To solve this problem, engineers at the Ecole Polytechnique Federale de Lausanne (EPFL) and Swiss Space Systems (S3) have created a satellite that can orbit the planet collecting space debris. What’s more, the group says they do this extra-planetary clean-up on the cheap.
Called the CleanSpace One, the satellite would start its journey to orbit aboard a Sub-Orbital Reusable shuttle (SOAR) attached to the belly of an A300 jet. Once the jet reaches an altitude of 10km (33,000ft) the SOAR would decouple from the plane and fly to an altitude of 80km (263,000ft) where it would use a rocket to boost itself to its final altitude of 700km (435 miles) above Earth.
To eliminate its payload, the satellite would then orient itself for a kamikaze reentry into the Earth’s atmosphere during which everything would be burnt to a crisp.
According to EPFL engineers, their CleanSpace One plan could reduce satellite launch costs by a factor of four, making space debris collection economical. According to Pascal Haussi, CEO of Swiss Space Systems, “You can’t democratize space access without having a responsible attitude. If we don’t deal with the problem of orbiting space debris and its accumulation, future generations’ access to space will be compromised.”
