Vehicle 57

First flight of Vehicle 57 Mimas, powered by an Aerotech E30-4T composite motor. The rocket carried a Transolve Ultra-Beep sonic beacon.

After an initial misfire upon ignition, the ascent portion of the flight was perfect. But upon parachute ejection, the payload section separated due to an attachment point failure. The main section of the rocket was recovered intact, the payload section and payload were found with some damage, and the nose cone was lost. Vehicle 57 was later fully repaired and still exists to this day.

Vehicle 57 measured 1070 mm in length and 56 mm to 42 mm in diameter, at a weight (without motor) of 131 grams. It was built in April and May of 1986, from Centuri, Estes, and Flight Systems parts.
