Live coverage: International Space Station crew lands in Kazakhstan

SpaceX test-fired a Falcon 9 rocket at Cape Canaveral Friday evening, igniting nine Merlin engines for several seconds while hold-down restraints kept the launcher on the ground. The company also confirmed the rocket is scheduled for takeoff Wednesday on a space station resupply mission, three days later than previously planned.

Wrapping up a nine-day mission, four commercial astronauts on Axiom Space’s second flight to the International Space Station departed the orbiting research complex at 11:05 a.m. EDT (1505 UTC) Tuesday. The crew rode back to Earth inside a SpaceX Dragon crew capsule for splashdown in the Gulf of Mexico at 11:04 p.m. EDT (0304 UTC).

NASA announced Thursday it will fund four concept studies for potential robotic missions to Venus, Jupiter’s moon Io and Neptune’s moon Triton ahead of a decision next year to approve up to two of the projects for launch in the mid-to-late 2020s.
