NASA will reset EVA after eliminating the imminent threat from space debris

According to NASA, extravehicular activity planned on Tuesday to replace the failed antenna on the International Space Station will not pose a risk to repair work due to the space debris location cited due to delays, Mission Control concludes. After attaching, it was postponed for 48 hours.

NASA officials admitted that two U.S. astronauts were originally on Tuesday, despite a slight increase in risk levels from low-Earth orbit scattered debris from this month’s Russian anti-satellite missile test. I was planning to go out of the space station in the morning and start working.

However, about five hours before going out, NASA warned Mission Control that the U.S. military’s Space Surveillance Network had detected debris that could collide with the space station, after which EVA began. Announced that it was temporarily suspended. The origin of the debris was not revealed in NASA’s announcement.

On Tuesday afternoon, NASA said an assessment of the situation “determined that the orbit of the wreckage would not pose a risk to the planned EVA or space station operations.”

Antenna repairs will be rescheduled on Thursday, with astronauts Tom Marshburn (61) and Kayla Barron (34) six and a half hours from 7:10 EST (1210 GMT). I was planning to start extravehicular activities.

NASA spokesman Gary Jordan said about the size of the debris, the proximity to the space station orbiting about 250 miles (402 km) from Earth, or whether one or more objects were involved. He said no information was available.

“There are no signs that this is relevant,” Jordan added to Reuters by email in a Russian missile test a few weeks ago.

The planned “extravehicular activity,” or EVA, will be the fifth spacewalk after two space flights by doctor and former flight surgeon Marshburn. For NASA.

Their purpose is to remove the failed S-band wireless communication antenna assembly, which is now over 20 years old, and replace it with a new spare housed outside the space station.

According to the plan, Marshburn, with the help of NASA crew Rajachari, is placed at the end of a robotic arm operated from inside the station by German astronaut Matthias Maurer of the European Space Agency, Baron. To cooperate with.

The four arrived at the station with a SpaceX Crew Dragon capsule launched from the Kennedy Space Center in Florida on November 11, and two Russian astronauts and NASA astronauts already on board the Space Research Institute. Joined.

Four days later, Russia launched a missile on one of its non-functional satellites in an unannounced space weapons test, creating a large orbital debris field that caused an emergency on the space station. According to NASA, all seven crew members were able to scramble, evacuate to a docked spacecraft, and quickly escape until the imminent danger disappeared.

Residual debris clouds from the bombed satellites have since dissipated, according to Dana Weigel, deputy manager of NASA’s space station program.

However, NASA said the remaining debris continued to pose a “slightly elevated” background risk across the orbital platform, with a 7% higher risk of a flat tire in a spacewalker’s suit compared to before the Russian missile test. I’m calculating. ..

NASA has not yet fully quantified the risks posed by over 1,700 large debris tracking around the station’s orbit, but the 7% higher risk to spacewalkers was previously seen in the “natural environment.” Weigel said it was “well within” of the fluctuations.
