His death was reportedly caused by complications from a recent heart-bypass surgery.
Armstrong started his NASA career as a test pilot in Ohio. He was an aerospace engineer and a professor. During the Apollo 11 mission in 1969, he became the first man to ever set foot on the moon.
He became the first to successfully dock two vehicles in space in 1966 when he piloted the Gemini 8 mission.
Armstrong’s famous words will resonate with Americans forever, “That’s one small step for man, one giant leap for mankind.”
