A Vega rocket launched from French Guiana at 0149:24 GMT Tuesday (8:49:24 p.m. EST Monday) with Europe’s fifth Sentinel environmental satellite. The Sentinel 2B observatory will take the pulse of Earth’s vegetation, monitoring crops, forests, urban sprawl, and pollution from polar orbit.

For the second time this year, SpaceX has launched a commercial communications satellite for Tokyo-based SKY Perfect JSAT Corp. A Falcon 9 rocket blasted off at 1:26 a.m. EDT (0526 GMT) from Cape Canaveral with the JCSAT 16 satellite to relay data and video across Japan and the Asia-Pacific. The Falcon 9’s first stage booster nailed a landing on a barge in the Atlantic Ocean a few minutes later.

NASA and U.S. military officials are reviewing a malfunction that triggered a premature engine shutdown during a flight of a SpaceX Falcon 9 rocket earlier this month, a cautionary step before upcoming launches with a GPS navigation satellite and astronauts on SpaceX’s Crew Dragon spacecraft.
