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 .
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.
The Bell Aerosystems Lunar Landing Research Vehicle (LLRV, nicknamed the Flying Bedstead) [1] was a Project Apollo era program to build a simulator for the Moon landings.The LLRVs were used by the FRC, now known as the NASA Armstrong Flight Research Center, at Edwards Air Force Base, California, to study and analyze piloting techniques needed to fly and land the Apollo Lunar Module in the Moon ...
The Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...
The lunar phases and librations in 2019 in the Northern Hemisphere at hourly intervals, with music, titles, and supplemental graphics Simulated views of the Moon over one month, demonstrating librations in latitude and longitude. Also visible are the different phases, and the variation in visual size caused by the variable distance from Earth.
New Moon. Click here to read the full article. The new moon marks the beginning of the lunar cycle. During this phase, the moon is hidden from sight, taking its leave from the center stage.
Sketch of a circumlunar free return trajectory (not to scale), plotted on the rotating reference frame rotating with the moon. (Moon's motion only shown for clarity) In orbital mechanics, a free-return trajectory is a trajectory of a spacecraft traveling away from a primary body (for example, the Earth) where gravity due to a secondary body (for example, the Moon) causes the spacecraft to ...
The synodic month, i.e. the mean period for the phases of the Moon. Now called "System B", it reckons the synodic month as 29 days and (sexagesimally) 3,11;0,50 "time degrees", where each time degree is one degree of the apparent motion of the stars, or 4 minutes of time, and the sexagesimal values after the semicolon are fractions of a time ...
