8:25am ET Update on Oct. 1: This mission is back on the pad and ready for launch after a weather delay, and contending with a crowded range. SpaceX deferred to United Launch Alliance this week while that company made two attempts to get its Delta IV Heavy booster off the pad. The second attempt was unsuccessful late on Wednesday night.
Liftoff for this Starlink mission is planned for 9:17am ET (13:17 UTC) Thursday. Weather conditions are 70-percent favorable at that time.
10:25am ET Update on Sept. 28: Monday morning’s launch attempt of the Starlink-12 mission was scrubbed in the last moments of the countdown due to thick clouds over the launch site at Kennedy Space Center. SpaceX does not have a back-up launch window for this mission because there are two launches scheduled over the next two days.
Having fixed an issue with its retraction arm at Launch Complex-37, United Launch Alliance has an opportunity to launch the NROL-44 mission on its Delta IV Heavy rocket at 12:02am ET on Tuesday (04:02 UTC). And SpaceX has the launch of a GPS III satellite planned from its other Florida launch pad on Tuesday night, at 9:55pm ET (01:55 UTC Wednesday).
Original post on Sept. 28: SpaceX returns to its launch pad at Kennedy Space Center on Monday for its twelfth launch of operational Starlink satellites. The mission is scheduled to lift off from Launch Complex-39A at 10:22am ET (14:22 UTC). Weather conditions are 70-percent favorable for liftoff.
The Starlink-12 mission will fly atop a Falcon 9 rocket first stage that previously launched the company’s first crewed Dragon mission in May, and subsequently the Anasis-II mission in July. SpaceX will attempt to recover the booster on its Of Course I Still Love You drone ship.
The mission, the company’s 11th Starlink launch in this calendar year, brings SpaceX closer to offering a public beta of its service.
It also comes as a potentially important customer, the US military, has signaled its interest in the service that provides broadband Internet from space. This week, during a roundtable with reporters, a senior Air Force official said initial tests of the Starlink system have gone well.
“What I’ve seen from Starlink has been impressive and positive,” Air Force acquisition chief William Roper said, according to Investor’s Business Daily. “They’re cleverly engineered satellites cleverly deployed. So, there’s a lot to learn from how they’re designed, and I think that there’s a lot we can learn from them.”
SpaceX has pursued a strategy of attracting both consumer customers—the company has been collecting information from those interested in the service—and institutional customers. Of those, the US military is likely the most lucrative. Roper indicated that the Air Force was willing to support efforts like Starlink that bring innovative communications services that are not otherwise available.
“We can be the stability case for companies like SpaceX and others who want to sell communications worldwide,” he said during the media roundtable. “(They) may not be thinking about customers over the ocean, but we’ve got our Navy there. (They) may not be thinking about customers up in the Arctic, but we have our airplanes there.”
A webcast for Monday’s launch attempt will begin about 15 minutes before liftoff.
