After analyzing launch vehicle behavior in the Mercury-Redstone 1A (MR-1A) and Mercury-Redstone 2 (MR-2), officials at the Marshall Space Flight Center and the Space Task Group were of the opinion that there were a number of problems that needed to be corrected prior to the advent of manned flight. The problems to be resolved included jet-vane vibration, instrumentation compartment vibration, failure of the thrust-controller system, and several other areas that needed attention. Many of these problems were studied by the personnel of engineering activities and proposed solutions were formulated. It was felt, however, that flight was necessary to verify the corrections and the Mercury-Redstone Booster Development test was scheduled and flown. All test objectives were met; as a result of this test, the launch vehicle was man-rated for the planned suborbital flights. The program insignia shown above is post factum. References:
