Live coverage: China launches three-man crew to Tiangong space station

Japan’s sixth HTV supply ship departed the International Space Station on Friday and headed for a destructive re-entry over the South Pacific with trash and disused batteries from the research lab, but engineers will first use the spacecraft for a pioneering experiment to investigate a new way to remove space junk from orbit.

The launch of a NASA research satellite built to probe conditions along the boundary between Earth’s atmosphere and space has been tentatively rescheduled for no earlier than Wednesday, pending the conclusion of a review of unexpected data signatures discovered on the first stage of the mission’s air-launched Pegasus XL rocket.

SpaceX has ordered additional inspections on a Falcon 9 rocket at Vandenberg Air Force Base in California,  a decision that is expected to keep the launcher grounded for several days until after the Thanksgiving holiday, officials said Saturday.
