Apollo 14 Mission
Surface Operations Overview
During their 33.5 hours on the Moon, the Apollo 14 crew performed two extravehicular activities (EVAs) totaling over 9 hours on the lunar surface. These EVAs covered a total traverse distance of 3.5 kilometers and involved collecting lunar samples at 13 locations, deploying or performing 10 experiments, and examining and photographing the lunar surface. The following map of the landing area shows where these activities took place.
Collecting the Contingency Sample
The contingency sample was taken 8-10 meters from the lunar module near a small crater. The sample was scooped into a bag and transferred to the LM. The contingency sample was collected to ensure that some material from this landing site would be returned to Earth in the event that an emergency required a rapid, unplanned end to the EVA.
Activities at the Lunar Module Site
S-Band Antenna Deployment
The Television Camera Setup
The TV camera was removed from the LM for deployment on the surface. However, during the
transfer, the camera was accidentally pointed at the Sun or the Sun's reflection on the descent
stage and the vision tube apparently burned out. This ended the TV coverage of the lunar surface
Placing the Solar Wind Composition Experiment
The astronauts reported no difficulties in deploying the Solar Wind Composition Experiment. The only difficulty occurred during the retrieval of the apparatus. The foil would only roll up about halfway and had to be manually rolled the rest of the way.
Placing the Flag on the Lunar Surface
Deployment of the Apollo Lunar Surface Experiments Package
The Apollo Lunar Surface Experiments Package (ALSEP) was deployed about 180 meters west of the LM. There was some difficulty locating a level site. After the site was selected, the lunar dust presented some problems for the remainder of the ALSEP deployment. Experiments in this ALSEP were the Passive Seismic Experiment, Active Seismic Experiment, Suprathermal Ion Detector Experiment, Cold Cathode Gauge Experiment, Charged-Particle Lunar Environment Experiment, and the Lunar Dust Detector.

Several components of the ALSEP are shown in this photograph taken during the first Apollo 14 extravehicular activity. The larger object with the antenna is the ALSEP central station. The Active Seismic Experiment mortar assembly is to the left rear of the central station. The Charged Particle Lunar Environmental Experiment is to the right rear of the central station. A portion of the Modular Equipment Transporter can be seen in the left foreground.

Astronaut Alan L. Bean, lunar module pilot, carries the two subpackages of the ALSEP. The subpackages have been left in their collapsed form for easier handling.
|The Apollo Simple Penetrometer
Commander Charles Conrad Jr. aligns the antenna on the central station for the ALSEP. The ALSEP's Lunar Surface Magnetometer is in the foreground. In the center background near Conrad are other ALSEP components.
|Deployment of the Laser Ranging Retroreflector
The Laser Ranging Retroreflector was deployed at a distance of approximately 30 meters west of the Apollo Lunar Surface Experiments Package central station. Leveling and alignment were accomplished with no difficulty.
On the return to the LM from the ALSEP, a number of samples were taken at a site designated station EVA-1. Part of the sampling during this EVA was the comprehensive sample that was taken about 100-125 meters west of the LM. The samples consisted of rock fragments and soil. There was also the bulk sample consisting of scooped soil, taken near the LM, and two football-sized rocks. Some additional panoramic photography was also taken at the LM before the astronauts ended the first EVA.
|The second extravehicular activity (EVA) was a planned geological traverse to Cone Crater, with the objective of sampling material from the rim of this crater. At the crew's request, the EVA was begun 2 hours, 27 minutes earlier than scheduled. All equipment was transported using a small cart, the Modular Equipment Transporter. Due to the difficulty in walking over the rugged terrain, the crew fell behind schedule during the traverse. As a result, several of the planned geology stops were cancelled and the traverse stopped short of Cone Crater's rim. Post-mission analysis of landmarks in photographs indicated that the crew may have been just 20 meters from the crater rim when Mission Control ordered them to return to the lunar module (LM). The crew did not know this during the EVA because of the difficulty in determining their precise location in the rugged terrain. The stops that were made on the traverse are listed below. This EVA lasted 4 hours and 34 minutes, from 3:11 a.m. to 7:45 a.m. EST on February 6. During this time the astronauts traveled approximately 3 kilometers.|
The Geologic Traverse
This station was about 150 meters northeast of the lunar module and 90 meters north of Triplet Crater. The crew collected a double-length core tube and two bags of samples and photographed panoramic sequence 6. They also took the first Lunar Portable Magnetometer measurement.
Station B was about 330 meters northeast of the LM and 65 meters north-northwest of the rim of Weird Crater. The astronauts collected one bag of samples and photographed panoramic sequence 7.
This was an intermediate stop just east of Station B where one bag of samples, a "grab sample," was collected.
Station B1 was a stop for photography, panoramic sequence 8. No samples were collected.
This was another photography-only stop, for panoramic sequence 9.
This was the location for panoramic photography sequence 10. No samples were collected.
This station was located 1.28-1.29 kilometers east-northeast of the lunar module and approximately 95-100 meters southeast of the rim of Cone Crater. Three bags of samples were collected. Panoramic photography for panoramic sequence 11 was taken along with the second portable magnetometer measurement.
Station C1 was about 1.24-1.25 kilometers east-northeast of the LM and 17-30 meters southeast of the Cone Crater rim. Sampling consisted of two bags and a "football-sized rock." Additional photography was also performed.
At this location, 1.21 kilometers east-northeast of the lunar module and approximately 130 meters south of the rim of Cone Crater, the crew collected one bag of samples and took photographs.
This was an intermediate stop near Flank Crater to collect samples.
One bag of samples was collected at Station E.
At Station F, one bag of samples was collected and the astronauts photographed panoramic sequence 12.
Station G was about 230 meters east-southeast of the LM and 50 meters east of the North Triplet Crater rim crest. Sampling included two core tubes, soil, rocks, and a special environmental sample. The astronauts also dug a trench as part of the soil mechanics investigation, and photographed panoramic sequence 13.
This station was 150 meters east of the LM on the north rim crest of North Triplet Crater. One bag of samples was collected and additional photography was performed.
This location was about 70-80 meters northwest of the LM, where additional samples were collected and panoramic sequence 14 was photographed.
Other EVA Activities
Before beginning the traverse, the crew performed some additional panoramic photography near the LM. In addition, a number of close-up stereoscopic photographs were taken on the traverse. There was a side trip to the ALSEP experiment site to realign the central station antenna, and, while there, the astronauts also collected a few samples. Finally, the Solar Wind Collector foil was recovered for return to Earth.
Near the end of the EVA, following completion of the geology traverse and just prior to loading the collected samples into the LM, Alan Shepard attached a 6-iron golf club to the end of a sample collecting tool and took one-handed swings at two golf balls. He joked that the second ball traveled "miles and miles," although it actually traveled only a few hundred meters.
|The Apollo Lunar Surface Close-up Camera
All stereoscopic photographs were taken by Astronaut Shepard during the second traverse. Photographs were taken midway between the LM and Station A, at Station A, again at Station B2, and at the LM just before the film was removed from the camera. Although photographs at other locations had been planned, no additional shots could be taken because of a shortage of time.
|The Lunar Portable Magnetometer
