Scientific paper

The paper describes how moon rocks, Antarctic meteorite fragments, and cosmic dust grains are stored and handled at NASA's Johnson Space Center. A piece of rock that is to be studied must be removed by geologists using Neoprene gloves from the nitrogen-filled storage compartment where it sits wrapped in Teflon. If the rock has never been out of the compartment before, it is bathed in nitrogen before being studied. The procedures used to store and process meteorite fragments are similar to those for moon rocks but somewhat less stringent since the fragments have already been exposed to the earth's environment. NASA has about 2000 cosmic dust grains which it obtains from the stratosphere and which in total weigh about two millionths of a gram. They must be handled with glass rods five microns in diameter and are stored in ultraclean conditions. Funding problems may force NASA to discontinue much of its curatorial activity.
