Solar spectrum research. Launched at 0830 local time. Reached 158 km.
Little Joe 1-A (LJ-1A) was launched in a test for a planned abort under high aerodynamic load conditions. This flight was a repeat of the Little Joe (LJ-1) that had been planned for August 21, 1959 (escape rocket fired 31 min before the intended launch of the Little Joe launch vehicle). After lift-off, the pressure sensing system was to supply a signal when the intended abort dynamic pressure was reached (about 30 sec after launch). An electrical impulse was then sent to the explosive bolts to separate the spacecraft from the launch vehicle. Up to this point, the operation went as planned, but the impulse was also designed to start the igniter in the escape motor. The igniter activated, but pressure failed to build up in the motor until a number of seconds had elapsed. Thus the abort maneuver, the prime mission of the flight, was accomplished at a dynamic pressure that was too low. For this reason a repeat of the test was planned. All other events from the launch through recovery occurred without incident. The flight attained an altitude of 9 statute miles, a range of 11.5 statute miles, and a speed of 2,021.6 miles per hour.

Fired from AMR at 1938 hours EST to a pre-selected range of 1,299.4 nm. The nose cone impacted 0.56 nm short and 0.09 nm right of the impact point. The test successfully accomplished all intended missions. This was the first highly successful, Chrysler-assembled Jupiter fired in the test program sad was the first fired without static firing.

Enos, the 6-year-old chimpanzee who made a two-orbit flight around the earth aboard the Mercury-Atlas 5 (MA-5) spacecraft (November 29, 1961, entry) died at Holloman Air Force Base, New Mexico. The chimpanzee had been under night and day observation and treatment for 2 months before his death. He was afflicted with shigella dysentary, a type resistant to antibiotics, and this caused his death. Officials at the Air Medical Research Laboratory stated that his illness and death were in no way related to his orbital flight the year before. References: 483 .
This was a DOD sponsored live test of the Nike Hercules air defense missile system. The low-kiloton range W-31 warhead detonated at 21 km altitude 3 km SSW of Johnston Atoll. This was the last U.S. atmospheric test. On Johnston Island an intense white flash was accompanied by a strong heat pulse. A yellow-orange disc formed, slowly changing to a purple toroid which faded from view after several minutes.
Mars probe intended to make a soft landing on Mars. Although the escape stage and payload reached orbit, the strong third stage vibrations shook a fuse loose from its mount in the main nozzle of the escape stage Block L's engine. The engine could not be ignited and remained in Earth orbit. It decayed about two months after insertion. References: 1 , 2 , 5 , 6 , 64 , 65 , 118 , 296 .

NASA announced an Apollo mission schedule calling for six flights in 1968 and five in 1969. NASA Associate Administrator for Manned Space Flight George E. Mueller said the schedule and alternative plans provided a schedule under which a limited number of Apollo command and service modules and lunar landing modules, configured for lunar landing might be launched on test flights toward the moon by the end of the decade. Apollo/uprated Saturn I flights were identified with a 200 series number; Saturn V flights were identified with a 500 series number. Additional Details: Apollo mission schedule for six flights in 1968 and five in 1969. References: 16 .
Venera 13 and 14 were identical spacecraft built to take advantage of the 1981 Venus launch opportunity and launched 5 days apart. After launch and a four month cruise to Venus, the descent vehicle separated and plunged into the Venus atmosphere on 5 March 1982. As it flew by Venus the bus acted as a data relay for the brief life of the descent vehicle, and then continued on into a heliocentric orbit. The parachute of the descent vehicle opened after the lander reached subsonic speed. At an altitude of about 50 km the parachute was released and simple airbraking was used the rest of the way to the surface. Venera 14 landed about 950 km southwest of Venera 13 near the eastern flank of Phoebe Regio at 13 deg 15 min S by 310 E on a basaltic plain. After landing an imaging panorama was started It has been reported that the surface analysis arm accidentally landed on one of the ejected camera covers and therefore didn't send back any data on the Venusian soil. This is visible in photographs sent back. On the other hand, the official account very specifically states that the mechanical drilling arm obtained a sample, which was deposited in a hermetically sealed chamber, maintained at 30 degrees C and a pressure of about .05 atmospheres. The composition of the sample was determined by the X-ray flourescence spectrometer, showing it to be similar to oceanic tholeiitic basalts. The lander survived for 57 minutes (the planned design life was 32 minutes) in an environment with a temperature of 465 degrees C and a pressure of 94 Earth atmospheres.

The High Energy Transient Experiment (HETE) is an international mission led by The Massachusetts Institute of Technology (MIT). Its prime objective is to carry out the first multiwavelength study of gamma ray bursts (GRBs) with UV, X-ray, and gamma ray instruments. A unique feature of the mission is its capability to localise bursts with several arcsecond accuracy, in near real-time aboard the spacecraft. These positions are transmitted to the ground, and picked up by a global network of primary and secondary ground stations (SGS), enabling sensitive follow-up studies. References: 4 .
The Proton launch vehicles Block DM3 fourth stage put the Panamsat PAS 8 into a 6784 km x 35941 km x 17.3 degree transfer orbit. PAS 8 had 24 C-band and 24 Ku-band transponders and was to be located over the Pacific after its R-4D apogee engine manoeuvred the orbit to geostationary altitude and inclination. Geostationary at 166.1 degrees E.
