Lind said an attempt would also be made to capture and bring home a little lunar "air." It is known that the moon has no true atmosphere, but leakage of gas from its interior may have coated its surface with an extremely thin layer of primarily heavier gases. Two high-vacuum containers, each the size of a coffee can, have been provided so that lunar samples can be collected with a minimum of danger of a ospheric contamination.

The moon tools are carried in the modular equipment stowage area, or mesa, between two legs of the lower stage of the LM. When opened, half the mesa drops down, like a very large suitcase with top and bottom compartments, so that its entire interior is accessible to an astronaut on the ground. Inside are two "rock boxes" in his big pocket he will be unable to see the pocket. He will have to find it by feel. Yet his sense of touch will be greatly dulled by his heavy clothing.

One of the first tasks of the astronauts after they open the hatch of the lunar module that lands them on the moon may be to clean off their porch and front steps. Lind pointed out that as the descent stage rocket blasts downward, slowing the bend over and pick up objects off the ground.

Working with difficulty in the very cramped lunar module speed and altitude of planes and now spaceships. The first phase of the National Aeronautics and Space Administration's biosatellite program had these objectives: To discover whether complex organisms could survive space conditions, and to test life support systems. To determine whether complex organisms (dogs and primates) could survive during launch, orbital space flight, reentry and recovery.

To determine the effects of ambient space radiation, and any obvious effect of weightlessness on biological organisms. NASA reported that these studies indicated that man's forming the same work after six weeks of bed rest. It was noted that after only a day or two in a fixed position the deconditioning phenomenon was already evident. Dr. Charles A.

Berry, director of medical research at NASA's manned spacecraft center in Houston, now feels that weightlessness is more of a factor than confinement in producing deconditioning.
