Mercury-Atlas 2 (MA-2) was launched unmanned on February 21, 1961 at 14:10 UTC, from Launch Complex 14 at Cape Canaveral, Florida. Test objectives for this flight were concerned with the ability of the spacecraft to withstand reentry under the temperature-critical abort conditions and with the capability of the Atlas to meet the proper injection conditions. This Atlas "D" modified for the Mercury mission, was unique in the program in that it incorporated a stainless steel reinforcing band installed around the vehicle between stations 502 and 510. A thin sheet of asbestos was installed between the reinforcing band and the tank skin. This modification was installed as a precaution against the type of failure which had occurred on the previous MA-1 flight. MA-2 flew a successful suborbital mission that lasted 17 minutes 56 seconds. Altitude reached was 114 miles (183 km), speed, 13,227 mph (21,287 km/h). All test objectives were fully met. The capsule was recovered 1,432 miles (2305 km) downrange. Peak acceleration was 15.9 g (156 m/s²). Mass 1,154 kg.
Mercury spacecraft # 6 and Atlas # 67-D were used in the mission.
Mercury spacecraft # 6 used in the Mercury-Atlas 2 mission, is currently displayed at the Houston Museum of Natural Science, Houston, TX.[1]
