Recreating moon craters in Arizona
Today’s Video of the Day from the USGS describes how a training ground was developed for Neil Armstrong and Buzz Aldrin to prepare for landing on the moon.
The astronauts needed a place on Earth which matched the cratered surface of the moon. Experts set out to transform a region of ancient lava fields in northern Arizona.
Beginning in 1967, the USGS used hundreds of pounds of dynamite to blast holes across the fields that would resemble craters.
