Third-party evidence for Apollo Moon landings minus 6 million years. The test was done by a group of researchers headed by Alexander Nemchin at Curtin University of Technology in Bentley, Australia. The detection on Earth of reflections from laser ranging retro-reflectors (LRRRs, or mirrors used as targets for Earth-based tracking lasers) on Lunar Laser Ranging experiments left on the Moon is evidence of landings. Quoting from James Hansen's biography of Neil Armstrong, "": For those few misguided souls who still cling to the belief that the Moon landings never happened, examination of the results of five decades of LRRR experiments should evidence how delusional their rejection
Lunar distance (astronomy) all parties. Before accurate mechanical chronometers, the synchronization event was typically a lunar eclipse, or the moment when the Moon crossed the meridian (if the observers shared the same longitude). This measurement technique is known as lunar parallax. For increased accuracy, certain adjustments must be made, such as adjusting the measured angle to account for refraction and distortion of light passing through the atmosphere. Early attempts to measure the distance to the Moon exploited observations of a lunar eclipse combined with knowledge of Earth's radius and an understanding that the Sun is much further than the Moon. By observing the
