EXPERIMENT MODULE
Shortly before the most recent X-37B launch, the US military revealed the spy plane had a new service module that allowed for large numbers of experiments to be carried to orbit. The mission deployed a small satellite known as Falconsat-8, containing five experimental payloads, some developed by the US Air Force and some by NASA. While NASA has stated that it was flying an experiment on a previous X-37B flight, this was the first time the military had disclosed any specifics about such cargo.
