"We came all this way to explore the Moon, and the most important thing is that we discovered the Earth" –Bill Anders, Apollo 8 astronaut

"Earthrise," one of the most powerful photos in @nasa’s history, was taken by Anders #OTD in 1968 as the Apollo 8 crew orbited the Moon.

#OTD in 1964, NASA's SR-71 Blackbird made its 1st flight.

The SR-71 was designed to cruise at Mach 3.2 and at altitudes up to 85,000 ft, making it ideal for high-speed, high-altitude @NASAaero research.

#OTD in 2011, we discovered Kepler-20e, the first planet beyond our solar system smaller than Earth. In all, we've confirmed six exoplanets in the system orbiting a Sun-like star more than 900 light-years from Earth. https://exoplanets.nasa.gov/resources/91/kepler-20e-the-smallest-exoplanet-artists-concept/

Splashdown!

After 12 days and 14 hours in space, the #Apollo17 astronauts splashed down in the Pacific Ocean at 2:25 pm EST #OTD in 1972. It was the longest of all the Apollo missions with the most samples retrieved and photos taken. #Apollo50th
