Flying on its 40th mission, a Japanese H-2A rocket lifted off at 0408 GMT (12:08 a.m. EDT) Monday from the Tanegashima Space Center carrying Japan’s GOSAT 2 satellite to measure greenhouse gases in Earth’s atmosphere and the KhalifaSat Earth observation satellite for the United Arab Emirates.

NASA announced Friday a mix of spaceflight veterans and rookie astronauts who will launch on the first flights of new Boeing and SpaceX commercial spaceships starting as soon as next spring, several months later than previously scheduled.

The rescheduled mission comes following the April 9 scrub due to poor weather and a period on the Eastern Range marked by a noted lack of orbital launches. Liftoff from pad 41 at Cape Canaveral Space Force Station is targeting Monday, April 28, at 7 p.m. EDT (2300 UTC).
