Video: 4K video replay of SpaceX’s CRS-21 launch (members only)

A full-size prototype of SpaceX’s heavy-lift Starship launch vehicle soared high into the atmosphere Wednesday in a spectacular test flight over South Texas, and successfully guided itself to a beachside landing site before exploding at touchdown. Elon Musk, SpaceX’s founder and CEO, hailed the nearly seven-minute test flight as a success.

The booster will first launch the Starlink 10-5 mission no earlier than the morning of Tuesday, Aug. 20. The static fire test happened Monday evening shortly after 7 p.m. EDT (2300 UTC).

The mission comes as SpaceX is preparing for a week that includes a rideshare flight; a dual-manifest, Moon bound missions; and Starship Flight 7. Liftoff from pad 40 at Cape Canaveral Space Force Station is set for 11:47 a.m. EST (1647 UTC).
