LUNAR SURFACE VIEW – LM Descent Monitoring Chart – Sheet 2, 16 July 1969 Launch Date, Landing Site No. 2, Edition 1. Aeronautical Chart and Information Center, USAF for NASA, 1969. A superb visual presentation of the views from Armstrong and Aldrin's Lunar Module windows as they piloted Eagle to land on the Moon. A chart showing the Eagle's ground track, SIGNED and INSCRIBED by Buzz ALDRIN with his communications during landing. Aldrin's flight inscription marks the points he made his original radio communications, as follows from left to right: “Go …. At 4 Minutes,” “…Descent Looks Good," and “Sequence Camera Coming On.” Created from Lunar Orbiter satellite photography, this chart marks the events beginning 4 minutes before Eagle's Power Descent Initiation (PDI) at the far right and counts down at one minute intervals. The actual point of the PDI is labeled close to the center of the chart. At 20 second intervals, an increasing time count is labeled until T + 4 minutes after the start of PDI to the far left. During the flight period on this chart, Eagle’s windows were pointed down toward the Moon which allowed Armstrong and Aldrin to view these lunar features outside. Grid patterns are printed in black marking every 30 minutes of latitude and longitude. The planned LM descent path center line and viewing limits are printed in white. These events were performed and monitored while Armstrong and Aldrin were using Page 9 of the Apollo 11 LM Timeline Book . Lithographed chart, 12.5 by 48 inches.
