SpaceX is targeting Thursday, March 30 at 7:29 a.m. PT for a Falcon 9 launch of the Space Development Agency’s Tranche 0 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. If needed, a backup opportunity is available Friday, March 31 at the same time.

The first stage booster supporting this mission previously launched one Starlink mission. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base.

The space vehicles launched during this mission will serve a part of SDA’s Proliferated Warfighter Space Architecture, a new layered network of satellites in low-Earth orbit and supporting elements that will provide global military communication and missile warning, indication, and tracking capabilities.

A live webcast of this mission will begin about 15 minutes prior to liftoff HERE

Thanks RR, link works great.

T-10:15

Webcast is going live. Wow, clear weather at V'berg!

How is the old back Rocky?

Abort at T-2 seconds. Looked like a problem with one or more engine ignition. Standing by...

Scrub for the day. They may try again tomorrow, same time.

Abort, try again tomorrow

Rocky has Spacex had an unprogrammed engine shutdown on the Falcon 9, after lift off???

I think they did have one way back when, but made up for it with a slightly longer burn of the first stage.

To allow more troubleshooting, they've now decided to wait until Saturday for their next try. No T-0 time yet announced.

Now saying Sunday at 7:27 am Pacific.

Weather looks good for a 7:29 am launch from V'Berg. WEBCAST
