'An Even Better Friend': 45 Years Since the Apollo 17 Decision (Part 2)

Standing near a huge boulder, overlooking the scenic grandeur of the Taurus-Littrow valley, Jack Schmitt became the first - and so far only - professional geologist to visit another world. His selection as a member of the Apollo 17 crew came at the end of a long and difficult process, which saw him overlooked for an assignment time and time again...and eventually resulted in Joe Engle losing his own seat on a lunar voyage.

'I Didn't Feel Any Obligation': 45 Years Since the Apollo 17 Decision (Part 1)

Forty years after Apollo 17, Jack Schmitt remains the only professional geologist to practice his art on another world.

As Project Apollo wore on, the intensity of lobbying by the scientific community to get geologist-astronaut Jack Schmitt to the Moon increased. Originally assigned to the Apollo 15 backup crew, Schmitt might have flown Apollo 18, prior to a sweeping cancelation of the final missions in the program. Photo Credit: NASA
