ST&RS is a world-wide organization that handles all space-affairs. It was formed after the Message had arrived. One of ST&RS' duties is to train astronauts so that they will be ready on Mars the 7th of August 2035. In order to fullfill that promise, ST&RS founded the Space Academy, with the girl from the Message, Fifie Collins as principal.
ST&RS stands for Space agency for Transcendent and Revolutionary technology of Spaceman.
