Space Debris Collision Detection using Reachability
EPiC Series in Computing, 2018 Benchmark Proposal: Space debris tracking and collision prediction is a growing world- wide problem as more and more objects are placed into orbit. While traditional methods simulate particles with Gaussian uncertainty to make collision predictions, we instead ana- lyze the problem from a reachability perspective. The problem appears to require methods
