Passive Seismometer Experiments Package  (PSEP)

A component of the Early Apollo Scientific Experiments Package (EASEP) that was deployed on the Moon by the Apollo 11 Crew. PSEP uses three long-period seismometers and one short-period vertical seismometer for measuring meteoroid impacts and moonquakes. Such data will be useful in determining the interior structure of the moon; for example, does the moon have a core and mantle like Earth?

The PSEP was sensitive enough to pick up the footsteps of astronauts Neil Armstrong and Buzz Aldrin as they walked on the moon.

NASA No.  69-H-130

30 January 1969

The Passive Sismometer Experiments Package (PSEP) is a self-contained 100 pound seismic station with its own transmitter, powered by solar cells. It will detect very slight motions of the lunar crust and interior to help clarify the origin and structure of the Moon.

The PSEP was demonstrated at the Lunar Surface Training Area in Building 9 a MSC by Ron Redick, human Factor Engineering Division of Bendix Aerospace, Ann Harbor, Michigan, Bendix is the prime NASA contractor for the Lunar Experiments Packages.

Ron is about to pull the latch of the experiment package. This will allow the solar panels to expand and after he attaches the transmitter antenna array the set-up will be complete.

Apollo 11 returned to Earth at 12:50 p.m. today but KSC personnel at the Unified S-Band Site maintained contact with the Passive Seismic Experiments Package still in operation at Tranquillity Base. Inspecting data tape from the PSEP erected on the Moon by the Apollo 11 crew are Joseph Morrison, seated, and Wayne Cocayne, standing. Monitoring data at an adjacent console is Richard Hansen. The PESP was activated on the lunar surface to keep delicate instruments tuned in on meteorite strikes and moonquakes.

Apollo Lunar Surface Experiments Package  (ALSEP)

A combination of experiments taken to a site sufficiently far from the LM was collectively called the ALSEP. There was a central processing station to which all of the peripheral experiments (and the RTG) were attached. It provided power distribution, communications with Earth, etc. The rest of the experiments connected to this station by cables. Power for all of the experiments was provided by the Radioisotope Thermoelectric Generator (RTG). Each experiment was assigned its own name and number. and is considered separately in the database. With several of the packages in place on the Moon, networks provided more information than any one could provide. For example, the seismometer network provide from ALSEPs emplaced by Apollo 12, 14, 15, and 16 enabled the location of impacts and moonquakes to be determined. The network of 3 LSMs enabled the study of solar wind plasma movement by detection of its contained magnetic field. The ALSEP on Apollo-17 carried different instruments once the networks had been established by earlier flights.

10 October 1969

The Apollo Lunar Surface Experiments Package (ALSEP) system consists of two sub-packages and a fuel cask assembly. One sub-package contains three of the experiment subsystems, the data subsystem, and a portion of the electrical power subsystem. The other sub-package contains the astronauts hand tools that they used for geological sampling, one of the experiment subsystems and the remainder of the electrical power subsystem. The fuel cask assembly is the container for the radio active fuel capsule. The two ALSEP sub-packages will be mounted within the scientific equipment bay of the Lunar Module for their trip to the Moon.

10 October 1969

ALSEP Passive Seismic Experiment - This experiment will give information about the physical properties of the Moon. It will determine the frequency of moonquakes and measure approximate azimuth and distance to seismic epicentres. The location and frequency of meteorite impacts on the Moon also can be observed. The experiment separates movements into three speed ranges; long period signals are detected on three axes with amblitude sensitive sensors; tidal signals are detected with the long period sensors.

ALSEP Lunar Ionosphere Detector. This measures characteristics of positive ions at the lunar surface. Its lower energy limit makes it different from the other particle experiments in that it may give information about the lunar atmosphere as well as the low energy portion of the solar wind. The effect of electric fields near the lunar surface can also be observed.

Charged Particle Lunar Environment Experiment.

The CPLEE consists of a box supported by legs. It contains 2 similar physical charged-particle analyzers oriented in different directions for minimum exposure to the ecliptic path of the sun. Each detector package had six particle detectors (five provided information about particle energy distribution, and the sixth provided high sensitivity at low particle fluxes), 2 different programmable high-voltage power supplies, and other circuitry.

NASA No.  70-H-244

February 1970

The Heat Flow Experiment measures the lunar temperature profile at depths up to 10 feet and the value of the Moon's thermal conductivity over the same depth. From these measurements, information may be deduced regarding the net outward flux of heat from the Moon's interior and the radioactive content of the Moon's interior compared to that of the Earth's mantle.
