The mission of the X-37B Space Plane that launched from Cape Canaveral last month was shrouded in secrecy. And while the Pentagon insists that the project seeks "no offensive capabilities" as far as space-based weapons are concerned, Pentagon leaders have said that the spacecraft's ultimate mission would be to assist terrestrial war fighters with any number of missions. Some with inside knowledge of the program have suggested that the vehicle could be testing sensors for a new generation of spy satellites, which the Pentagon has also denied.
