3.   The largest portion of our present knowledge comes from the study of returned lunar materials in laboratories on Earth.

4.   There has been no mention of any way to profit from the use of lunar material.

5.   They therefore are also very efficient at releasing all the trapped solar-wind gases in the lunar material.

6.   This is almost certainly the first practical use of lunar materials to be attempted.
