Alan Bean's training-used star chart marked "RT Data, CSM Deorbit, Star Chart, July 15, 1975 Launch," 16 x 8, prominently signed across the front in gold ink, "Alan Bean." The chronopaque chart traces the "Deorbit" path in yellow, and labels the various stars and constellations useful in celestial navigation. The reverse of the chart, marked "October 1974," has circular north and south constellation charts marked "Right Ascension," along with a table on the right side labeled "S/C X-Axis Position With Time in Local Horizontal Pitch Attitude." In fine condition, with a tiny tear to the upper right edge. This chart was used by Alan Bean while training as backup crew commander for the Apollo-Soyuz Test Project.
