LASAR is developing methods to tackle the problem of space debris. Specifically by using lasers to deorbit debris or to restart non-communicating satellites. Millions of space debris fragments generated by satellite collisions pose a significant threat. These high-speed pieces can collide with operational satellites or manned spacecraft, causing severe damage and generating more debris, risking a domino effect (called Kessler syndrome) that could cripple future space missions.
Some of this space debris is caused by non-communicating satellites on Earth orbit. Over 7% of launched nanosatellites have never communicated with Earth. That is around 170 units. The cost of these lost satellites amounts to over $50,000,000 if we consider construction and launching.
LASAR (Laser-Assisted Satellite Recovery) represents a revolutionary approach to satellite maintenance. This system uses ground-based lasers to restart and repair non-communicating satellites with software issues. The process works by focusing a laser beam on the satellite's solar panels, causing a temporary electrical overload on the control unit, triggering a reboot. During this reboot, a software update can be sent to fix the problems. Additionally, Laser-Assisted Satellite Reentry addresses deorbiting space debris, including small satellites and fragments, by using a laser beam to exert pressure, slowing it down so it eventually burns up in the Earth's atmosphere. This dual functionality makes the method more efficient, cost-effective, and environmentally friendly.
