The Microscopic Pieces of Debris Hurtling Through Space
Microscopic Pieces of Debris Hurtling Through SpaceBy Farhana. There are about 70,000 pieces of space junk larger than a softball flying around the Earth, and some of it is burning up as it enters the atmosphere. Luckily, we haven’t had any big incidents yet. But as the population of space junk increases, collisions between orbiting objects have become more common, and nobody’s sure what will happen if we reach the point of critical mass. Do we have any control over it? And what would happen if that critical mass was breached?
