Live coverage: SpaceX launches another batch of Starlink satellites

Two U.S.-German satellites launched more than 15 years ago to measure Earth’s changing gravity field will stop collecting data in November, a few months before a pair of replacement craft will launch to resume gravity measurements, NASA officials said.

In a major shift, NASA is considering using two commercial launchers to send an unpiloted Orion crew capsule and its European-built service module on a test flight around the moon next year, maintaining the lunar test flight’s schedule despite fresh delays in the development of the multibillion-dollar Space Launch System that jeopardize the heavy-lifter’s 2020 inaugural flight, the agency’s administrator said in a congressional hearing Wednesday.

SpaceX launched a Falcon 9 rocket carrying 25 Starlink satellites from California early Saturday, after days of delay. Liftoff from Space Launch Complex 4 East at Vandenberg Space Force Base occurred at 1:04:19 a.m. PST (4:04:19 a.m. EST / 0904:19 UTC).
