SpaceX was more than lucky Friday, sending its 13th full-scale Starship test flight halfway around the world from South Texas to an on-target, intact splashdown in a remote section of the Indian Ocean. Starship has made precise splashdowns before. This time, however, the ship gently tipped over and came to rest floating in a remote stretch of ocean west of Australia.
Previous splashdowns ended with conflagrations, an outcome SpaceX officials have come to expect with each water landing of Starship. The buoyant Starship looked to be in fine shape after reaching the Indian Ocean. SpaceX engineers flew drones over the vehicle to inspect its heat shield, getting their best look yet at how more than 18,000 ceramic tiles insulating the ship's stainless steel airframe weathered the trip to space and back.
The tiles withstood temperatures up to 2,600° Fahrenheit (1,430° Celsius) as Starship streaked back into the atmosphere at the end of its hour-long flight from Starbase, Texas. Encouraged by the picture-perfect end to Friday's flight, SpaceX is likely to take the next leap with Starship on the next launch, according to the company's founder and CEO, Elon Musk. That would entail hurling Starship on a longer-range trajectory, perhaps into low-Earth orbit, to bring the vehicle back to the launch site.
Mechanical arms on the launch tower will attempt to capture the ship as it slows to a hover. SpaceX has already done this with the rocket's massive Super Heavy booster, which is larger and heavier than Starship itself, but comes back at a fraction of the speed. "Unless we discover problems after mission data review, SpaceX will attempt to catch the ship with the tower on next flight," Musk wrote on X Friday evening.

SpaceX's ambition for Starship includes rapid turnarounds, and eventually multiple flights per day.
If this is to be achievable, the heat shield has to be robust against the vibrations and extreme temperatures it sees during launch and reentry. It can't be refurbished or replaced after every flight. "This is the first time we’ve put an intact Starship in the water," said Dan Huot, a SpaceX communications manager providing commentary…
