Display Status:

This object is on display in the Barron Hilton Pioneers of Flight Gallery exhibition at the National Air and Space Museum in Washington, DC.

Collection Item Summary:

This is the American Rocket Society's ARS Rocket Motor No. 1. It was meant to launch the Society's Rocket No. 1 but the vehicle was damaged during a static test and the motor wound up powering ARS Rocket No. 2 on 14 May 1933. This was the Society's first flight. The motor is thus called ARS Rocket Motor No. 1 & 2. ARS No. 2 was launched from the beach at Marine Park, Great Kills, Staten Island, New York, and went up 250 feet in two seconds.

The aluminum motor used gasoline and liquid oxygen and was designed by Hugh Franklin Pierce and G. Edward Pendray of the Society's Experimental Committee. It was donated in 1966 to the Smithsonian by the American Institute of Aeronautics and Astronautics.
