The National Aeronautics and Space Administration is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA have many launch facilities but most are inactive. The most commonly used pad will be LC-39B at Kennedy Space Center in Florida.
Little Joe 1A (LJ-1A) was an unmanned 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. Due to a delayed in the escape motor startup, the abort maneuver was not accomplished at the desired dynamic pressure, requiring a repeat of the test.
