    Space is a promising medium for quantum communications, boasting potentially better link performance compared to optical fibers. A future quantum internet, therefore, may rely heavily on satellite networks, which present various open networking challenges, one of which is routing, that today lack definitive solutions, sometimes even in the case of classical networks too. Nonetheless, with ever-bigger satellite constellations, this new plane of networking is slowly becoming a reality. To address the problem of dynamically changing links and handle the unique behavior of quantum repeater protocols, we propose a simple method based on a modified variant of the standard A* graph search algorithm. We then simulate a Starlink-like LEO constellation with simplified models for the main steps of quantum repeater protocols to investigate the feasibility of our method and future quantum satellite networks.
