Live coverage: Delta 2 launches

A Russian-built Soyuz booster lifted off Friday from the European-run spaceport in French Guiana, carrying four new broadband Internet satellites to orbit to join the O3b network owned by SES. Launch occurred at 1710:06 GMT (12:10:06 p.m. EST).

United Launch Alliance and SpaceX recently won contracts worth $739 million to send six missions into orbit for the U.S. military, and the Air Force has announced a new title for its flagship launcher program, dropping “expendable” from the name in a new era of reusable rockets.

SpaceX scrubbed the planned launch of its next set of Starlink satellites Friday. A Falcon 9 rocket is awaiting liftoff from pad 39A at the Kennedy Space Center in Florida with 57 Starlink Internet satellites and two commercial Earth-imaging microsatellites for BlackSky.
