Apollo Experiments


Part I: Lunar Surface Experiments

The lunar surface experiments were of two kinds:

  1. The Apollo Lunar Surface Experiments Package (ALSEP) systems, which were left on the lunar surface by the astronauts and which continued sending telemetry data until turned off Sept. 30, 1977, and
  2. experiments conducted on the lunar surface by the astronauts and returned to earth in the command module.
The dates and lunar coordinates are given in the following listing. The ALSEP-related experiments are listed next, by experiment number, with Apollo mission numbers.

Apollo 12:
The Apollo 12 ALSEP was deployed on November 19, 1969, at latitude 3 degrees 11' S, longitude 23 degrees 23' W in Oceanus Procellarum.
Apollo 13:
Because of service module problems, a lunar landing was not accomplished during the Apollo 13 mission.
Apollo 14:
The ALSEP was deployed on February 5, 1971, at latitude 3 degrees 40' S, longitude 17 degrees 27' W in the Fra Mauro formation.
Apollo 15:
The ALSEP was deployed July 31, 1971, at latitude 26 degrees 06' N, longitude 3 degrees 39' E in the Hadley-Apennine region.
Apollo 16:
The ALSEP was deployed April 21, 1972, at latitude 8 degrees 59' 34" S, longitude 15 degrees 30' 47" E in the Descartes Highlands.
Apollo 17:
The ALSEP was deployed on December 12, 1972, at latitude 20 degrees 09' 55" N, longitude 30 degrees 45' 57" E in the Taurus-Littrow region.

Part II: Lunar Orbital Experiments

Most of the lunar orbital experiments were added to the Apollo program during missions 15, 16, and 17. The objectives of these experiments were to determine and understand regional variations in the chemical composition of the lunar surface, to study the gravitational field of the moon, to determine the induced and permanent magnetic fields of the moon, and to make a detailed study of the morphology and albedo of the lunar surface. These experiments and the missions during which they were performed are listed in the following table.
