US astronaut John Young who has flew to the moon twice and commanded the first ever space shuttle mission has passed away at age 87.
Agency chief Robert Lightfoot said in a statement, “Today, Nasa and the world have lost a pioneer.”
John Young was the only person to have flown missions to space on the Gemini, Apollo and space shuttle programmes.
John Young retired in 2004 after a 42-year long career. Nasa said he died on Friday after catching severe pneumonia.
