CAPE CANAVERAL, Fla.—Spacewalking astronauts replaced a broken antenna outside the International Space Station on Thursday after getting NASA’s all-clear for orbiting debris.
U.S. astronauts Tom Marshburn and Kayla Barron were supposed to complete the job Tuesday, but NASA delayed the spacewalk because of potentially threatening space junk. NASA later determined the astronauts were safe to go out, despite a slightly increased risk of a punctured suit from satellite wreckage.
