NASA astronauts Keira Barron and Thomas Mashburn were already preparing to put on their spacesuits and leave the cabin of the international space station at about 7:10 a.m. EST this morning, In order to replace the antenna outside the space station. This will be Mashburn’s fifth spacewalk and Barron’s first

but before they could leave through the airlock, NASA personnel in the mission control center informed them to stop the spacewalk. “This is real life. Sometimes things are like this. I’m really glad you guys are paying attention to our safety,” Mark van der Hei, one of the astronauts on the international space station, told the flight controller of the mission control center, CBS News

in a short blog post, NASA said that it did not have enough time to “correctly assess” the risk posed by debris to astronauts, so the agency chose to postpone the spacewalk until further notice

this is the second time in the past two weeks that space debris has disrupted the plan of the international space station. On November 15, astronauts on the international space station were awakened in advance by mission controllers and told to take refuge in Russia after anti satellite or anti satellite tests. Russia used some kind of anti satellite missile to blow up one of its satellites, producing at least 1700 traceable fragments and thousands of untraceable small fragments. Because the orbit of the satellite is relatively close to the international space station, the debris cloud will periodically pass near the international space station

NASA did not say whether the debris delaying the spacewalk came from the same anti satellite test. However, NASA hinted that the delay would not have a significant impact on the space station. “The schedule and operation of the space station can easily adapt to the delay of spacewalk,” NASA wrote in its blog post
