Live coverage: International Space Station crew lands in Kazakhstan

Astronauts Peggy Whitson and Jack Fischer put on spacesuits Friday and headed outside the International Space Station for several repair and maintenance tasks, but the duo only completed part of their originally planned work after a leaky cooling umbilical delayed the start of their spacewalk.

Closing out 52 days at the International Space Station, an automated Northrop Grumman Cygnus cargo craft left the research outpost Sunday to climb into a higher orbit for deployment of six CubeSats and further engineering experiments, before de-orbiting over Pacific Ocean later this month.

A commercial lunar lander built by Astrobotic will launch from the Kennedy Space Center on a SpaceX Falcon Heavy rocket in late 2023 to deliver a water-hunting NASA rover to the moon’s south pole, officials announced Tuesday.
