Astronaut John Young  who walked on the moon and was the first to fly into space six times  died Friday night at 87.
In a statement  acting NASA Administrator Robert Lightfoot said  Young  died from complications from pneumonia. He called  Young  NASA's "most experienced astronaut."
“Today  NASA and the world have lost a pioneer " Lightfoot said. " Astronaut John Young 's storied career spanned three generations of spaceflight; we will stand on his shoulders as we look toward the next human frontier."
A former fighter pilot   Young  started  his  career with NASA in 1962.  His  first flight as an astronaut came in March 1965 aboard the Gemini 3 with fellow astronaut Gus Grissom.  He  went to the moon in May 1969 aboard Apollo 10 and again in April 1972 on Apollo 16.
 Young  had gone into space as apart of the Gemini  Apollo and space shuttle programs  the only NASA astronaut to be a part of all three  Lightfoot said.
