There are about 22,000 large objects orbiting the Earth, including working and broken satellites and bits of old rocket from past space expeditions. If you include all the equipment dropped by astronauts while floating in space and the debris from colliding satellites down to around 1 centimeter in size, there are about one million bits of space junk in Earth’s orbit.

British Satellite Tests its Space Junk Harpoon

Last summer, a new type of debris-hunting satellite was released from the International Space Station (ISS). It’s known as the RemoveDebris spacecraft, a technology-demonstrator developed by Surrey Satellite Technology Ltd and the Surrey Space Center. The purpose of this satellite is to test whether satellites equipped with targeting software, a debris net and a harpoon are effective at combating space debris.

Orbital debris (aka. space junk) is one of the greatest problems facing space agencies today. After sixty years of sending rockets, boosters and satellites into space, the situation in the Low Earth Orbit (LEO) has become rather crowded. Given how fast debris in orbit can travel, even the tiniest bits of junk can pose a major threat to the International Space Station and threaten still-active satellites.
