The latest prototype of SpaceX’s next-generation Starship rocket launched successfully on Tuesday but exploded on impact during an attempted landing after a development test flight.
Starship prototype Serial Number 9, or SN9, aimed to fly as high as 10 kilometers, or about 32,800 feet altitude. The flight was similar to the one SpaceX conducted in December, when it launched prototype SN8 on the highest and longest flight to date.
While the rocket flew successfully, it hit the ground explosively on its return, just as the SN8 flight did in December.
“We had, again, another great flight up … we’ve just got to work on that landing a little bit,” SpaceX principal integration engineer John Insprucker said on the company’s webcast of the flight.
The rocket prototypes are built of stainless steel, representing the early versions of the rocket that CEO Elon Musk unveiled last year. The company is developing Starship with the goal of launching cargo and as many as a 100 people at a time on missions to the moon and Mars.
Musk pivoted the company’s attention to Starship in May, after SpaceX successfully launched its first astronaut mission. He’s deemed Starship the company’s top priority, declaring last year in an email obtained by CNBC that the development program must accelerate “dramatically and immediately.”
Although Starship SN9 suffered the same explosive fate as SN8 two months ago, SpaceX views the test flight as a step forward in the rocket’s development. SN10, likely the next to attempt a launch-and-landing, was already in place when SN9 took to the skies.
“So all told, another great [flight] — and a reminder, this is a test flight, the second time we’ve launched starship in this configuration,” Insprucker said. “We’ve got a lot of good data, and [achieved] the primary objective to demonstrate control of the vehicle and the subsonic reentry.”
Musk previously said that Starship could potentially fly people in 2020, but he’s since acknowledged that the rocket still has many milestones, including “hundreds of missions,” to go before that happens.
Multiple prototypes are being built simultaneously at SpaceX’s growing facility in Boca Chica, Texas, with its SN10 rocket already rolled out to a second launchpad nearby. While SpaceX’s fleet of Falcon 9 and Falcon Heavy rockets are partially reusable, Musk’s goal is to make Starship fully reusable — envisioning a rocket that is more akin to a commercial airplane, with short turnaround times between flights where the only major cost is fuel.
