Space Development Agency's Tranche 0 Mission
SpaceX is targeting Friday, March 31 at 7:29 a.m. PT (14:29 UTC) 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. 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.
