Q&A with NASA Administrator Jim Bridenstine (members only)

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.

The launch of a SpaceX Falcon 9 rocket Aug. 24 from California delivered Taiwan’s Formosat 5 Earth-imaging satellite to orbit, and the Falcon’s first stage booster returned to landing on a drone ship downrange in the Pacific Ocean.

Two U.S.-built communications satellites rode the 100th European-made Ariane 5 rocket into orbit Tuesday from the jungle of French Guiana. Liftoff occurred at 2238 GMT (6:38 p.m. EDT) after a 45-minute delay caused by a range technical problem.
