Apollo 17 (America)

 1972-096A



    Apollo 17 Crew

  • CDR Commander Eugene Cernan, Capt. USN

  • CMP Command Module Pilot Ronald Evans, Cdr USN

  • LMP Lunar Module Pilot Harrison `Jack' Schmitt, Ph.D., NASA

Apollo CSM 114 was the CSM for the Apollo 17 mission. The crew named it America. Apollo 17 was launched at 0533 on 1972 Dec 7 from Launch Complex 39A at Kennedy Space Center. The Saturn V SA-512 delivered Apollo 17 to a 169 x 178 km Earth orbit at 0544.

The S-IVB reignited for translunar injection at 0845. Half an hour later the CSM separated from the Spacecraft Lunar Adapter, the four SLA panels ejected into space. The crew rotated the CSM and came back in to dock with the exposed Lunar Module. The transposition and docking maneuver was complete at 0929, and at 1018 the assembled Apollo 17 spaceship separated from the S-IVB stage.

The crew made a single midcourse correction on the way to the Moon, and a few hours before arrival jettisoned the panel covering the instruments in the SIM (Scientific Instrument Module). The SIM carried the Lunar Sounder, a synthetic aperture radar system operating at 5, 15 and 150 MHz.

Apollo 17 entered lunar orbit with a firing of the CSM's SPS engine at 1947 on Dec 10. On Dec 11, Cernan and Schmitt transferred to the LM, leaving Ron Evans as the sole crewmember aboard America.

At 1721 on Dec 11 the LM Challenger undocked and began its descent to the Moon. Evans changed America's orbit to 100 x 130 km and concentrated on lunar orbit science operations. Two more orbit changes were made on Dec 14, and early on Dec 15 Challenger, back in space, approached the CSM. Challenger docked with America at 0110:15 and Cernan and Schmitt returned to the CM with their cargo of lunar rock. The LM was undocked at 0451 on Dec 15.

The voyage home began at 2335 on Dec 16 with the transearth injection burn. At 2027:40 on Dec 17 the cabin was depressurized. The CMP exited the hatch and translated along the Service Module to the SIM bay, retrieving the panoramic, mapping, and lunar sounder film and data cassettes in three trips. The LMP stood in the hatch and assisted. The hatch was open for 45 minutes, and the CM was depressurized for 1:05:44, until 2133:24. (Another source gives 1:07:18).

On Dec 19 the Service Module was jettisoned and the Command Module began its reentry, with the nominal start of reentry at 1911:38. America splashed down in the Pacific at 1925, and was recovered by the USS Ticonderoga.
