A spacewalk planned for Tuesday to repair a faulty antenna on the International Space Station was postponed indefinitely, NASA said, citing a “debris notification” it received for the orbiting research laboratory.
Two U.S. astronauts had been scheduled to venture outside the space station at 7:10 a.m. ET to begin their work, facing what NASA officials had called a slightly elevated risk posed by debris from a Russian anti-satellite missile test this month.
