Professor Lee Silver: The original rock star teacher How do you get a group of test pilot/engineers interested in a bunch of rocks? How can you teach these hard-nosed astronauts to be geologist detectives around rocks and soil, especially on the surface of the Moon? For some time the Apollo astronauts (and would-be geology students) had been bombarded lectures that did not excite them. This had been a nagging problem for NASA as they prepared for the Moon landings. After all, one cannot spend billions of dollars going to our nearest pictures. Given the chance to spend a week proving his teaching methods and the absolute need for good planetary science on Apollo, Silver took a party of astronauts on a Orocopia Mountains. With the beautiful Orocopias at their feet, Silver’s students including James Lovell, Fred Haise, John Young, Charlie Duke and Jack Schmitt, entered a new and beautiful world of geological discovery. Silver began organising further cross country investigative acumen and sharpness akin to a test pilot’s that spoke the Interpreting each other’s detailed descriptions each of the astronauts became quick students in geological observation. Under Silver’s tutelage, their innate curiosity ran wild, collecting a variety (or a “suite”) of rock samples each one telling a line in the story about the evolution of the Orocopia Mountains. Silver imposed time and sample limits on collecting would face on the Moon and their rock collections became more the actual missions. Observing and sampling within the exposed strata of geological time on the Earth, the Apollo astronauts, observation, were prepared to tell the story of the Moon. began on Apollo, Silver himself was in the back-room of Mission Control steering the geology ground teams and acting as a back seat driver for the lunar roving astro-geologists on the Moon. Dave Scott and Jim Irwin had been their Apollo 15 mission, a piece of the primordial lunar crust that would prove the Moon’s age. On August 1, 1971 on Hadley Delta, Scott radioed back to the ground that he and Irwin Lee Silver points out some geological observations to his astro-geologists in training, Charlie Duke and John Young.

He began the “meat part” of the Apollo missions, but not seeing where he had collected the rocks from, there was no detailed context to their story. Enter Caltech Professor of Geology Lee Silver. As an Apollo lunar sample investigator, Silver had been invited by his old student Harrison “Jack” Schmitt to meet with James Lovell and Fred Haise (assigned to Apollo 13) to discuss teaching the astronauts www.RocketSTEM .org same language and spread among his Apollo apprentices. Soon after, further astronauts David Scott and James Irwin whose are attributable to Professor Silver’s teachings. Using the Earth’s natural environment as a stand in for the Moon’s was a masterstroke. The new geology students practiced dress rehearsals of their missions, standing by Lunar Module substitutes (trees) and describing the 360 degree landscape views as a geologist would. rock would later prove to be 4.5 billion years old giving rise to the widely accepted theory that a Mars sized body had collided with the Earth spinning off matter that later formed the Moon. “hitting a home run” which validated his supreme teaching efforts to embed science within the Apollo missions. Were it not for Lee Silver, the Moon’s story and relationship with the Earth would still be relatively unknown. His unique and exciting teaching methods imbued a sense of urgent of science, always looking to push the boundaries of knowledge and follow the observational evidence wherever it leads. 33 33
