Live coverage: Space station crew safely returns to Earth

NASA has a builder to construct a five-ton spacecraft to catch up with the aging Landsat 7 Earth observation satellite and refuel it in 2020, employing robotic tools mastered in years of rehearsals on the International Space Station.

Much of the rover was complete and it was going through a series of testing when the project was scrapped. NASA said Astrobotic’s Griffin lander, which was supposed to carry VIPER to the Moon’s South Pole, will still proceed with its mission.

Watch as a Falcon 9 rocket with the first Crew Dragon capsule atop, briefly fired its engines for a crucial pre-launch test on Jan. 24, 2019.
