The term 'satellite launcher' can be broken down into two parts: Agena (5 letters) and NASA (4 letters). Agena was a series of upper-stage rockets developed by the Lockheed Corporation in the 1950s and 1960s. It was used as an upper stage for various launch vehicles, including the Atlas and Thor missiles. NASA, or the National Aeronautics and Space Administration, is an independent agency of the United States government responsible for the civilian space program, as well as aeronautics and aerospace research. Agena and NASA worked together to develop and launch satellites, making them an integral part of the satellite launcher team.
