Lunar Laser Ranging RetroReflector (LRRR) array placed and photographed on Moon July 31, 1971, by Commander David "Dave" Randolph Scott (born June 6, 1932) during Apollo 15 mission
NASA's ongoing Lunar Laser Ranging experiments measure distances between Earth and Moon via retroreflectors placed on Moon during Apollo program (missions 11, 14,15).

Observing the moon: lower of two green beams is from Lunar Reconnaissance Orbiter's dedicated tracker; other laser originates from ground system at NASA Goddard Space Flight Center. Both beams are pointed at LRO orbiting Moon.

Giant Impact Hypothesis, also known as Big Splash or The Theia Impact: Moon formed from debris from Mars-sized protoplanet -- named Theia for Greek Titan mother of moon goddess Selene by Alexander Halliday in 2000 -- obliquely grazing Earth 4.5 bya.
"Planetary Smash-Up"; artist's concept shows Moon-sized celestial body slamming at great speed into a body the size of Mercury.

First image of the far side of the Moon was obtained by Soviet spacecraft Luna 3, or E-2A No.1, at 03:30 UT on October 7, 1959, at distance of 63,500 kilometers.

happynutritionist, Watching that first moon landing via TV is one of those happy historic events which definitely warrants a great big plus mark in the lives of lucky viewers.
But me, too, I agree that the others need to be remembered as well.
Excellent photos, with the passage of years, we forget some of the moon landings, we never forget the first, I remember where I was when watching it on TV, but the others become a blur and shouldn't be.
