Space junk could have a transcendent, purposeful afterlife
The idea of a skyhook has been under study for half a century now; it would take the form of a long and strong tether extending from a base station on Earth’s surface into space. The other end of the tether, a counterweight like Envisat, would remain in orbit around Earth. As the tether rotates, the counterweight generates centrifugal force, creating tension in the tether. Spacecrafts and payloads can then be attached to the tether and released into space when they reach the desired velocity, essentially ‘hooking’ them into orbit. The counterweight’s substantial mass and its fixed position in space would act as the pivot point for the entire system, allowing the tether to maintain tension and transfer momentum. Depending on the tether’s length, materials and the specific rotational characteristics of the skyhook, the momentum it imparts to payloads could potentially extend their reach beyond Earth’s orbit to reach other celestial bodies. Further into the future, skyhooks could span across three celestial bodies – Earth, the Moon and Mars – forming a seamless interconnected network.
