He has logged more than 5,000 hours flying time with more than 4,800 hours in jet aircraft and over 200 jet aircraft landings.
Cernan subsequently served as backup pilot for Gemini 12 and as backup lunar module pilot for Apollo 7.
On his second space flight, he was lunar module pilot of Apollo 10, May 18-26, 1969, the first comprehensive lunar orbital qualification and verification flight test of an Apollo lunar module. He was accompanied on the 248,000 nautical sojourn to the moon by Thomas P. Stafford (spacecraft commander) and John W. Young (command module pilot). In accomplishing all of the assigned objectives of this mission, Apollo 10 confirmed the operations performance, stability, and reliability of the command/service module and lunar module configuration during translunar coast, lunar orbit insertion, and lunar module separation and descent to within eight nautical miles of the lunar surface. The latter maneuver involved employing all but the final minutes of the technique prescribed for use in an actual lunar landing, and allowed critical evaluations of the lunar module propulsions sytems and rendezvous and landing radar devices in subsequent rendezvous and redocking maneuvers. In addition to demonstrating that man could navigate safely and accurately in the moon's gravitational fields, Apollo 10 photographed and mapped tentative landing sites for future missions.
Cernan's next assignment was backup spacecraft commander for Apollo 14.
He made his third space flight as spacecraft commander of Apollo 17,the last scheduled manned mission to the moon for the United States, which commenced at 11:33 P.M. (CST), December 6, 1972, with the first manned nighttime launch, and concluded on December 19, 1972. With him on the voyage of the command module America and the lunar module Challenger were Ronald Evans (command module pilot) and Harrison H. "Jack" Schmitt (lunar module pilot). In maneuvering Challenger to a landing at Taurus-Littrow, located on the southeast edge of Mare Serenitatis, Cernan and Schmitt activated a base of operations from which they completed three highly successful excursions to the nearby craters and the Taurus mountains, making the Moon their home for over three days. This last mission to the moon established several new records for manned space flight that include: longest manned lunar landing flight (301 hours 51 minutes); longest lunar surface extravehicular activities (22 hours 6 minutes); largest lunar sample return (an estimated 115 kg (249 lbs.));; and longest time in lunar orbit (147 hours 48 minutes). While Cernan and Schmitt conducted activities on the lunar surface, Evans remained in lunar orbit aboard the America, completing assigned work tasks requiring geological observations, handheld photography of specific targets, and the control of cameras and other highly sophisticated scientific equipment carried in the command module SIM-bay. Evans also completed a one-hour, six-minute extravehicular activity on the transearth coast phase of the return flight, successfully retrieving three camera cassetes and completing a personal inspection of the equipment bay area. Apollo 17 ended with a splashdown in the Pacific Ocean approximately 0.4 miles from the target point and 4.3 miles from the prime recovery ship USS TICONDEROGA.
Captain Cernan has logged 566 hours and 15 minutes in space, of which more than 73 hours were spent on the surface of the moon, and was the last man of Apollo to leave his footprints on the surface of the moon.
In September 1973, Cernan assumed additional duties as Special Assistant to the Program Manager of the Apollo Spacecraft Program at the Johnson Space Center. In this capacity, he assisted in the planning, development, and evaluation of the joint United States/Soviet Union Apollo-Soyuz mission, and he acted for the program manager as the senior United States negotiator in direct discussions with the USSR on the Apollo-Soyuz Test Project.
On July 1, 1976, Captain Cernan retired after over 20 years with the U. S. Navy. He concurrently terminated his formal association with NASA. Cernan joined Coral Petroleum, Inc., of Houston, Texas, as Executive Vice President-International. His responsibilities were to enhance Coral's energy related programs on a worldwide basis.
In September 1981, Captain Cernan started his own company, The Cernan Corporation, to pursue management and consultant interests in the energy, aerospace, and other related industries. Additionally, he has been actively involved as a co-anchorman on ABC-TV's presentations of the flight of the shuttle.
Captain Cernan was the second American to have walked in space, having spanned the circumference of the world twice in a little more than two and one half hours. He was one of the two men to have flown to the moon on two occasions, and as commander of the last mission to the moon, Apollo 17, had the privilege and distinction of being the last man to have left his footprints on the surface of the moon.
