Apollo astronaut Buzz Aldrin lays out plan for Mars colonization in talk at CU-Boulder
'Humans need to explore, push beyond current limits just like we did 45 years ago'
Aldrin, 85, spoke before a packed house Tuesday at Macky Auditorium on the University of Colorado's Boulder campus.
"America must be the world leader in human space flight," he said. "There is no other area that clearly demonstrates American innovation and enterprise than human space flight."
Aldrin made history with Neil Armstrong on July 20, 1969, when the two men became the first humans to step foot on the moon as part of the Apollo 11 mission. In total, they spent 21 hours on the lunar surface gathering 46 pounds of moon rocks. Some 600 million people watched the historic scene on television.
