Live coverage: International Space Station crew lands in Kazakhstan

Three crewmen from Russia, the United States and Great Britain blasted off toward the International Space Station on Tuesday, rocketing into space from the Baikonur Cosmodrome in pursuit of the orbiting research lab.

Two software errors detected after launch of a Boeing Starliner crew ship during an unpiloted test flight last December, one of which prevented a planned docking with the International Space Station, could have led to catastrophic failures had they not been caught and corrected in time, NASA said Friday.

On the eve of its blazing entry into the Martian atmosphere, NASA’s InSight spacecraft briefly pulsed its control jets Sunday to target a safe, flat landing zone near the planet’s equator — the last in a series of trajectory correction maneuvers since the mission’s launch in May.
