This video looks at a NASA Goddard Instrument Field Team deployment to the Kilbourne Hole maar crater in New Mexico. The scientists came here to test hand-held geological instruments that may one day be used by astronauts exploring the Moon, Mars or even an asteroid. As a part of this data collection, astronaut Barry E. "Butch" Wilmore, a former commander of the International Space Station, conducted simulated moonwalks in the area. Retired Apollo 17 astronaut Harrison "Jack" Schmitt was also on-site at Kilbourne Hole – revisiting some of the very spots where he once trained. This excursion to the Kilbourne Hole crater was a part of the RIS4E (Remote, In Situ and Synchrotron Studies for Science and Exploration) project led by Stony Brook University, and featured members from Johnson Space Center and the University of Texas El Paso.
