The 18th Space Control Squadron (18 SPCS) predicts when and where man-made objects will reenter the Earth’s atmosphere. It does so on behalf of Air Force Space Command (AFSPC), in support of U.S. Strategic Command’s Joint Force Space Component Command (JFSCC), which is charged with executing USSTRATCOM’s presidentially assigned Space Operations mission area. This fact sheet presents how 18 SPCS processes reentries, the systems used to do so, current challenges, and the products, notifications and reports issued throughout the process.
