Live coverage: Soyuz soars into space on its fourth launch attempt

The first flight of an experimental U.S. military rocket designed for low-cost, quick-reaction satellite launches ended in failure over Hawaii on Tuesday, the Air Force said, destroying 13 small research spacecraft clustered on the mission for NASA researchers and university students.

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).

A commercial Cygnus supply ship left the International Space Station on Monday after delivering more than 5,000 pounds of cargo and experiments, ready to start a week of standalone operations to include a groundbreaking microgravity fire experiment and deployment of four commercial weather-monitoring CubeSats in orbit.
