 NASA training required the astronauts to have an in-depth knowledge of volcanic rocks and formations, something they expected to encounter on the lunar surface. A number of the astronauts, including each of the three participants of the Apollo 11 mission, flew into Kingsley Field at various dates and times and made their way northward to explore volcanic features near Gilchrist and around the Bend area. Those who attend the showing today are encouraged to bring a blanket or chairs for seating.
