The Little Joe 1B was a suborbital launch escape system test of the Mercury spacecraft, conducted as part of the U.S. Mercury program. The mission also carried a female rhesus monkey (Macaca mulatta) named Miss Sam in the Mercury spacecraft.
SuborbitalThe Pioneer P-1, -3, -30 and -31 series was intended to be a lunar orbiter probe, but the mission failed shortly after launch. The objectives were to place a highly instrumented probe in lunar orbit, to investigate the environment between the Earth and Moon, and to develop technology for controlling and maneuvering spacecraft from Earth.
Lunar OrbitLittle 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.
SuborbitalExplorer 7 was designed to measure solar x-ray and Lyman-alpha flux, trapped energetic particles, and heavy primary cosmic rays. Secondary objectives included collecting data on micrometeoroid penetration, molecular sputtering and studying the Earth-atmosphere heat balance.
