Super-fast space junk punches hole through space station

A small hole was discovered in the ISS's Canadarm2, a robotic arm used for maneuvering objects. Despite the damage, the arm is functioning normally. The incident highlights the growing problem of space debris, which poses a significant threat to the ISS and other satellites. With millions of tiny fragments orbiting Earth, the risk of collision is increasing, necessitating emergency maneuvers to avoid damage.
