Mariner With Solar Panels In Launch Position

Flight configuration of Atlas D-Agena B-Mar ner 2 space vehicle (mid-August 1961 to mid-July 1962). To achieve the objectives in the limited time available, it was necessary to make all decisions quickly, to freeze the design at the earliest feasible point, and to meet all schedule milestones on time. An all-out effort was initiated to design, develop, procure, test, and launch the two spacecraft in an 11-mo period. The many associated activities, such as trajectory work, preparation...

Mariner Spacecraft Configuration

Mariner R spacecraft, showing location of scientific experiments As the flight progressed, spacecraft temperatures, especially in the Earth sensor, reached levels higher than predicted. It is evident that these high temperatures occurred, although the flight transducers indicated that the upper thermal shield was performing as designed, and that thermal energy was being adequately distributed throughout the basic hex structure, minimizing case-temperature differences. The louvers...

Mariner Reliability in Flight

Although the Mariner 2 mission was, on the whole, successful, the spacecraft was by no means faultless. Failures occurred in portions of the spacecraft, and design deficiencies were noted. The evidence of a highly reliable spacecraft would be a mission devoid of such design deficiencies and failures. It is, however, a part of good system design to include backup or redundancy provisions to ensure the success of the mission despite certain failures or malfunctions. Considering the extreme weight...

Battery Charge

This was not achieved, however, without some abnormal behavior. Factoring out the abnormal experience, the performance corresponded to that predicted. All power system units operated near or above the upper temperature limit of their design characteristics. Figures 81 to 90 present curves of all the power system temperature measurements, as well as solar panel output, voltage, and current, and battery voltage, current, and charge. Both predicted and telemetered values of current,...
