Live coverage: Perseverance rover lands on Mars

Today marks the 40th anniversary — July 20, 1976 — of the first U.S. robotic landing on another planet by the Viking 1 spacecraft on Mars.

A day after aborting a rendezvous to resolve a navigation glitch, SpaceX’s Dragon cargo craft made a smooth final approach to the International Space Station on Thursday, floating in range of the research lab’s robot arm for capture at 5:44 a.m. EST (1044 GMT).

A malfunction during a drop test over Nevada last month for SpaceX’s Crew Dragon program has engineers re-examining the crew capsule’s parachutes, and Boeing has also encountered parachute failures during testing for its commercial crew capsule, a senior NASA official confirmed Wednesday.
