Live coverage: Soyuz crew lands in Kazakhstan

Two pilots aboard Virgin Galactic’s commercial SpaceShipTwo suborbital rocketplane safely landed back in New Mexico Saturday after a “computer communications loss” triggered an abort of the craft’s engine ignition sequence.

The first official launch weather outlook issued Tuesday by U.S. Air Force meteorologists predicts an 80 percent chance of favorable conditions for the predawn liftoff Saturday of SpaceX’s Crew Dragon spacecraft on a test flight to the International Space Station.

A SpaceX Falcon 9 rocket lifted off from Cape Canaveral at 1:50 a.m. EDT (0550 GMT) Sunday with the Telstar 19 VANTAGE communications satellite, a powerhouse spacecraft designed to beam broadband and in-flight WiFi signals across the Americas and the North Atlantic. The rocket’s first stage successfully landed at sea aboard SpaceX’s drone ship.
