Live coverage: International Space Station crew lands in Kazakhstan

The world’s most powerful operational rocket flashed to life at 2:30 a.m. EDT (0630 GMT) Tuesday and climbed into a moonlit summer sky from pad 39A at NASA’s Kennedy Space Center in Florida, the same site where the Apollo 11 astronauts left Earth for their historic moon landing nearly 50 years ago.

NASA Administrator Jim Bridenstine says he is “fairly confident” that astronauts can fly to the International Space Station aboard SpaceX’s Crew Dragon spaceship at the end of May or early June, pending final parachute tests, data reviews and a training schedule that can escape major impacts from the coronavirus pandemic.

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.
