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).

SpaceX’s next Falcon 9 rocket launch, using a previously-flown first stage booster, took a step closer to liftoff Thursday with a countdown rehearsal culminating in ignition of the launcher’s nine Merlin main engines in a hold-down firing at pad 39A at NASA’s Kennedy Space Center in Florida.

A commercial Northrop Grumman Cygnus supply ship berthed at the International Space Station fired its main engine for 50 seconds Tuesday in a test of the spacecraft’s ability to reboost, and possibly eventually deorbit, the massive research outpost.
