Live coverage: Dragon cargo craft arrives at space station

A month after an X-37B mini-space shuttle glided to a landing on Kennedy Space Center’s runway in Florida, the U.S. Air Force announced Tuesday that the spaceplane’s next mission will launch in August aboard a SpaceX Falcon 9 rocket for the first time.

A commercial cargo carrier owned and operated by SpaceX pulled into port at the International Space Station on Monday, three days after launching from Cape Canaveral with a NASA Earth science instrument, a spare hand for the lab’s Canadian robotic arm, and an AI-powered helper bot for the research lab’s six-person crew.

NASA safety advisors on Thursday lauded hardware milestones on Boeing and SpaceX commercial crew capsules, but said multiple technical issues, including problems with parachutes, must be resolved before the human-rated ships are ready to carry astronauts, adding that both companies continue to pursue schedules that appear to be unachievable.
