One significant concern for astronauts above the ISS is a zippered orbital debris around the planet and can cause potential hazards for the space station. While orbital debris have never been a significant problem for ISS and astronauts on board, recently, the impact with orbital debris occurs. The Canadarm2 robot arm attached to the ISS used to manipulate cargo, and other objects outside the space station recently hit by a piece of orbital debris.
It is not clear exactly when the impact occurs. The damage to the robot arm was considered during the routine examination of the arm on May 12. The Canadian Space Agency and NASA worked together to take detailed images of the area and assess the impact on one of the boom parts of the arm. The space agency said that the ongoing analysis showed that the robot arm performance remained unaffected.
Space institutions report that arm damage is limited to small parts of the arm arm and thermal blanket. Canadarm2 is expected to continue to carry out a fully planned operation, including lifting Dekstre to the position to replace the damaged power switch box. Both NASA and the Canadian Space Agency said they would continue to collect data to conclude analysis, and short-term robotic operations continued as planned.
NASA and his partner agent have a long list of guidelines to ensure that the crew above the space station is safe. Both NASA and CSA say the security of astronauts above the ISS is a top priority for all station partners. At present, more than 23,000 softball size objects or larger are traced continuously to warn potential collisions with satellites or ISs.
However, various small objects that include the size of dust and stone particles to cut paint from satellites is too small to monitor. Traveling at a very high speed, even small pieces of rubble raises potential hazards for ISS.
