Liftoff! #Apollo11 lifted off July 16, 1969, at 9:32 am EDT, setting off on its history-making journey to land humans on the Moon. This landmark mission inspired people around the world as we witnessed the accomplishment of a seemingly impossible task. ▶️ apolloinrealtime.org/11/

It's no coincidence the first space shuttle was named Enterprise rather than Constitution. After a letter-writing campaign by Trekkies, President Ford directed NASA to use the name of the starship. 📷 Gene Roddenberry and the #StarTrek cast at Enterprise's rollout, Sept 1976

60 feet (18 m) taller than the Statue of Liberty! The #Apollo11 Saturn V rocket stands ready for launch on Pad 39A at @NASAKennedy in this view from above from July 1969. The 363 ft (111 m) tall space vehicle would produce 7,600,000 lbs (34,500,000 newtons) of thrust on launch.

The #Apollo11 crew gazed back at Earth #OTD in 1969 as they made their way to the Moon. Most of Africa and portions of Europe and Asia are visible. Watch Apollo 11's TV broadcast from their "happy home" from July 17, 1969: apolloinrealtime.org/11/?t=034:01:30

NASA was always ahead of the curve 📷 Before the word "selfie" was even thought of, Buzz Aldrin took the first EVA selfie in November 1966 during the Gemini XII mission! #NationalSelfieDay go.nasa.gov/3xhzzQ9

In early 1969 Jack A. Kinzler was responsible for designing a flagstaff for the American flag to be planted on the Moon by the #Apollo11 astronauts and having it “fly” in the airless environment. Read Kinzler's oral history: go.nasa.gov/3XV9ocI 📸 David McGraw demonstrates

The space shuttle's grand finale, STS-135 🙌 Space shuttle Atlantis' launched from @NASAKennedy #OTD in 2011 for the final mission of the shuttle program. Read about Chris Ferguson, Doug Hurley, Sandy Magnus and Rex Walheim's mission to the @Space_Station go.nasa.gov/460yVn6

Space shuttle Endeavour as seen from the @Space_Station 15 years ago today.

Before leaving the Moon, Apollo 15 astronaut Dave Scott performed an experiment #OTD in 1971, dropping a hammer and feather simultaneously in the Moon's airless environment. See the result for yourself ⬇️

.@NASAVoyager 1 took this image of the Earth and Moon in the same frame, the first ever of its kind, #OTD in 1977. The spacecraft, which began its exploration mission of the outer solar system and beyond two weeks earlier, captured this scene from 7.25 million miles away.

Today marks 65 years since the first powered flight of the rocket-powered X-15 aircraft. In the 9-minute flight, Crossfield reached a speed of Mach 2.11 (1,393 mph) and an altitude of 52,341 feet. 📘 The significance of this historic flight: go.nasa.gov/47vzvKe
