Mercury Little Joe 2 (LJ-2) -
LJ-2 was launched from Wallops Island to determine the motions of the
spacecraft escape tower combination during a high-altitude abort, entry
dynamics without a control system, physiological effects of acceleration
on a small primate, operation of the drogue parachute, and
effectiveness of the recovery operation. Telemetry was set up to record
some 80 bits of information on the flight. The abort sequence was
initiated by timers after 59 seconds of elapsed flight time at an
altitude of about 96,000 feet and a speed of Mach 5.5. Escape motor
firing occurred as planned and the spacecraft was whisked away at a
speed of about Mach 6 to an apogee of 53.03 statute miles. All other
sequences operated as planned, and spacecraft recovery was effected in
about 2 hours from lift-off. The primate passenger, 'Sam,' an
American-born rhesus monkey, withstood the trip and the recovery in good
condition. All objectives of the mission were met (http://www.astronautix.com/project/mercury.htm).
