8.14 EXPERIMENT M3C-4, OPTICAL COMMUNICATIONS The objectives of experiment NEC-4 were to evaluate an optical communications system, to evaluate the flight crew as a pointing element, and to probe the atmosphere using an optical coherent radiator cutside the atmosphere. The experiment equipment consisted of a gallium-arsenide laser transmitter (flight hardware), and three instrumented ground sites, each equipped with a flashing beacon and capable of collecting and demodulating coded optical...

Info

The performance of the environmental control system (ECS) was generally good throughout the mission. All parameters were as expected except those reported herein. 5.1. .1 Crewman comfort. - During the first hours of the mission, both crew members wore the pressure suit with the hoods and gloves off. Thermal comfort was generally good however, the crew reported being slightly warm when the B pumps were providing coolant. These pumps deliver coolant at approximately one-half the rate of the A...

Weather Conditions

The weather conditions in the launch area at Cape Kennedy were satisfactory for all operations on the day of the launch, December 1965. Surface weather observations In the launch area taken at 2 30 p.m. e.s.t. (19 3 G.m.t. ) were as follows Cloud coverage 5 10 altocumulus at 16 000 ft Wind direction, Wind velocity, Visibility, miles Pressure, in. Temperature, Dew point, Relative humidity, percent 73 The weather observations in the recovery area taken at 14 05 G.m.t., December 18, 1965, onboard...

Flight Trajectories

The launch and orbital trajectories referred to as planned are either preflight calculated nominal trajectories from references 8 and 9 or trajectories based on nominal outputs from the real-time computer complex (RTCC) and planned attitudes and sequences as determined in real time by the auxiliary computer room (ACR). The actual trajectories are based on the Manned Space Flight Network tracking data and actual attitude and sequences as determined by airborne instrumentation. The Patrick Air...

Actual Mission

A comparison of the planned and actual mission is shown in figure 4.1-1. Lift-off of the Gemini VII vehicle occurred on December 4, 1965, at 19 30 03 702 G.m.t. Lift-off was expected to occur at 19 30 00 G.m.t., but the range sequencer, which times the ignition signal to the launch vehicle, was not properly synchronized with the range countdown clock. For precision lift-off timing, it had been planned that the sequencer would be synchronized 3 seconds ahead of the range clock and the range...

Yaw Steering In Ascent

Performance of the GEV stage I and stage II guidance systems was satisfactory throughout the powered flight and resulted in placing the spacecraft into an acceptable orbit. 5.2.5.1 Programmed guidance.- The programmed guidance was within acceptable limits as shown in table 5.2-IV. As discussed in section 4, a nominal trajectory was flown. The errors at EECO were 132 ft sec high in velocity, 2016.0 feet high in altitude, and 0.13 low In flight-path angle. 5.2.5.2 Radio guidance.- The guidance...

Gemini Spacecraft

A detailed description of the basic structure and major systems of the first complete production Gemini spacecraft (spacecraft 2) is provided in reference 2. All spacecraft flown subsequently are similar, with the exceptions noted herein and in references 5, and 7-Because the spacecraft 7 configuration closely resembles that of spacecraft 5 (ref. 5), only the significant differences between these two spacecraft are included In this report. These differences are summarized in table 3.1-1. The...
