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 13 more immediate and visible warnings of anomalies. Because Apollo 13 followed the free-return trajectory, its altitude over the lunar far side was approximately greater than the orbital altitude on the remaining Apollo lunar missions. The Moon was almost at apogee during the mission (as it also was during the flights of Apollo 10 and Apollo 15), which also increased the distance from the Earth. The combination of the two effects ensures that Apollo 13 holds the absolute altitude record for a manned spacecraft, reaching a distance of from Earth on 7:21 pm EST, April 14, 1970.
