SpaceX has landed on the West Coast for the first time [Updated]

A view of the Falcon 9 rocket on Sunday morning, ready for launch.

10:35pm ET Update: On Sunday night, SpaceX’s Falcon 9 rocket took off as scheduled and ascended into space. After about three minutes, the second stage carried its payload onward, toward a successful deployment of the SAOCOM 1A satellite into a Sun-synchronous orbit.

After it separated from the second stage, the first stage of the Falcon 9 rocket arrested its forward movement and began falling back toward Earth. It, too, found success in landing at a new site north of Los Angeles. This marked the first time a Falcon 9 rocket has landed on the West Coast and was SpaceX’s 30th landing of a first stage, overall.

Ars had photographer Trevor Mahlmann on site for the historic landing, and we will post his photographs after he collects his remote cameras.

Original post: The US Air Force has a message for residents of Santa Barbara, Ventura, and San Luis Obispo counties—do not be alarmed on Sunday night around 7:30pm local time if you hear a loud noise. That’s just the sonic boom of a rocket’s first stage returning from space and landing for the first time, ever, at a site along the West Coast of California.

On Sunday night, SpaceX is scheduled to launch a Falcon 9 rocket from Vandenberg Air Force Base in California, which is a couple of hours north of Los Angeles. While the company has landed several first-stage boosters on a drone ship offshore from California, until now it has not attempted to land at a site along the coast. But now it has completed the “Landing Zone 4” facility and received the necessary federal approvals for rockets to make a vertical landing there.

For long-time employees of the Hawthorne, California-based company, there must be some satisfaction in this. More than a decade ago, when SpaceX sought to begin launching its Falcon 1 rocket, the company asked the Air Force for permission to launch from Vandenberg. But the military and some of the companies using the facility to launch national security missions, including Lockheed Martin and Boeing, looked coolly upon the request from SpaceX. Now SpaceX has built a landing zone on the former site of Space Launch Complex 4W, where Titan rockets built by Lockheed were previously launched.

This will be SpaceX’s 17th launch attempt this year, bringing the company close to tying its record-setting pace of 18 launches last year. With as many as a half-dozen launch attempts left this year, SpaceX should easily surpass its 2017 total, barring a major accident.

This Block 5 first stage of the Falcon 9 rocket has previously flown once before, launching 10 Iridium NEXT satellites into a polar orbit 625km above the Earth. It returned to a drone ship off the West Coast after that flight. The payload launching Sunday night, the SAOCOM 1A satellite for Argentina’s Space Agency, weighs less than a lot of the Falcon 9 payloads launched into a Sun-synchronous orbit several hundred kilometers above the Earth. Therefore, the first stage will have ample fuel to return to the new coastal landing site.

SpaceX is also likely to try to retrieve one-half of the Falcon 9 rocket’s payload fairing. It has come close to catching these before with its large, catcher’s-mitt shaped net attached to a boat, but it has yet to succeed. (Update: There will be no payload fairing recovery attempt per the SpaceX webcast.)

For Sunday night’s attempt, the instantaneous launch window opens at 7:21pm PT (02:21 UTC on Monday). The landing (and sonic booms) should occur less than eight minutes later. A back-up launch window is available on Thursday night at the same time. The webcast below should begin about 15 minutes before the window opens Sunday night.
