GRUMMAN APOLLO LUNAR MODULE—TRACKING LIGHT COVER ASSEMBLY

CONTRACT NO. NAS 9-1100. MFD BY GRUMMAN AIRCRAFT ENGRG CORP. BETHPAGE, N.Y. US FS CODE 26512" and "SET-PROTECTIVE, LIGHT COVERS. PART NO. LDW420-42301-1-1. SERIAL NO. 3.

A crucial piece of the Lunar Module (LM), the Cover Assembly protected the flashing tracking light which was mounted onto the front of the LM. Designed to make it easier for the Command Module (CM) Pilot to see the LM, the tracking light had a total life of 30 hours, and flashed at the rate of 60 flashes per minute. the tracking light had numerous other functional and design requirements, including being compatible for use with CSM scan telescope sextant optics during darkside lunar and earth operations.
