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) 205,000 miles) during the Precambrian Era; 2,500 million years BP. The giant impact hypothesis, a widely accepted theory, states that the Moon was created as a result of a catastrophic impact between Earth and another planet, resulting in a re-accumulation of fragments at an initial distance of (15,000 miles). In this theory, the initial impact is assumed to have occurred 4.5 billion years ago. Until the late 1950s all measurements of lunar distance were based on optical angular measurements: the earliest accurate measurement was by Hipparchus in the 2nd century BC. The space age marked a turning point when the
