Debris risk forces NASA to delay mission to fix ISS antenna

A planned spacewalk to repair a faulty antenna on the International Space Station (ISS) has been postponed indefinitely, the United States space agency NASA says, citing a "debris notification" it received for the orbiting research laboratory. Two US astronauts had been scheduled to venture outside the space station at 7:10am Eastern Time (12:10 GMT) on Tuesday 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. But about five hours before the outing was to have commenced, NASA said on Twitter the spacewalk had been called off for the time being. "NASA received a debris notification for the space station. Due to the lack of opportunity to properly assess the risk it could pose to the astronauts, teams have decided to delay the Nov. 30 spacewalk until more information is available," the space agency tweeted.
