“The three brave astronauts of Apollo 11 … took the first small steps of our giant leap into the future,” Obama said in a statement.
On July 20, 1969, Armstrong and Aldrin landed on the moon’s surface while Collins remained in orbit. Armstrong, the first to step onto the soft, powdery turf, uttered the famous sentence, “That’s one small step for man, one giant leap for mankind.” (Armstrong, by the way, says that's wrong -- that he said one step for “a man,” a claim some speech-analyzing scientists support.)
“It was a seminal moment not just in our country’s history, but the history of all humankind,” Obama said in his statement.
Though the Apollo 11 mission may hold an important spot in American history, the 47.5 pounds of lunar rock the crew brought back are still helping to shed fresh light on the moon and our solar system. Just recently, scientists who analyzed fragments gathered by the Apollo 11, 12 and 16 missions found evidence for a violent collision that may have birthed the moon.
Nostalgia aside, Buzz Aldrin says there’s no point in going back to the moon; humans should head to Mars instead, he says in an interview with the co-stars of the film “Earth to Echo.”
