Communications Satellite, Westford, Dipole Dispenser

Communications Satellite, Westford, Dipole Dispenser

     

Launched by the U.S. Army in 1958, the Westford satellite used a unique concept to test the new undertaking of satellite communications from space. Once in space, the dispenser (this artifact) via a spring mechanism pushed the canister, packed with thousands of tiny needles (dipoles), into orbit. The needles in the canister slowly separated and formed a ring around the Earth. Antennas on the ground bounced radio signals off the ring of needles to communicate.

The museum's satellite is a prototype.

Transferred from the National Museum of American History to the Museum in 2004.
