50 Years Ago: Two Months Until Apollo 14

In November 1970, workers at NASA’s Kennedy Space Center (KSC) put the finishing touches on the Saturn V rocket for the Apollo 14 Moon landing mission before rolling it out to its seaside launch pad. The Apollo 14 crew of Commander Alan B. Shepard, Command Module Pilot (CMP) Stuart A. Roosa, and Lunar Module Pilot (LMP) Edgar D. Mitchell, along with their backups Eugene A. Cernan, Ronald E. Evans, and Joe H. Engle rehearsed aspects of their mission in spacecraft simulators. Shepard and Mitchell practiced their lunar surface excursions planned for the Fra Mauro Highlands during a geology field trip to Arizona and several simulations at KSC. The Apollo 15 crew completed two geology field trips and received a training version of the lunar rover they planned to drive during their July 1971 Moon landing mission to the Hadley-Apennine landing site.

After stacking the Apollo 14 spacecraft atop its Saturn V rocket in the Vehicle Assembly Building (VAB), workers mounted the Launch Escape System (LES) tower atop the spacecraft on Nov. 8. The LES is used only in an emergency during the first two minutes of powered flight to lift the spacecraft and crew to safety should there be a serious malfunction with the rocket.

The next morning, on the third anniversary of Apollo 4, the first flight of a Saturn V rocket, the Apollo 14 Saturn V began its slow rollout of the VAB, completing the 3.5-mile trip to Launch Pad 39A in about 6 hours. Shepard, Roosa, and Mitchell watched the rollout and even walked along with the rocket for a brief time.  Roosa then answered reporters’ questions about the upcoming mission. Once the rocket arrived at the pad, workers continued to prepare it and the spacecraft for the flight. They installed a spare battery and a third oxygen tank in the spacecraft’s Service Module, modifications resulting from the accident that crippled the Apollo 13 spacecraft on its way to the Moon in April 1970. They installed an accumulator device in the rocket’s second stage to prevent the pogo-effect vibrations experienced during the Apollo 13 launch resulting in an early engine shutdown. In early December, engineers began spacecraft integrated systems testing, leading to the Flight Readiness Test planned for Dec. 17-18.

Shepard and Mitchell, accompanied by a team of geologists, completed their final geology training field trip on Nov. 16 to the Black Mesa crater field near Cottonwood, Arizona. To make the terrain more lunar-like, workers blasted 14 new craters before the crew’s arrival, following erosion of earlier craters by heavy rains. Shepard and Mitchell completed their walking traverse while using the MET to carry their tools and samples. They collected rock samples, including photographing and describing them while in communication with Mission Control in Houston, where a science support team listened and analyzed the incoming information and advised the astronauts on further actions.

Shepard and Mitchell, as well as backups Cernan and Engle, practiced for the two planned lunar surface extravehicular activities (EVAs). During the first EVA, the astronauts planned to unfold the MET, stowed on the side of the LM, to help them carry their tools and collected samples. Other activities for the first EVA included setting up the suite of scientific experiments and deploying the American flag. The astronauts trained for these tasks in the Manned Spacecraft Operations Building (MSOB).

The tasks for the second EVA involved longer traverses, aided by the MET, and collecting the bulk of the geology samples. Using the “thumper” device, the astronauts caused minor seismic events that sensitive instruments recorded. The resulting data would inform scientists about the internal composition of the lunar crust.

Apollo 15

Preparations continued for the July 1971 Apollo 15 mission, the first with expanded capabilities including a longer lunar surface stay time of three days and the use of the Lunar Roving Vehicle (LRV) to expand the range of astronauts’ geology excursions. The Grumman Aircraft Corporation delivered the two stages of the Lunar Module (LM) to KSC, with the ascent stage arriving on Nov. 6 and the descent stage 10 days later.  Workers in the MSOB began LM systems tests on Nov. 30. The Boeing Co. delivered the LRV 1-G trainer to the Marshall Space Flight Center on Nov. 17 for initial testing, following which it was delivered to the Manned Spacecraft Center, now NASA’s Johnson Space Center in Houston, on Dec. 16 for astronaut training.

The training for the Apollo 15 crew of Commander David R. Scott, CMP Alfred M. Worden, and LMP James B. Irwin, and their backups Richard F. Gordon, Vance D. Brand, and Harrison H. “Jack” Schmitt focused on the enhanced scientific aspects of their mission. The ambitious Hadley-Apennine landing zone, the first Apollo site away from the Moon’s equator, featured the 8,000-foot high Apennine Mountains and the Hadley Rille, a 60-mile long, half-a-mile wide and 600-foot deep sinuous canyon. During a two-day geology field trip Nov. 19-20 to the San Gabriel Mountains in California, Scott, Irwin, Gordon, and Schmitt used cameras and sample collection equipment to practice collecting and photo documenting samples. A lengthier field trip to the islands of Hawaii and Oahu Dec. 5-12 familiarized the crew with the geology of volcanic terrain. The astronauts used the Grover as a stand-in for the LRV during both trips to execute longer traverses than could be possible by walking.
