AS17-134-20454 (13 Dec. 1972) --- Scientist-astronaut Harrison H. Schmitt is photographed seated in the Lunar Roving Vehicle (LRV) at Station 9 (Van Serg Crater) during the third Apollo 17 extravehicular activity (EVA) at the Taurus-Littrow landing site. This photograph was taken by astronaut Eugene A. Cernan, commander. Schmitt, lunar module pilot, and Cernan explored the moon while astronaut Ronald E. Evans, command module pilot, remained with the Command and Service Modules in lunar orbit.

KENNEDY SPACE CENTER, FLA. -- Astronaut Eugene A. Cernan is lunar module pilot for Apollo 10, scheduled for launch from the nation's spaceport on May 18. Cernan and Apollo 10 Commander Thomas P. Stafford are to detach the lunar module after the spacecraft enters lunar orbit and drop down to within 10 miles of the Moon's pockmarked surface before rejoining John W. Young, command module pilot, orbiting the Moon in the command_service module. The Apollo 10 mission is a dress rehearsal for a manned lunar landing later this year.

KENNEDY SPACE CENTER, FLA. -- Astronaut Eugene A. Cernan is lunar module pilot for the Apollo 10 lunar orbit mission scheduled for launch from KSC on May 18. Cernan and Apollo 10 commander Thomas P. Stafford will detach the lunar module from the command_service module and drop to within 10 miles of the lunar surface before rejoining John W. Young, command module pilot, in the parent spacecraft.

S72-48892 (September 1972) --- Two members of the prime crew of the Apollo 17 lunar landing mission ride in a Lunar Roving Vehicle trainer during lunar surface extravehicular activity simulation training at the Kennedy Space Center (KSC), Florida. Astronaut Eugene A. Cernan, commander, is seated in the left-hand seat. Scientist-astronaut Harrison H. Schmitt, lunar module pilot, is on Cernan's right.

AS17-146-22351 (7-19 Dec. 1972) --- This view, photographed by astronaut Eugene A. Cernan, shows a large boulder which was discovered by astronauts Cernan and Harrison H. Schmitt during one of their space walks. The astronauts later pointed out light clasts on the boulder. South Massif is in the background. Tracks left by the Lunar Roving Vehicle (LRV) can be seen near foreground. While astronauts Cernan, commander, and Schmitt, lunar module pilot, descended in the Lunar Module (LM) "Challenger" to explore the Taurus-Littrow region of the moon, astronaut Ronald E. Evans, command module pilot, remained with the Command and Service Modules (CSM) "America" in lunar orbit.

S72-55064 (11 Dec. 1972) --- Astronaut Eugene A. Cernan operates the Apollo Lunar Surface Drill during the first Apollo 17 extravehicular activity (EVA) at the Taurus-Littrow landing site, in this black and white reproduction taken from a color television transmission made by the RCA color TV camera mounted on the Lunar Roving Vehicle. Cernan is the commander of the Apollo 17 lunar landing mission. Astronaut Ronald E. Evans, command module pilot, remained with the Apollo 17 Command and Service Modules in lunar orbit while astronaut Cernan and scientist-astronaut Harrison H. Schmitt, lunar module pilot, descended in the Lunar Module to explore the moon.

S66-31665 (3 May 1966) --- Astronaut Eugene A. Cernan, pilot of the Gemini-9 spaceflight, participates in extravehicular training under zero-gravity conditions aboard a KC-135 aircraft. Here, he is donning the Astronaut Maneuvering Unit (AMU) backpack after egressing a Gemini mock-up. The AMU backpack is mounted in the adapter equipment section of the mock-up. Cernan wears an extravehicular activity (EVA) life support system chest pack. Cernan will use the AMU during his scheduled EVA on the Gemini-9 mission. The KC-135 flew a parabolic curve to create the weightlessness condition for training purposes. Photo credit: NASA

S66-34075 (3 June 1966) --- Prime crew for the Gemini-9A spaceflight, astronauts Thomas P. Stafford (front), command pilot, and Eugene A. Cernan, pilot, leave the suiting trailer at Launch Complex 16 in full spacesuits during prelaunch countdown. Photo credit: NASA

S72-44420 (8 June 1972) --- Astronaut Eugene A. Cernan, commander of the Apollo 17 lunar landing mission, prepares to remove a traverse gravimeter training mock-up from a Lunar Roving Vehicle for deployment during lunar surface extravehicular activity simulations at the Kennedy Space Center (KSC), Florida.

S69-35502 (June 1969) --- Astronaut Eugene A. Cernan (left), lunar module pilot of the Apollo 10 lunar orbit mission, confers with astronaut Edwin E. Aldrin Jr. during an Apollo 10 postflight de-briefing session. Aldrin is the lunar module pilot of the Apollo 11 lunar landing mission.

The Apollo 17 space vehicle towers over the astronauts it will launch to the moon on December 6, 1972 from KSC. The astronauts, L-R, Harrison H. Schmitt, Ronald E. Evans and Eugene A. Cernan participated in a walkdown of the emergency route at Launch complex 39A.

The Apollo 17 Space Vehicle sits poised beneath a full moon on Launch Pad 39A during launch countdown. Astronauts Eugene A. Cernan, Commander Ronald Evans, Command Module Pilot and Dr. Harrison "Jack" Schmitt, Lunar Module Pilot, will be the crew for the sixth U.S. manned Lunar landing mission.
