Space junk has been a growing a problem. Earlier this month, sky watchers in California watched mysterious golden streaks moving through the night sky. US officials later determined that the light show was caused by burning debris from a Chinese rocket re-entering earth’s orbit. US space agency Nasa confirmed that an object that crashed into a home in Florida last month was part of the International Space Station (ISS). The metal object was jettisoned from the orbiting outpost in March 2021, Nasa said. Is the International Station Station becoming risky to humans ?
