The final space shuttle mission touched down 15 years ago today, marking the end of NASA's 30-year Space Shuttle program.
As the world's first reusable spacecraft, the shuttles accomplished so much over 135 missions. From building and supporting the @Space_Station, to launching and servicing missions a variety of commercial and scientific satellites such as @NASAHubble, to conducting groundbreaking research, it left an enduring legacy as a platform for exploration, science, and international cooperation.
One giant leap for mankind
History was made on July 20, 1969, when Apollo 11's Neil Armstrong and Buzz Aldrin became the first to set foot on the Moon.
For more than 5 decades, the total number of moonwalkers has remained at 12. NASA will change that with Artemis IV.
57 Years ago today humanity first set foot on the Moon.
I was just five years old when Apollo 11 landed and Neil Armstrong stepped down with those immortal words, "That's one step for man, one giant leap for mankind." That moment changed my life forever and Neil became one of my heroes. To the Apollo pioneers: thank you for opening the door to the stars!
