APOLLO 13 As Planned - Jim Lovell on Landing, EVAs, ALSEP, 3rd Stage Impact & Fra Mauro (1970/04)

Jim Lovell describing in detail the planned Apollo 13 mission, along with training and actual landing and EVA footage (taken from Apollo 14, that landed on 13's intended location). He goes into great detail about the 3rd stage lunar impact, ALSEP experiments, mission milestones and differences regarding previous Apollo missions. Apollo 13's primary mission objectives were to: "Perform selenological inspection, survey, and sampling of materials in a preselected region of the Fra Mauro Formation. Deploy and activate an Apollo Lunar Surface Experiments Package. Develop man's capability to work in the lunar environment. Obtain photographs of candidate exploration sites." Apollo 13's designated landing site was near Fra Mauro crater; the Fra Mauro formation was believed to contain much material spattered by the impact that had filled the Imbrium basin early in the Moon's history. Dating it would provide information not only about the Moon, but about the Earth's early history. Such material was likely to be available at Cone crater, a site where an impact was believed to have drilled deep into the lunar regolith. Apollo 11 had left a seismometer on the Moon, but the solar-powered unit did not survive its first two-week-long lunar night. The Apollo 12 astronauts also left one as part of its ALSEP, which was nuclear-powered. Apollo 13 also carried a seismometer (known as the Passive Seismic Experiment, or PSE), similar to Apollo 12's, as part of its ALSEP, to be left on the Moon by the astronauts. That seismometer was to be calibrated by the impact, after jettison, of the ascent stage of Apollo 13's LM, an object of known mass and velocity impacting at a known location. Other ALSEP experiments on Apollo 13 included a Heat Flow Experiment (HFE), which would involve drilling two holes 3.0 metres (10 ft) deep. This was Haise's responsibility; he was also to drill a third hole of that depth for a core sample. A Charged Particle Lunar Environment Experiment (CPLEE) measured the protons and electrons of solar origin reaching the Moon. The package also included a Lunar Atmosphere Detector (LAD) and a Dust Detector, to measure the accumulation of debris. The Heat Flow Experiment and the CPLEE were flown for the first time on Apollo 13; the other experiments had been flown before. To power the ALSEP, the SNAP-27 radioisotope thermoelectric generator (RTG) was flown. Developed by the U.S. Atomic Energy Commission, SNAP-27 was first flown on Apollo 12. Since Lovell and Haise were to undertake longer traverses than on the earlier missions, the tool carrier which the Apollo 12 astronauts had hand-carried was expanded, given two wheels, and dubbed the Modular Equipment Transporter. For the first time, red stripes were placed on the helmet, arms and legs of the commander's A7L spacesuit. This was done as after Apollo 11, those reviewing the images taken had trouble distinguishing Armstrong from Aldrin, but the change was approved too late for Apollo 12. ========================================= A special thanks to the channel supporters (   / retrospacehd   ): Bill Hurley Gary Smith Ryan Hardy Scott Manley ======================================== #apollo13 #nasa #JimLovell
