Live coverage: Japanese cargo craft arrives at space station

An Indian radar observation satellite designed to collect information on natural disasters, pollution and monitor the military activity of India’s neighbors lifted off at 4:55 a.m. EST (0955 GMT) Wednesday on top of a Polar Satellite Launch Vehicle, the second PSLV mission in two weeks.

Mission managers are weighing a motley mix of weather models, safety criteria and astronaut workload considerations as they decide when SpaceX’s Crew Dragon spacecraft might have the best chance to launch from the Kennedy Space Center.

Officials from NASA and SpaceX briefed the media on Monday’s scheduled launch of a commercial Dragon spacecraft on an automated resupply mission to the International Space Station. It will be the 12th SpaceX cargo flight to the research outpost.
