Soyuz MS-14 is slated to be a rare uncrewed Soyuz spacecraft. It is expected to launch atop a Soyuz 2.1a rocket, testing modifications of the launch abort system’s integration to the rocket. Crewed Soyuz spacecraft typically launch on the Soyuz-FG rocket, which is being phased out.
Once in orbit, the spacecraft will spend two days catching up and rendezvousing with the International Space Station to dock with the Poisk module. It is expected to stay aboard the outpost for several weeks before undocking, de-orbiting and landing in Kazakhstan.
