The Solution to Dangerous Space Junk is, Evidently, a Giant Harpoon

In space, no one can hear you scream… which is what you would probably be doing if your shuttle or one of your precious satellites was suddenly obliterated by one of the thousands upon thousands of pieces of space junk that are hurtling around the Earth’s orbit at breakneck speeds of up to 30,000 miles per hour. Because these tiny pieces of debris are traveling at such immense speeds, the process turns even the smallest bit of detritus into an incredibly dangerous projectile. Thankfully, Elon Musk and SpaceX are stepping up the plate to help make outer space a cleaner place. In early April, a SpaceX Falcon 9 rocket launched a reused Dragon capsule to the International Space Station, which contained an experimental new space debris removal system known as “RemoveDebris.” Its mission: to Aquaman the ever-loving hell out of space junk.

One interesting wrinkle in the experiment, according to, is that the University of Surrey team has to bring their own debris with them in order to test this system due to current laws preventing outside entities from handling objects in space that belong to another party, even if they are no longer operational.

“You can’t just go up there and capture someone else’s debris,” said Jason Forshaw, the RemoveDebris project manager at the University of Surrey’s Surrey Space Centre, to “That’s why for this mission we are actually ejecting our own little cubesats.”

The team will attempt to demonstrate active removal of debris by launching two cubesats. They will capture one satellite by using the aforementioned net, and they will employ both a Lidar system and an optical camera to launch a harpoon into the other cubesat in order to test vision-based technologies in space. Once its mission is complete, the RemoveDebris system’s main platform will deploy its dragsail and slowly reenter the Earth’s atmosphere within a period of two years.

While there’s still a long way to go until these speeding trash bullets are cleaned up once and for all, we can breathe a bit easier known that we’re not headed for a horrifying, Planetes-style future.
