This particular flag had flown in the Mission Operations Control Room (MOCR) in Houston during Apollo and was noticeably larger than the flags deployed on the previous missions.⁣ ⁣ You may notice the support rod in the top part of the flag. The support rod ensured that the flag was extended and visible in photographs, despite there being no wind on the lunar surface to make the flag wave.⁣ ⁣ Six U.S. flags in total were planted on the lunar surface, one during each Apollo mission.
