A 67-newton engine, designated XR2P1, using nitrous oxide and ethane as propellants, was initially built to test the design of proposed larger engines. With a cumulative burn time of 103 minutes, this engine had completed in excess of 1,189 runs. It continued to serve as a workhorse engine for a wide variety of experiments, crew training activities, and educational demonstrations. The XR2P1 has run on oxygen and nitrous oxide oxidizers, with propane, ethane, kerosene, turpentine, and a variety of alcohols.
