ALSEP was a collection of scientific instruments deployed by astronauts on the moon to conduct experiments. These experiments provided valuable information about the moon, and the data was transmitted back to Earth through the central station, one of the package's components. ALSEP could be operated remotely from Earth, and the data and measurements it collected offered important insights into the moon's seismic activity, magnetic field, and ionosphere. (00:08) An astronaut wearing an Apollo spacesuit walks in a simulated lunar environment. (00:18) A mock lunar lander, similar to the Lunar Module Eagle from the Apollo 11 mission, is shown. (00:22) The Apollo Lunar Surface Experiments Package (ALSEP) is located in the scientific equipment bay of the lander. (00:41) The central station is displayed. (00:50) The Radioisotope Thermoelectric Generator (RTG), the power source for ALSEP, is seen. (01:12) The fuel cask on the lunar module is shown. (01:21) The fuel capsule can be removed by tilting it down. (01:29) The tool for removing the power cell is displayed. (01:38) The fuel capsule provides fuel for one year. (01:58) The technician carefully removes the isotopic cylinder. (02:05) This tool creates a distance between the fuel and the astronaut. (02:10) The fuel capsule is placed in the generating system. (02:16) The cell is locked into the RTG. (02:26) A barbell-type device is used to carry both the Central Station and the RTG. (02:31) The technician carries the device. (02:47) The passive seismometer, which assesses seismic activity on the moon, is shown. (03:05) It is set up 300 feet away from the lunar module. (03:14) The technician sets up the solar wind experiment (SWS). (03:26) The SWS analyzes solar plasma on the moon and its electromagnetic properties. (03:44) The Suprathermal Ion Detector Experiment (SIDE), used to investigate the ions on the moon, is shown. (04:07) The technician uncovers the antenna assembly, which will transmit the data back to Earth. (04:24) The antenna pedestal is visible. (04:31) A leveling bubble is shown. (04:41) The antenna is attached to the gimbal. (04:55) The antenna points towards the center of Earth's rotation. (05:03) The magnetometer, used to measure the moon's magnetic fields, is displayed. (05:30) The technician carries the experiment. (05:45) He extends the folded sensor arms. (06:10) He aligns the sensors. (06:21) The technician returns to the central station. (06:28) He raises the sun shield to protect the central station. (06:44) He checks the equipment. (06:58) The central station can receive commands from Earth. (07:05) A close-up of the central station is shown. We encourage viewers to add comments and, especially, to provide additional information about our videos by adding a comment!
