A company called Tethers Unlimited has deployed its de-orbiting tether in a successful test on the Prox-1 satellite. The satellite is one of four that are carrying the device, called the Terminator Tape. Rather than stay in space for years or decades and add to the growing problem of space debris, Prox-1 is using its Terminator Tape to slowly lower its orbit.
