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
Origin of the Moon and incorporated any small pre-existing satellites of Earth, which would have shared the Earth's composition, including isotopic abundances. The geology of the Moon has since been more independent of the Earth. Although this hypothesis explains many aspects of the Earth–Moon system, there are still a few unresolved problems, such as the Moon's volatile elements not being as depleted as expected from such an energetic impact. Another issue is lunar and Earth isotope comparisons. In 2001, the most precise measurement yet of the isotopic signatures of moon rocks was published. Surprisingly, the Apollo lunar samples carried an isotopic signature identical to
