Mercury Redstone BD

NSSDCA ID: MERCRBD
COSPAR ID: 

Description

The Mercury Redstone Booster Development (MR-BD) flight was the last unmanned Mercury Redstone. The purpose of the flight test was to provide a final check of the launch-vehicle system prior to the manned suborbital flights. The objective was to investigate corrections to booster problems resulting during the MR-2 flight. These problems included: (1) structural feedback to the control system producing vane "chatter"; (2) instrument compartment vibration; and, (3) thrust control malfunction.

The launch vehicle achieved a maximum velocity of about 8,200 km/hour and an altitude of 180 km. The capsule travelled nearly 500 km down range for a flight that lasted 8 minutes and 23 seconds. All test objectives of the flight were met. As a result, the launch vehicle was approved for the planned manned suborbital flights.
