First edition Lunar Module Orbit Monitor Chart used in training for the Apollo 13 mission, folded and taped so as to form a 10-leaf booklet, measuring 10.5 x 8, issued for potential launch dates of April 11 or May 10, 1970, SKB 32100083-373, March 1, 1970, marked in blue felt tip, “LM 8.” This training chart, which covers the LM's ground track from liftoff through the first complete lunar orbit, is identical to the LM Orbit Monitor chart that was planned to be used post LM liftoff during Apollo 13. The landing area at Fra Mauro can be viewed near the back of the booklet, and the LM's Ascent Stage ground track is shown by a white line running down the center of the chart. Timing marks run alongside, and major craters and topographical features are also labeled. Of particular note is the "LM 8" notation written on the chart ID label. This is, of course, incorrect given that the Apollo 13 LM was ‘LM 7.’ This notation was intended as a joke to be played on Apollo 14 astronaut Shepard to see how long it would take him to realize he was looking at an Apollo 13 chart. The consignor notes that it did not take the Apollo 14 commander very long to notice the inconsistency. In fine condition. From the collection of Dan Schaiewitz, who worked as Extravehicular Crew Training Engineer at KSC.
