Seattle-based Spaceflight Inc. says it’ll use a notebook-sized deorbiting system developed by another Seattle-area company to deal with the disposal of its Sherpa-FX orbital transfer vehicle.
The NanoSat Terminator Tape Deorbit System, built by Bothell, Wash.-based Tethers Unlimited, is designed to take advantage of orbital drag on a 230-foot-long strip of conductive tape to hasten the fiery descent of a spacecraft through Earth’s atmosphere. The system has been tested successfully on nanosatellites over the past year, and another experiment is planned for later this year.
Tethers Unlimited’s system provides an affordable path to reducing space debris, which is becoming a problem of greater concern as more small satellites go into orbit. Statistical models suggest that there are nearly a million bits of debris bigger than half an inch (1 centimeter) whizzing in Earth orbit.
