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
Colonization of the Moon in the Solar System to Earth. While some Earth-crosser asteroids occasionally pass closer, the Moon's distance is consistently within a small range close to 384,400 km. This proximity has several advantages: There are several disadvantages to the Moon as a colony site: Russian astronomer Vladislav V. Shevchenko proposed in 1988 the following three criteria that a lunar outpost should meet: While a colony might be located anywhere, potential locations for a lunar colony fall into three broad categories. There are two reasons why the north pole and south pole of the Moon might be attractive locations for a human colony.
