This mission, the rocket's 14th test flight, also marked the first time that Starship deployed Starlink internet satellites into the existing larger constellation: 26 new next-generation nodes in total.
But not all went as planned. An engine went out, though SpaceX quickly determined Starship could still reach orbit without it. While SpaceX had planned for Starship to orbit Earth six times, it changed gears and had Starship return after only two orbits.
And the splashdown in the Pacific Ocean ended in a huge bang, rather than the soft landing the company had hoped for. This flight can still be viewed as a success. It was an important step toward putting the enormous rocket to work by sending it into orbit.
Starship is a key part of SpaceX's vision. The company wants Starship to be a fully and rapidly reusable transport system that slashes the cost of spaceflight. To realize this vision of extremely low-cost launches, SpaceX needs to be able to bring these spacecraft back from orbit, refurbish them and launch them again in short order.
Whether that all becomes quick and routine largely depends on dark ceramic tiles covering Starship's underside. These tiles make up Starship's heat shield. I'm an engineer and professor who has researched the way heat shields respond when reentering the atmosphere, a process that is extremely harsh on a spacecraft.
I see Starship's heat shield as a technical challenge that also drives the company's economics. A spacecraft that survives its return has passed an essential test. Next, engineers must establish how much work it will take to repair or replace the heat shield before its next launch.
