Little Joe 1A (LJ-1A) was an uncrewed rocket launched as part of NASA's Mercury program on November 4, 1959. This flight, a repeat of the Little Joe 1 (LJ-1) launch, was to test a launch abort under high aerodynamic load conditions. After lift-off, the pressure sensing system was to indicate when the correct abort dynamic pressure was reached. This should have happened about thirty seconds after launch. Because of this, a repeat of the test was planned. Other events from launch through recovery occurred without incident. Payload 1,007 kg.
