<br /><br />
Some LPOD readers give talks about the Moon to astronomy clubs, school kids and anyone else <br />
who will listen. Probably most of the images they show are telescopic ones that they took or maybe <br />
that appeared in LPOD. Now your slides can be augmented with professionally made diagrams <br />
from the Center for Lunar Science and Exploration at the Lunar and Planetary Institute. As an <br />
example, this image, based on the work of lunar scientst Jim Head, shows a cross-sectional view <br />
of the Orientale Basin. In many ways this looks like the cross-section of a lunar complex crater with<br />
massive wall slumps, but the big difference is the green stuff. That is the lunar mantle that has <br />
risen under the basin into the original or transient cavity created by the ejection of excavated <br />
crustal rocks. The mantle is made of denser rocks so that their rise closer to the surface causes <br />
a mascon - a positive mass anomaly that is detected by the gravity pull on orbiting spacecraft. <br />
In addition to the <em>Classroom Illustrations</em> set that this diagram comes from there are [http://www.lpi.usra.edu/nlsi/multimedia/ other] slide<br />
sets and illustrations to use, as well as LPI's exhaustive [http://www.lpi.usra.edu/lunar/lunar_images/ collection] of lunar maps and photos from<br />
spacecraft missions. <br />
