'Astronauts: Charles "Pete" Conrad, Jr., Richard F. Gordon, and Alan L. Bean

Launch date: November 14, 1969

Man's second journey to the Moon is for science. The first EVA includes setting up Apollo Lunar Surface Experiments Package (ALSEP) for the return of scientific data. The second EVA includes a geological traverse and the inspection of Surveyor 3, an unmanned spacecraft that landed on the Moon in 1967. A solar eclipse is recorded, findings to-date are summarized, and commentaries by noted scientists are included.'

Apollo 12 was the sixth manned flight in the United States Apollo program and the second to land on the Moon (an H type mission). It was launched on November 14, 1969 from the Kennedy Space Center, Florida, four months after Apollo 11. Mission commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. The landing site for the mission was located in the southeastern portion of the Ocean of Storms. Unlike the first landing on Apollo 11, Conrad and Bean achieved a precise landing at the site of the Surveyor 3 unmanned probe, which had landed on April 20, 1967... On one of two moonwalks, they visited the Surveyor, and removed some parts for return to Earth. The mission ended on November 24 with a successful splashdown...

Apollo 12 launched on schedule from Kennedy Space Center, during a rainstorm. It was the first rocket launch attended by an incumbent US president, Richard Nixon. Thirty-six-and-a-half seconds after lift-off, the vehicle triggered a lightning discharge through itself and down to the earth through the Saturn's ionized plume. Protective circuits on the fuel cells in the service module falsely detected overloads and took all three fuel cells offline, along with much of the CSM instrumentation. A second strike at 52 seconds after launch knocked out the "8-ball" attitude indicator. The telemetry stream at Mission Control was garbled. However, the Saturn V continued to fly correctly...

Once in earth parking orbit, the crew carefully checked out their spacecraft before re-igniting the S-IVB third stage for trans-lunar injection. The lightning strikes had caused no serious permanent damage...

The Apollo 12 mission landed on an area of the Ocean of Storms that had been visited earlier by several unmanned missions (Luna 5, Surveyor 3, and Ranger 7). The International Astronomical Union, recognizing this, christened this region Mare Cognitum (Known Sea). The Lunar coordinates of the landing site were 3.01239 S latitude, 23.42157 W longitude...

To improve the quality of television pictures from the Moon, a color camera was carried on Apollo 12 (unlike the monochrome camera that was used on Apollo 11). Unfortunately, when Bean carried the camera to the place near the lunar module where it was to be set up, he inadvertently pointed it directly into the Sun, destroying the SEC tube. Television coverage of this mission was thus terminated almost immediately...

Apollo 12 successfully landed within walking distance of the Surveyor 3 probe. Conrad and Bean removed pieces of the probe to be taken back to Earth for analysis...

Astronauts Conrad and Bean also collected rocks and set up equipment that took measurements of the Moon's seismicity, solar wind flux and magnetic field, and relayed the measurements to Earth. The instruments were part of the first complete nuclear-powered ALSEP station set up by astronauts on the Moon to relay long-term data from the lunar surface. The instruments on Apollo 11 were not as extensive or designed to operate long term...

Yankee Clipper returned to Earth on November 24, 1969, at 20:58 UTC (3:58pm EST, 10:58am HST) in the Pacific Ocean, approximately 500 nautical miles (800 km) east of American Samoa.

Public domain film from NASA, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).
