Space junk is a major problem. Consisting of detritus like old rocket stages and broken up pieces of satellites, these pieces of debris orbit the Earth at terrifying speeds, posing a risk to both satellites and future space missions. According to some estimates, there are around 34,000 pieces of debris larger than 10 centimeters currently floating in space. While there have been numerous ideas put forward for cleaning up this space trash, a new concept may be the most ambitious (and, frankly, kind of bonkers-sounding) yet.
