SpaceX completed the 13th integrated test of its Starship megarocket on July 24, flying the upgraded V3 prototype and recording a string of technical wins: the Super Heavy booster and the upper Starship spacecraft both performed controlled splashdowns, the ship successfully relit an engine in space, and 20 Starlink V3 test satellites were deployed and contacted by the company.
The mission matters because it demonstrates progress on the vehicle behaviours SpaceX must master — engine relights, heat‑shield survival and stage recovery — milestones that affect commercial heavy‑lift customers and NASA’s timeline for a crewed lunar test flight.
Flight 13: V3 completed with controlled splashdowns and test deployments
SpaceX said Flight 13 separated the two stages roughly two minutes after liftoff. The Super Heavy booster ignited all 33 engines at liftoff and used 13 engines as planned for a boostback relight. The booster made a controlled splashdown in the Gulf of Mexico; SpaceX spokesperson Dan Huot noted the landing velocity was “a little bit high” and that not all 13 engines relit on the landing burn.
The upper Starship spacecraft completed its planned engine burns, successfully reignited one engine in vacuum and completed a controlled splashdown in the Indian Ocean roughly an hour after liftoff. Huot called the touchdown a “dream scenario” and dubbed the mission “Lucky Number 13.”
During a coast phase, Starship released 20 Starlink V3 test satellites from a side ejection slit. SpaceX confirmed on X that it established contact with all 20 satellites; the company said these satellites were on a suborbital trajectory and were expected to burn up about 20 minutes after deployment. Six of the satellites carried cameras configured to image Starship’s heat shield during the pass.
How V3 behaved: staging, relights, heat shield and deployments
The flight executed a hot‑staging separation: after the booster performed main engine cutoff (MECO), the upper ship ignited its engines to pull away. Max Q on ascent was higher than in previous flights because the team deliberately pushed to a “higher dynamic pressure” profile to save fuel and increase payload potential.
Key technical items tested were engine relights and heat‑shield performance. Starship V3 successfully relit one of its six sea‑level engines in vacuum — an ability SpaceX has previously demonstrated on other flights but failed to complete on the prior V3 run in May. The company has also been studying the ceramic hexagonal tiles that make up Starship’s heat shield; visual monitoring from ground cameras and the test‑satellite cameras played a role in assessing tile performance across ascent and reentry.
The Starlink V3 deployment used a narrow side slit that ejects satellites folded flat; the test satellites briefly deployed solar arrays and attempted laser links before their planned reentry. SpaceX said it made contact with each satellite during their short lives.
Why this flight matters to customers and NASA
The confirmed relights, improved heat‑shield imagery and controlled splashdowns are tangible steps toward SpaceX’s goals for routine heavy‑lift launches and stage reuse. For customers that need high mass-to-orbit capability, demonstrable progress on engine reliability and payload‑handling methods is essential before operational missions are accepted.
Flight 13 also has direct implications for NASA. The agency is counting on Starship for a crewed lunar test flight as soon as 2028; SpaceX still must demonstrate orbital insertion, on‑orbit refueling and safe reentry profiles before astronauts can fly. The flight’s successful relight and heat‑shield observations reduce some technical uncertainty, but they do not yet close the remaining requirements NASA will demand for crewed missions.
Context and implications for reusability and launch cadence
Flight 13 was the second test for the V3 configuration; the first V3 attempt in May experienced multiple engine outages. SpaceX replaced six engines on the vehicle ahead of this launch after a prior abort where moisture likely prevented several engines from igniting. The relative smoothness of Flight 13 suggests improved ground‑handling and ignition reliability for this hardware set.
The team deliberately pushed a higher‑dynamic‑pressure ascent to conserve fuel and increase potential payload mass to orbit. That choice trades increased structural and thermal stress against improved payload performance; the company monitored the heat shield closely and used cameras and test satellites to gather data.
Recovery strategy also remains iterative. Super Heavy’s controlled splashdown — with some engines failing to relight for the final burn and a higher than planned touchdown velocity — indicates the booster is closer to repeatable behaviour but not yet recoverable to dry land. SpaceX has said ocean recovery is an intended step in the campaign.
What to watch next
Significant unknowns remain. SpaceX must demonstrate orbital entry and on‑orbit refueling to meet the requirements for crewed lunar missions. Future flights will indicate whether V3 can reliably relight multiple engines in vacuum and execute repeatable booster recovery burns for dry‑land or surface return. Observers should track whether upcoming missions convert suborbital Starlink deployments into operational orbital deliveries and whether the company shifts recovery objectives from controlled splashdowns to intact landings.
There is also market and regulatory attention: this was SpaceX’s first Starship flight since the company became publicly traded, and the prior aborted attempt contributed to a selloff that left shares below the IPO price — a factor investors will watch as technical milestones accumulate.
Flight 13 advanced several measurable technical points for Starship V3, but orbital insertion, refueling and crewed‑flight validations remain to be proven.
