Space Debris Mitigation

The proliferation of space debris in Earth’s lower orbit poses a formidable threat to our vital space assets, including satellites and space stations. A pioneering research endeavor at West Virginia University, bolstered by NASA’s support, is exploring the potential of harnessing AI-powered space lasers to mitigate the risks associated with these orbiting hazards.

The ambitious initiative seeks to develop a coordinated network of space lasers capable of redirecting debris, regardless of its size, away from potential collision courses with critical space infrastructure. The underlying principle is to employ artificial intelligence to empower these lasers to swiftly respond to debris of varying dimensions.

Hang Woon Lee, the director of the Space Systems Operations Research Laboratory at WVU, underscores the pressing issue of human-made debris accumulating around Earth. As the debris population in orbit escalates, so does the peril of collisions with both manned and unmanned space assets. Lee advocates for an array of multiple lasers positioned on space platforms as the most viable means of averting these collisions. These AI-powered lasers can collaborate and adapt to efficiently address debris, regardless of its size.

Lee’s groundbreaking research has earned recognition from NASA, which has awarded him the prestigious Early Career Faculty award for potentially game-changing research. NASA’s financial support of $200,000 per year for up to three years underscores the significance of this endeavor.

While the research is in its nascent stages, the team is diligently validating the proposed algorithms that will govern the laser system’s operations. The ultimate vision is a network of reconfigurable space-based lasers, orchestrated by a suite of cutting-edge algorithms. These algorithms represent the linchpin technology that will enable the network to function optimally, delivering real-time collision avoidance for high-value space assets.

The escalation of space debris, coupled with the surge in commercial activities in Earth’s low orbit, underscores the urgency of addressing this issue. Lee highlights the potential catastrophic consequences of collisions in space, including the dreaded “Kessler Syndrome,” which could render space unsustainable and perilous.

Compared to other debris removal technologies such as hooks, harpoons, nets, and sweepers, Lee’s approach exhibits versatility in handling debris of various sizes. The suite of algorithms under development will empower lasers mounted on large satellites or dedicated platforms to make autonomous decisions regarding target selection and priority. This ensures that the trajectories of debris remain collision-free.

It’s important to note that the laser beams don’t obliterate debris; instead, they alter its orbit through a process known as laser ablation. This involves vaporizing a portion of the debris, generating a high-velocity plasma plume that nudges the debris onto a new course. This ability to modify the debris’s orbit is a critical advantage, as a network of lasers can collaboratively and efficiently control trajectories, offering multiple engagement opportunities with debris.

Lee’s collaboration with Scott Zemerick, chief systems engineer of TMC Technologies, to validate models and algorithms within a digital twin environment ensures that the resulting products are flight software-ready, marking a significant step toward a future where AI-enhanced lasers safeguard our valuable space assets.
