Thanks to Phys.org for running a feature all about the recent preprint article by Olivier Lamarre (STARS) and Shantanu Malhotra (NASA JPL)! The article describes how to define recovery policies to ensure that a solar-powered rover remains safe (i.e., limits the risk of complete battery depletion) while travelling through permanently shadowed regions (at, e.g., the lunar south pole). The full article is under review; read the preprint on arXiv here: https://arxiv.org/abs/2307.16786
