Apollo 12 Makes Second Moon Landing
The second crewed lunar landing demonstrated NASA's refined precision in targeting specific sites and expanded the scope of scientific work on the Moon's surface.
Summary
Following the success of Apollo 11 earlier that year, NASA launched Apollo 12 on November 14, 1969, with astronauts Charles Pete Conrad, Alan Bean, and Richard Gordon aboard. The mission aimed for a precision landing near the Surveyor 3 probe that had arrived on the Moon in 1967. Despite lightning strikes during launch that temporarily disrupted systems, the spacecraft reached lunar orbit without further incident. On November 19, the lunar module Intrepid touched down in the Ocean of Storms just 535 feet from Surveyor 3. Conrad and Bean conducted two EVAs, deploying scientific instruments, collecting samples, and retrieving parts from the Surveyor probe before returning safely to Earth on November 24.
Context
By late 1969 the Apollo program had shifted from its initial focus on achieving the first lunar landing to demonstrating repeatable operational capabilities. Apollo 11's success in July had met the primary political goal set by President Kennedy, but planners recognized that future missions would need to land near sites of particular scientific interest rather than broad, safe plains. Apollo 12 therefore received a more demanding objective: a pinpoint touchdown beside the unmanned Surveyor 3 spacecraft that had been sitting in the Ocean of Storms since April 1967.
What Happened
Apollo 12 lifted off from Kennedy Space Center on November 14, 1969, carrying Commander Charles "Pete" Conrad, Command Module Pilot Richard F. Gordon, and Lunar Module Pilot Alan L. Bean. Thirty-six seconds after launch the Saturn V rocket was struck by lightning, knocking out several spacecraft systems; a second strike seconds later compounded the problem. Engineer John Aaron in Mission Control quickly identified the issue and directed the crew to switch the signal-conditioning equipment to auxiliary power, restoring critical functions and allowing the flight to continue.
Aftermath
The command module Yankee Clipper splashed down in the Pacific Ocean on November 24, 1969, and was recovered by the USS Hornet. Conrad and Bean returned with 34 kilograms of lunar samples, photographs, and components removed from Surveyor 3, including its camera and scoop arm. Engineers and scientists examined the retrieved parts to assess the effects of nearly 31 months of exposure to the lunar environment.
Legacy
Apollo 12 proved that astronauts could land within a few hundred feet of a preselected target, a capability essential for the more geologically focused landings that followed. The mission's success with the Apollo Lunar Surface Experiments Package and the retrieval of Surveyor hardware informed planning for Apollo 13 through 17 and contributed data still referenced in lunar science today.
Why It Matters
Apollo 12 demonstrated improved landing accuracy and expanded lunar science capabilities, paving the way for subsequent Apollo missions focused on geological exploration and setting the stage for more ambitious crewed spaceflight programs.
Related Questions
How close did Apollo 12 land to Surveyor 3?
The lunar module Intrepid touched down about 535 feet from the Surveyor 3 probe, demonstrating the precision required for future targeted landings.
What problems occurred during the Apollo 12 launch?
Two lightning strikes shortly after liftoff disrupted spacecraft electronics; the issue was resolved when the crew switched the signal-conditioning equipment to auxiliary power on advice from Mission Control.
What did the Apollo 12 crew bring back from the Moon?
Conrad and Bean collected 34 kilograms of lunar rock and soil samples and retrieved parts from Surveyor 3 for analysis of long-term exposure to the lunar environment.
Why was Apollo 12 considered a success for future missions?
It proved that NASA could achieve pinpoint landings near specific scientific targets, validated new surface experiments, and provided operational experience that shaped later Apollo landings.
