Before moon landing, astronauts learned geology in Arizona
1+ day, 22+ hour ago (81+ words) FLAGSTAFF, Ariz. (AP) — Before Neil Armstrong and Buzz Aldrin knew they would be the first to walk on the moon, they took crash courses in geology at the Grand Canyon and a nearby impact crater that is the most well-preserved…...
On 2 August 1971, near the end of Apollo 15’s final moonwalk, David Scott stood before a television camera holding a 1.32-kilogram geological hammer in one hand and a 30-gram falcon feather in the other. He released them together, and in the Moon’s near-vacuum they struck the dust simultaneously—dramatically demonstrating what Galileo had predicted nearly four centuries earlier.
4+ hour, 15+ min ago (503+ words) Apollo 15 turned a geological tool and a falcon feather into a televised demonstration of equal gravitational acceleration in the Moon’s near-vacuum....
