513:(which was 34 miles from the landing point) picked up the capsule, which was found to be in good condition with little damage from either liftoff, orbit, or reentry. Postflight examination found that the oxygen rate handle had been dislodged by liftoff-induced vibration and cracked open a valve. This had allowed oxygen to escape into space, but not at sufficient rates to trigger a telemetry warning measurement, although it did trigger the oxygen warning light in the capsule. The handle was redesigned afterwards to be more difficult to move. The problem reorienting the capsule after booster separation was found to be the result of an open circuit in the pitch gyro.

forward proved more difficult than expected, taking 50 seconds instead of the normal 20 seconds. At a few points during the mission, the capsule's attitude became slightly unstable due to the failure of two thrusters, which caused momentary telemetry dropouts. The capsule completed one orbit prior to returning to Earth. Reentry took place one hour and 28 minutes after launch, and splashdown occurred in the
Atlantic Ocean 176 miles (283 kilometers) east of

The mission involved testing the Mercury spacecraft, specifically Mercury #8A, which completed one orbit around Earth. This successful flight provided important data and insights for NASA's Project Mercury, supporting the planning and development of upcoming crewed missions in the program.

The payload consisted of a pilot simulator (to test the environmental controls), two voice tapes (to check the tracking network), a life support system, three cameras, and instrumentation to monitor levels of noise, vibration and radiation.

The MA-4 mission had successfully achieved all its flight objectives. It had demonstrated the ability of the Atlas LV-3B rocket to lift the
Mercury capsule into orbit and of the capsule and its systems to operate completely autonomously, and it had succeeded in obtaining pictures of the Earth.

The biggest problem encountered on
Mercury-Atlas 4 was an uncomfortably high level of liftoff vibration from T+5 to T+20 seconds, so a few more small modifications were made to the Atlas's autopilot. However,

Nonetheless, to be on the safe side and test out a few more design changes, NASA still planned for one more uncrewed test before committing the
Mercury-Atlas combo to a crewed flight.
