A specialized world map created under the direction of the Department of Defense by the Aeronautical Chart and Information Center (ACIC) of the United States Air Force for the National Aeronautics and Space Administration (NASA). This chart was designed specifically for the Apollo 9 mission, which took place in 1969.
Marked as the 1st Edition and dated January 31, 1969, the chart was lithographed by ACIC in February 1969. Its primary purpose is to display the ground track coordinates of the Apollo 9 spacecraft as it orbited Earth, covering revolutions 17 through 158. These coordinates are printed on the reverse side of the chart, providing essential information for mission control personnel and astronauts during the mission.
The lower margin of the chart contains a note that highlights its importance in supporting the Apollo 9 mission, a crucial step in NASA's ambitious plan to land astronauts on the Moon. The Apollo Earth Orbit Chart (AEO)-9 played a significant role in ensuring accurate tracking and effective coordination of activities during the mission, contributing to the overall success and safety of the Apollo program.
Apollo 9 was a critical manned spaceflight mission in NASA's Apollo program, launched on March 3, 1969. The mission's primary objectives were to test the lunar module (LM) in Earth's orbit and assess its docking capabilities with the command and service module (CSM). Astronauts James McDivitt, David Scott, and Russell Schweickart successfully carried out a ten-day mission, proving that the LM and CSM could dock and undock, an essential maneuver for the upcoming lunar landing missions. The success of Apollo 9 played a pivotal role in paving the way for Apollo 10 and the historic Apollo 11 lunar landing, making it an indispensable step towards achieving NASA's goal of putting humans on the Moon.
