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

A technology demonstration microsatellite for Astro Digital rode a Rocket Lab Electron launcher into orbit Wednesday (U.S. time) from New Zealand, setting the stage for the debut of new systems on the next Electron flight as engineers move closer to retrieving and reusing the rocket’s first stage.

The 21 satellites from York Space Systems are the first in the SDA’s Tranche 1 Transport Layer satellite constellation. SpaceX launched from pad 4 East at Vandenberg Space Force Base at 7:12 a.m. PDT (10:12 a.m. EDT / 1412 UTC).

A SpaceX Falcon Heavy rocket thundered into the sky over Florida’s Space Coast Sunday night and deployed a sophisticated internet satellite for Viasat into a circular orbit more than 20,000 miles over the equator, delivering for a competitor to SpaceX’s own Starlink broadband network.
