The difference between day and night on the Moon. The terminator is just to the west of the crater Gambart, which is at the extreme north in the photograph. This view is representative of the lunar surface as seen by the crew as they crossed the terminator twice every orbit. The Apollo 13 landing site is located in the highland region in the shadow area of the photograph. (NASA photograph AS12-50-7438) Figure 1-9. The difference between day and night on the Moon.

Instrument Description and Performance

A seismometer consists simply of a mass, free to move in one direction, that is suspended by means of a spring (or a combination of springs and hinges) from a framework. The suspended mass is provided with damping to suppress vibrations at the natural frequency of the system. The framework rests on the surface whose motions are to be studied and moves with the surface. The suspended mass tends to remain fixed in space because of its own inertia while the frame moves around the mass. The...

Pyroxene Pic Info

Studied in dry nitrogen cabinets handled by people in LRL crew reception area for 20 min. Studied in dry nitrogen cabinets handled by people in LRL crew reception area for 20 min. vacuum (generally on the order of 106 torr). The documented sample, contingency sample, totebag sample, and core tubes were opened and studied in. dry-nitrogen glove cabinets. Approximately 50 g of core-tube material and 450 g of fines and rock chips from the documented and selected samples were committed for...

Alsrc

The ALSRC contained approximately 0.5 atm when returned to the LRL. All of these samples were processed in dry nitrogen. The ALSRC contained approximately 0.5 atm when returned to the LRL. All of these samples were processed in dry nitrogen. tubes were driven at two locations one was a double-core tube. Two special samples, the gas analysis sample container GASC and the lunar environment sample container LESC , which were designed to be sealed individually, were collected table 12-V . All these...
