Spacex Will Attempt to Make a Historic West Coast Landing Sunday Night:

This will be SpaceX's 17th launch attempt this year.

[...] 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.

[...] This will be SpaceX's 17^th launch attempt this year, bringing the company close to tying its record-setting pace of 18 launches last year. With as many as half a 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 and 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.

SpaceFlightNow reports:

Launch time: Approx. 0221 GMT on 8th (10:22 p.m. EDT; 7:22 p.m. PDT on 7th)
Launch site: SLC-4E, Vandenberg Air Force Base, California
A SpaceX Falcon 9 rocket will launch the SAOCOM 1A for CONAE, Argentina's space agency. SAOCOM 1A is the first of two SAOCOM 1-series Earth observation satellites designed to provide radar imagery to help emergency responders and monitor the environment, including the collection of soil moisture measurements.

Launch will be live streamed on YouTube starting approximately 15 minutes before launch. Backup launch time is on Thursday.
