An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit. [ 1 ] The penumbral lunar eclipses on February 20, 2027 and August 17, 2027 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on May 7, 2031 and October 30, 2031 ...
Project LOLA. Project LOLA, or Lunar Orbit and Landing Approach, was a simulator built at the NASA's Langley Research Center to study landing on the lunar surface. Built to aid the Apollo astronauts, it aimed to provide a detailed visual encounter with the Moon's landscape, costing nearly $2 million.
An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit. [1] The penumbral lunar eclipses on June 17, 2038 and December 11, 2038 occur in the next lunar year eclipse set.
An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit. [ 1 ] The penumbral lunar eclipses on January 21, 2038 and July 16, 2038 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on April 5, 2042 and September 29, 2042 ...
The Reduced Gravity Walking Simulator, or Lunar Landing Walking Simulator, was a facility developed by NASA in the early 1960s to study human locomotion under simulated lunar gravity conditions. Located at NASA's Langley Research Center in Virginia, it was designed to prepare astronauts for the Moon landing during the Apollo program .
An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit. [ 1 ] The penumbral lunar eclipses on February 9, 2009 and August 6, 2009 occur in the previous lunar year eclipse set, and the lunar eclipses on April 25, 2013 (partial) and October 18, 2013 ...
Illustrates the range of a lunar period of time or a lunar event, the geological range of a stratigraphic unit, or other ranges on a geological timescale. Intended for use in infoboxes.

A lunisolar calendar was found at Warren Field in Scotland and has been dated to c. 8000 BC, during the Mesolithic period. [2] [3] Some scholars argue for lunar calendars still earlier—Rappenglück in the marks on a c. 17,000 year-old cave painting at Lascaux and Marshack in the marks on a c. 27,000 year-old bone baton—but their findings remain controversial.
