Live coverage: SpaceX launches another batch of Starlink satellites

A United Launch Atlas 5 rocket is set to dispatch NASA’s InSight lander toward Mars, kicking off an interplanetary journey from Vandenberg Air Force Base in California.

The countdown for a planned launch of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida automatically aborted in the last second before liftoff Sunday after an on-board computer detected unexpected data during an engine power check.

NASA officials have determined that the robotic InSight lander is ready for its mission to Mars after concluding that the probe should not suffer the same flaw that led to a crack in a heat shield undergoing tests for the space agency’s Mars 2020 rover, InSight’s chief scientist said Monday.
