CAPE CANAVERAL, Fla. (AP) – Apollo 11 astronaut Michael Collins has returned to the exact spot where he and two other astronauts flew to the moon 50 years ago. At NASA’s invitation, Michael Collins spent the golden anniversary Tuesday morning at Kennedy Space Center’s Launch Complex 39A in Florida. He marked the precise moment – 9:32 a.m. on July 16, 1969 – that their Saturn V rocket departed on humanity’s first moon landing. Buzz Aldrin was an unexplained no-show. Mission commander Neil Armstrong – who took the first lunar footsteps – died in 2012. Collins says he wishes Aldrin and Armstrong could have shared the moment Tuesday at the pad. The 88-year-old astronaut was interviewed live on NASA TV. The event kicks off a week of celebrations marking each day of Apollo 11’s eight-day voyage.
