventual booster catch at the launch tower using the Mechazilla arms, a maneuver Elon Musk has said SpaceX intends to try once Starship reaches orbit.

Bottom Line

The July 2026 SpaceX Starship flight test showed a vehicle capable of hitting nearly every milestone that matters for NASA’s moon ambitions, deploying satellites, relighting an engine in space, and surviving reentry and splashdown intact, even as its booster’s landing burn remains a persistent weak point. With Artemis III’s revised timeline for 2027 and a crewed lunar landing not expected until Artemis IV in 2028, how quickly SpaceX can now push toward orbital flight and a full booster catch will determine whether that schedule holds.
