The International Spaceflight Museum is a virtual museum presently located in Second Life. It hosts exhibits and events about real-world spacecraft, rockets, and space travel. The museum is located on the island sims Spaceport Alpha and Spaceport Bravo.
The in-world organization that manages and develops the museum is the Spaceflight Museum Planning Group, a group of Second Life residents from around the world who share an interest in spaceflight. These same volunteers have created a Real Life organization to support the museum, the ISM Corporation, a Kansas non-profit corporation.
Space CoLab Island is located within close proximity of the museum.
