Third-party evidence for Apollo Moon landings of the Moon landing really is. The NASA-independent "Observatoire de la Côte d'Azur", McDonald, Apache Point, and Haleakalā observatories regularly use the Apollo LRRR. Lick Observatory attempted to detect from Apollo 11's retroreflector while Armstrong and Aldrin were still on the Moon but did not succeed until August 1, 1969. The Apollo 14 astronauts deployed a retroreflector on February 5, 1971, and McDonald Observatory detected it the same day. The Apollo 15 retroreflector was deployed on July 31, 1971, and was detected by McDonald Observatory within a few days. The image on the left shows what is considered some of
Apollo PGNCS Apollo PGNCS The Apollo Primary Guidance, Navigation and Control System (PGNCS) (pronounced "pings") was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as expected, when the spacecraft were behind the Moon, or in case of a communications failure. The Apollo Command Module (CM) and Lunar Module (LM), were each equipped with a version of PGNCS. PGNCS, and specifically its computer, were also the command center for all system inputs from the LM, including the Kollsman Instrument built alignment optical telescope, the radar system, the manual translation and
