Mercury-Atlas 4 was an unmanned spaceflight of the Mercury program. It was launched on September 13, 1961 at 14:09 UTC from Launch Complex 14 at Cape Canaveral, Florida. A Crewman Simulator instrument package was aboard. The craft orbited the Earth once.
This flight was an orbital test of the Mercury Tracking Network and the first successful orbital flight test of the Mercury program. (All previous successful launches were suborbital.) 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. It demonstrated the ability of the Atlas LV-3B rocket to lift the Mercury capsule into orbit, of the capsule and its systems to operate completely autonomously, and succeeded in obtaining pictures of the Earth. It completed one orbit prior to returning to Earth. The capsule was recovered 176 miles east of Bermuda....
