Neil Armstrong
It has just been reported that Neil Armstrong, the first man to set foot on the Moon, has died at the age of 82.
Neil had very recently undergone surgery to sort out some blocked coronary arteries and it is thought that he died after complications set in from the procedures.
He was commander of the Apollo 11 mission and did his "one small step for man, one giant leap for mankind" bit from the lunar module, Eagle, on the 20th July 1969. Last year he was awarded the Congressional Gold Medal.
RIP Neil.
