Once in space, the biggest threat to astronauts and spacecrafts is space debris. Space debris, also known as space junk or space waste, are potentially dangerous and useless objects in Earth’s orbit. These objects are either man-made (such as spent stages of rockets, broken off pieces of spaceships or equipment, old unusable satellites, and even small flecks of paint) or natural (such as space rocks, ice, and dust). The problem with space debris is how hazardous they can be if they impact a spacecraft or even a spacewalking astronaut.
