WASHINGTON — SpaceX launched a set of Starlink satellites Might 9 on a Falcon 9 whose first stage was making its tenth flight, a long-awaited aim within the firm’s reusability efforts.

The Falcon 9 lifted off from House Launch Complicated 40 at Cape Canaveral House Power Station at 2:42 a.m. Jap. The rocket’s higher stage deployed its payload of 60 Starlink satellites into low Earth orbit practically 65 minutes later.

The launch, the third in lower than two weeks for SpaceX, brings the full variety of Starlink satellites in orbit to greater than 1,550. The corporate is step by step increasing its beta check program for the broadband web service because the constellation grows. SpaceX famous on the launch webcast that it opened up that beta check program within the final week to individuals in Austria and France.

The launch itself was noteworthy because it marked the primary time a Falcon 9 first stage had flown 10 instances. The booster first launched the Demo-1 business crew check flight in March 2019. It later launched the Radarsat Constellation Mission, the SXM-7 satellite tv for pc for SiriusXM and 6 Starlink missions, most not too long ago March 14, earlier than this launch.

SpaceX had lengthy recognized 10 flights as a aim for Falcon 9 reuse in an effort to justify the numerous funding the corporate made into reusability. In latest months, although, firm executives have urged that the booster can fly greater than 10 instances.

“There doesn’t appear to be any apparent restrict to the reusability of the automobile,” Elon Musk, chief government of SpaceX, stated at an April 23 NASA press convention after the Crew-2 launch.

The corporate has been utilizing its personal Starlink missions to push the boundaries of booster reuse. That has uncovered points, akin to a February launch the place the Starlink payload reached orbit however the booster did not land. That booster was making its sixth flight, however some engine parts, akin to “boots” or covers across the engines, have been life leaders. A kind of covers had a gap that allowed scorching fuel from the engine exhaust get into different elements of the engine, triggering a shutdown that prevented the stage from touchdown.

“We do intend to fly the Falcon 9 booster till we see some form of a failure with the Starlink missions, have that be a life-leader,” Musk stated on the briefing, noting on the time {that a} tenth flight of a booster was upcoming. “We’re studying quite a lot of about reusability. It’s a tough downside for rockets.”

SpaceX has not disclosed whether or not it should try to make use of this booster for an eleventh launch, however the profitable touchdown at the very least preserves that risk. “This booster will get to stay once more,” Michael Andrews, the host of the SpaceX launch webcast, stated shortly after the touchdown.
