A page from the new version of the Space Rider user guide that collects all the updates since the project passed its critical design review last year, the final step before moving to production.
Space Rider is an uncrewed laboratory about the size of two minivans that will be able to stay in orbit for up to two months. The spacecraft comes in two parts, an orbital module that supplies everything it needs to fly around our planet and a reentry module that brings Space Rider and its experiments back to Earth.
