Legendary astronaut Buzz Aldrin, the second man to walk on the moon, has been cheering on the Artemis II mission this week. Buzz became an iconic figure when he became the second man to set foot on the moon's surface after Neil Armstrong during the Apollo 11 mission in 1969. Armstrong died in 2012. Mr Barber credits Buzz with saving his life when he met him at a meeting of Alcoholics Anonymous in December 2001. 'He wants people to know he's doing OK.'
