Live coverage: Two Americans, one Russian back on Earth from space station

Europe’s Sentinel 2A land imaging satellite designed to glimpse cities, farms and forests from orbit launched aboard a Vega rocket. The 2,500-pound satellite lifted off at 0151:58 GMT Tuesday (9:51:58 p.m. EDT Monday).

In the week since it departed the International Space Station to wrap up a successful cargo delivery mission, Orbital ATK’s Cygnus supply ship hosted a combustion research experiment, deployed four small satellites for a San Francisco-based startup, then descended into Earth’s atmosphere Sunday for a destructive re-entry.

The final major test of the high-power launch abort engines on SpaceX’s Crew Dragon spacecraft before astronauts climb aboard for a flight to the International Space Station is scheduled for Jan. 18 from NASA’s Kennedy Space Center in Florida, NASA announced Monday.
