Live coverage: Veteran three-man crew docks with space station

Eighteen astronauts have been selected — nine men and nine women — to begin training for upcoming Artemis missions to the moon, NASA announced Wednesday. The list includes the as-yet-unnamed next man and first woman who will set foot on the lunar surface later this decade.

Two space station astronauts are gearing up for a planned six-and-a-half-hour spacewalk Friday to replace a presumably shorted out solar array voltage regulator that knocked one of the lab’s eight power channels out of action late last year.

The quartet is set to liftoff from Launch Complex 39A at NASA’s Kennedy Space Center on Thursday, July 31. Their Dragon spacecraft, Endeavour, will fly for a record-setting sixth time.
