When we go back to the Moon, we'll need to employ geophysics to study its interior and will glean important insights into understanding the origin of the Earth-Moon system. In the process, we'll also learn valuable information to help people live and work on the lunar surface. For example, we can characterize the seismic hazard and find resources of interest in the subsurface.
Back in January 2010, I joined a small group of like-minded terrestrial and planetary geophysicists at the LunarGeo2010 meeting, which was held at Arizona State University. The LROC Outreach team was there interviewing some meeting participants on camera for their LRO Live! education and public outreach project. My interview video surfaced on the web yesterday:
It was an honor to be included in the LROC Live! video project along with others such as Astronaut Harrison "Jack" Schmitt (a geologist who holds the record for EVA time on the Moon), Astronaut Drew Feustel (who fixed Hubble and is the only current geophysicist-astronaut), and Barbara Cohen (who heads the U.S. component of the International Lunar Network). Dr. Schmitt gave a very well-thought-out rationale why we should return to the Moon that I'd like to share with you now:
