The next American polar-orbiting weather satellite that will feed long-range forecasts and track environmental trends has slipped into space-like testing ahead of launch.

SpaceX test-fired a Falcon 9 rocket at Cape Canaveral on Saturday evening, clearing the way for a delayed liftoff with the Israeli-owned Amos 17 commercial communications satellite as soon as Tuesday, assuming SpaceX can work its way into a busy schedule before a previously-planned Atlas 5 launch this week on the U.S. Air Force’s Eastern Range.

India’s Geosynchronous Satellite Launch Vehicle Mk.2 lifted off at 1040 GMT (5:40 a.m. EST; 4:10 p.m. Indian Standard Time) with the GSAT 7A communications satellite for the Indian Air Force. The rocket placed the spacecraft into a supersynchronous transfer orbit around 19 minutes after liftoff from Sriharikota on India’s east coast.
