The Federal Aviation Administration (FAA) authorized SpaceX to fly Starship prototypes again, after the company identified the probable cause of the rocket system’s booster stage failure during a flight in May.

SpaceX said over the weekend that the next Starship flight could take place this Thursday, July 16. It would be the second release of the third version, or V3, of Starship. SpaceX also said that this Starship will carry the first third-generation Starlink satellites into space. Previously, Starship had only carried fictional versions of the largest and most powerful Internet satellites.

This is SpaceX’s second test flight of its Starship system, and its first as a public company, testing the market’s appetite for the company’s “fly, fail, repair” approach to rocket development that often ends in fireballs or, as CEO Elon Musk calls the explosions: “unscheduled rapid teardown.” SpaceX completed its initial public offering and publicly listed on the Nasdaq Stock Exchange on June 12, making it one of the top ten most valuable companies in the world and raising nearly $86 billion, a record.

SpaceX’s first test launch of the V3 Starship on May 22 was a great success. The company’s Super Heavy booster lifted the 407-foot rocket into space before the upper stage section separated and deployed 20 satellite simulators along with two modified Starlinks that recorded images of the Starship’s exterior.

The new third-generation booster was supposed to return to Earth and make a simulated landing in the Gulf of Mexico. But its engines did not restart properly and it fell into the water instead.

The problem occurred at that moment of booster separation, according to SpaceX and the FAA. SpaceX said in a post published over the weekend that “slight differences in the launch of the ship’s engine” caused the Booster to rotate 90 degrees in the wrong direction. SpaceX said it modified this engine start sequence to allow the booster to “spin more reliably in the desired direction” and that the booster was modified to “improve restart reliability.”

The FAA said in a statement Monday that the most likely causes of the Super Heavy booster failure were “heat effects on propulsion system components during the [rocket’s] ascent and engine alarm system misconfiguration.”SpaceX said in its post that it has made changes to Starship’s engine alarm and abort systems that should reduce the possibility of a similar failure in the future.

While the first Starship V3 upper stage was able to successfully deploy its test payload in May and simulate a landing in the Gulf (a milestone SpaceX had struggled to reach before), it also did so by losing one of three Raptor engines that are intended for use in the vacuum of space. SpaceX said over the weekend that it had “[s]Various operational and hardware modifications” to prevent this from happening again.

In this upcoming Starship test flight, the company will launch the first of its V3 Starlink satellites into space, which are supposed to increase the capacity of the satellite network and the speed of users. SpaceX plans to deploy 20 of these new satellites during launch. They are designed to connect to the larger Starlink constellation “via high-capacity lasers” and then burn up in the atmosphere about 20 minutes after deployment, according to SpaceX. Six of them will be equipped with cameras to photograph the exterior of Starship.

The V3 versions of Starship and Starlink are crucial to the future of SpaceX. Starlink was the only profitable part of SpaceX’s business in the run-up to its IPO, and SpaceX needs Starship to become a fully reusable rocket system to even attempt its galactic plans for space data centers and interplanetary travel.
