Each display included Moon dust from Apollo 11 and flags, including one of the Soviet Union, taken along by Apollo 11. The rice-sized particles were four small pieces of Moon soil weighing about 50 mg and were enveloped in a clear acrylic button about as big as a United States half-dollar coin. This acrylic button magnified the grains of lunar ...
The U.S. was not able to reach the Moon with the Pioneer and Ranger programs, with fifteen consecutive U.S. uncrewed lunar missions from 1958 to 1964 failing their primary photographic missions. [19] [20] However, Rangers 4 and 6 successfully repeated the Soviet lunar impacts as part of their secondary missions. [21] [22]
On 20 July 1969 Apollo 11 landed on the Moon, and Neil Armstrong became the first person to walk on the Moon. At the same time another mission, the robotic sample return mission Luna 15 by the Soviet Union, was in orbit around the Moon, becoming together with Apollo 11 the first ever case of two extraterrestrial missions being conducted at the ...
The 14-foot-tall lander then spent six days cruising more than 620,000 miles to reach the moon. ... The moon's south polar region has long been tantalizing for scientists because water ice is ...

The Eagle lunar lander — carrying the first humans to reach the moon — descends during the Apollo 11 mission on July 20, 1969. This is a composite image comprised of two separate shots ...
The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
Occurring behind the Moon, out of contact with the Earth, this engine burn put the spacecraft into orbit around the Moon. It was the first test of the new procedures for using both SPS during a long burn. Loss of signal (LOS) was at 78 hours, 23 minutes and 31 seconds GET as the spacecraft went behind the Moon as seen from the Earth.
