CAPE CANAVERAL, Fla. — A harpoon flung from a satellite has successfully captured a piece of pretend space junk, like a whale.

The British-led experiment is part of an effort to clean up debris in orbit, hundreds of miles above Earth.

The University of Surrey’s Guglielmo Aglietti said Friday that the steel-tipped harpoon scored a bull’s-eye last Friday.

The harpoon – no bigger than a writing pen – pierced an aluminum panel the size of a table tennis racket attached to the end of a satellite boom. The distance was just 5 feet, but researchers were delighted.

A video shows the harpoon slamming into the target and knocking it off its perch, and then the harpoon cable becoming entangled around the boom.

Aglietti said a much bigger harpoon will be needed in order to snare a real dead satellite – “Moby Dick style.”

Thousands of old satellite and rocket parts and other junk circle Earth, a potential threat to working spacecraft, including the International Space Station.

The same team used a net to capture a piece of space junk in a test last September.

And in December, they tracked a tiny satellite ejected from the mother ship, using lasers.

“We are very happy because so far, we have done three experiments and all three have been working,” Aglietti said by phone from England.

All that remains is for the 250-mile-high satellite to re-enter the atmosphere and burn up.

The experiment was launched to the space station last April and released from the station last June.
