Live coverage: Soyuz test flight concludes with landing in Kazakhstan

With its payload shroud filled with multiple U.S. Air Force satellites heading for a high-altitude perch over the equator, a United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral Saturday at 7:13 p.m. EDT (2313 GMT) in its most powerful configuration with five strap-on solid-fueled boosters.

Watch a replay of the Falcon 9 rocket’s liftoff from Cape Canaveral Air Force Station as seen from the Kennedy Space Center press site roughly 4 miles away.

The first Ariane 5 launch since a mission flew off course Jan. 25, deploying two communications satellites into an off-target orbit, is underway. Liftoff with the DSN 1/Superbird 8 and Hylas 4 communications satellites occurred on time at 2134 GMT (5:34 p.m. EDT).
