- Apollo's ALSEPS
- Soil Mechanics Investigation
- measured properties of lunar soil
- allowed scientists to compare lunar soil to Earth soil, proving origin of moon
- Solar Wind Composition Experiment
- collected samples of solar particles using sheets of paper, like flypaper
- used to determine danger of solar wind to astronauts
- found that solar wind is mainly hydrogen
- Passive Seismic Experiment
- detected "moonquakes" to show how geologically active the moon is
- gave information about internal structure
- no geological activity found
- Laser Ranging Retrofractor
- mirror on moon's surface
- scientists fired laser at mirror, used reflection to calculate exact distance
- LCROSS
- not really an ALSEP
- spacecraft that was crashed into Cabeus crater near South Pole
- proved existence of ice on moon
- found Cabeus's mass could be 5% water
- Soil Mechanics Investigation
