Live coverage: Rosetta’s final hours

NASA’s OSIRIS-REx spacecraft moved within about 131 feet, or 40 meters, of asteroid Bennu this week in the $1 billion mission’s final practice run before a touch-and-go landing on the asteroid in October to collect samples for return to Earth.

Five days after taking off on a heavy-lift Long March 5 rocket, China’s Chang’e 5 sample return spacecraft entered orbit around the moon Saturday, moving into position for a descent to the lunar surface in a bid to gather specimens and bring them back to Earth.

SpaceX launched a Falcon 9 rocket at 8:51 a.m. EST (1351 GMT) Sunday from Cape Canaveral with the first in a new line of upgraded U.S. Air Force GPS navigation satellites. The launch was delayed five days due to technical and weather concerns.
