Starship flight 15 catch set for 4:17 p.m. ET: what to watch

The Ship catch is planned for roughly 22 and a half hours after Friday’s liftoff, around 4:17 p.m. ET Saturday. SpaceX has said the whole mission should last 22 hours and 33 minutes if everything goes to plan.

It is far from locked in. SpaceX built three checkpoints into the flight where controllers can choose an early return to the Pacific Ocean instead of coming home to Texas:

• about 10 minutes after the Starlink satellites finished deploying;
• at 7 hours and 15 minutes into the flight;
• at 20 hours and 41 minutes, the last chance before the trip home is committed.

If the Ship passes all three, it fires its engines for about 10 seconds at roughly 21 hours and 36 minutes after launch. That deorbit burn points it back toward South Texas, and it hits the thick part of the atmosphere around 35 minutes later. Even on final approach there is a way out: SpaceX has marked off a backup splashdown zone in the Gulf of Mexico in case conditions near the tower aren’t safe.

In its mission description, SpaceX said Starship will only come back to the launch site if the flight team has confirmed that the systems needed for reentry, the final landing burn and the approach to the tower are all healthy.

The booster was supposed to fly back and be grabbed by the tower’s giant mechanical arms, nicknamed the chopsticks, about six and a half minutes after launch. Instead, SpaceX called off the attempt and sent it into the Gulf of Mexico, where it hit the water in a huge explosion that observers more than 10 miles away could see.

SpaceX hasn’t given a detailed reason. One account of the flight points to trouble with some of the booster’s engines, while others describe the cause as unspecified or not yet clear. Until SpaceX explains, treat the engine explanation as a report rather than a confirmed finding.

The miss stings because this booster is the newest Version 3 design, which SpaceX started flying earlier this year. No V3 Super Heavy has been recovered yet. The company did catch and recover three boosters of the original V1 design and flew two of them again, so the tower catch itself is proven. Getting the bigger V3 to repeat it is the open problem.

Everything else on the way up went smoothly. The booster’s 33 Raptor 3 engines produced more than 18 million pounds of thrust, the stages separated about two and a half minutes after liftoff, and the launch happened right on time at 5:47 p.m. ET Friday.

Flight 15 is already Starship’s longest trip to space. Here is how it stacks up against the previous flight:

• Orbit: both flights reached orbit. Flight 14, launched Sept. 28, was the first; this is the second. Ship 42 settled into a low orbit about 170 miles (275 kilometers) up, 26 minutes and 10 seconds after liftoff.
• Time in space: Flight 14 ran a little over three hours after an engine problem cut it short, well under the nine-plus hours SpaceX had hoped for. Flight 15 is planned to circle Earth 14 times over more than 21 hours.
• Landing: Flight 14’s Ship came down in the Pacific Ocean. Flight 15 is aiming for a tower catch on land, which has never been attempted with an upper stage.
• Payload: both flights carried 26 of the larger Starlink V3 satellites, making this the second V3 batch in orbit.

SpaceX’s Dan Huot called the orbit insertion a really great moment on Friday’s launch webcast, noting that Starship was in orbit around Earth for only the second time.

The biggest question for the Ship is whether its heat shield survived the climb in good shape. The shield is a skin of hexagonal ceramic tiles that has to protect the vehicle as it slams back into the atmosphere at speeds that may top 17,600 miles per hour.

SpaceX came up with a clever way to check it. Three of the 26 Starlink satellites carried cameras, pointed back at the Ship as they slid out of its cargo door, to photograph the tiles and other hardware. Engineers then spent a few hours going through those images along with footage from ground tracking cameras.

The early verdict was good. Huot said the heat shield team confirmed the shield was in a good posture for reentry and a return to the launch site. That’s the clearest sign so far that SpaceX still means to go for the catch.

Most people will never ride a Starship, but you may feel the results. The rocket’s main near-term job is launching Starlink satellites, and each V3 is far more capable than the older V2 models, of which more than 11,000 are already in orbit. SpaceX says this one batch adds a terabit of data capacity to the network, about the same as 10 Falcon 9 launches of V2 satellites.

Reuse is what makes that affordable. Elon Musk has said full and rapid reuse could cut the cost of reaching orbit by a factor of 100 or more. SpaceX itself calls catching both stages the holy grail of rocketry. For comparison, NASA’s Space Shuttle was partly reusable but needed weeks of refurbishment between flights.

The stakes for spaceflight are just as big. NASA picked Starship as one of the landers for its Artemis Moon program, which aims to return astronauts to the lunar surface before the end of 2028. First, a Starship is meant to meet and dock with NASA’s Orion capsule and the Artemis III crew in Earth orbit in summer 2027, alongside a test version of Blue Origin’s Blue Moon Mark 2 lander.

Even a perfect catch wouldn’t finish the job. SpaceX still has to show it can turn a booster and a Ship around quickly and fly them again. Musk has projected about one Starship launch a week during the first half of 2027, and he has said SpaceX is targeting 10,000 Starship launches a year by 2030.

The Moon missions add another hurdle: refueling in space. A lunar Starship needs more propellant for a round trip than a single launch can carry, so SpaceX will have to transfer fuel between vehicles in orbit on future flights. And the booster catch has to work reliably on the V3 design, which Friday showed it doesn’t yet.

For now, the countdown that matters is Saturday’s. Watch for the final checkpoint, 20 hours and 41 minutes into the flight. If SpaceX keeps going past it, Ship 42 is coming home to Texas.
