I’m now very curious if this project is actually the long-gestating Luna Park. That movie first popped up in September of 2015, and while we haven’t heard much about it recently, it’s a project Tom Cruise reportedly was interested in making prior to the last Mission: Impossible film, though that didn’t end up happening. Luna Park is also a project written and directed by Doug Liman, and the movie is said to be about renegade space workers, so it fits with the apparent desire to film in space. Of course, it could be something entirely different, whether or not Luna Park ever happens.
