The first-stage booster has returned to Earth and landed on the Of Course I Still Love You droneship stationed in the Pacific Ocean.

Update, 2:42 p.m.:

The Falcon 9 rocket lifted off just after 2:41 p.m., spiraling into the sky and leaving a plume of smoke in its wake as it travels into space to deliver the satellites into orbit.

Update, 2:40 p.m.:

A SpaceX representative hosting the livestream of the rocket launch said all signs are pointing toward a launch today.

She said there is only a 20% chance of negative conditions that might cancel liftoff.

Liftoff is expected in roughly one minute.

Original story:

A SpaceX rocket is expected to launch from Vandenberg Space Force Base on Friday afternoon, carrying 46 of the aerospace company’s Starlink satellites into orbit.

The launch is scheduled for 2:40 p.m., with a backup opportunity on Saturday at 10:40 p.m., according to SpaceX.

The company tweeted at 2 p.m. that crews were “keeping an eye on upper-level winds” that might disrupt the launch.

An online broadcast is expected to go live about five minutes prior to liftoff. That can be watched at spacex.com/launches/sl3-3.

The launch will use the company’s Falcon 9 rocket; the first-stage booster that will be used previously launched the Crew-1, Crew-2, SXM-8, CRS-23, IXPE, Transporter-4, Transporter-5, Globalstar FM15, and one other Starlink mission, according to SpaceX.

Following separation, the Falcon 9’s first stage will return to Earth and land on the Of Course I Still Love You droneship stationed in the Pacific Ocean.
