Orbital Science Experiments

The Apollo 14 Command and Service Modules in lunar orbit, as viewed from the Lunar Module.

In addition to their studies on the lunar surface, the Apollo 14 crew performed several studies of the Moon from lunar orbit.

The S-Band Transponder Experiment measured regional variations in the Moon's gravitational acceleration.

The Bistatic Radar Experiment measured scattering of radar waves from the lunar surface.

In addition to lunar studies, several other experiments were performed to study the space environment.

Other Apollo 14 Science Experiments

In addition to their lunar studies, the Apollo 14 crew performed several experiments intended to explore various aspects of the space environment. These experiments were performed primarily during the journeys to and from the Moon. The following links connect to sites at the Johnson Space Center (JSC) and the National Space Science Data Center (NSSDC) for further information about these experiments.

The Window Meteoroid experiment studied impacts on the windows of the Apollo 14 Command Module to obtain information about the size distribution of very small micrometeorites.

The Composite Casting Experiment studied the solidification of immiscible compositions in microgravity.

The Electrophoresis Demonstration studied the separation of organic molecules in an electric field.

The Heat Flow and Convection Demonstration studied convective flow and heat transport driven by surface tension.

The Liquid Transfer Demonstration studied how different types of tank design influenced the pumping of liquids between tanks in microgravity.

The Light Flashes Experiment studied light flashes seen by the crew that are related to charged particles in space.

Apollo 14 Dataset Descriptions
The National Space Science Data Center (NSSDC) provides data and information on Apollo experiments upon request to individuals or organizations resident in the United States. The same services are available to scientists outside the United States through the World Data Center A for Rockets and Satellites. Normally, a charge is made for the requested data to cover the cost of reproduction and the processing of the request.

Catalog of Apollo Experiment Operations
This Johnson Space Center site catalogs each experiment and equipment item deployed or operated on the lunar surface during the Apollo program. It summarizes some of the general problems encountered with these experiments and provides guidelines for the design of future lunar surface experiments.

Surface Science Experiments

The Apollo Lunar Surface Experiment Package deployed at Apollo 14.

In addition to their geologic studies, the Apollo 14 crew performed several experiments on the lunar surface. The results of some of these experiments were either radioed to Earth by the crew or returned to Earth for laboratory analysis.

The Soil Mechanics Investigation studied the properties of the lunar soil.

The Lunar Portable Magnetometer measured the strength of the Moon's magnetic field.

The Solar Wind Composition Experiment collected samples of the solar wind for analysis on Earth.

Other experiments were deployed by the crew and then monitored from Earth by radio telemetry after the crew departed. This group of experiments was termed the Apollo Lunar Surface Experiment Package (ALSEP). Each experiment was connected by a cable to the ALSEP central station, which provide radio communication to Earth and electrical power from a radioisotope thermal generator. Some of these experiments continued to return data until September 1977, when the entire ALSEP network was turned off due to lack of funding for the ground support team.

The Passive Seismic Experiment detected lunar "moonquakes" and provided information about the internal structure of the Moon.

The Active Seismic Experiment provided information about the structure of the upper 100 meters of the lunar regolith.

The Laser Ranging Retroreflector measured very precisely the distance between the Earth and Moon.

The Cold Cathode Gauge measured the abundance of gases in the lunar atmosphere.

The Suprathermal Ion Detector Experiment studied the lunar ionosphere.

The Charged Particle Lunar Environment Experiment measured plasmas around the Moon.

The Lunar Dust Detector studied the effects of lunar dust on the operation of the experiment package.
