Aldrin urged Congress and the American people to use the memory of Apollo 11 as inspiration to prepare for a space journey to Mars.
"Apollo 11 was a symbol of what a great nation and a great people can do if we work hard and work together," he said.
"America, do you still dream a great dream? Do you still believe in yourself?" he went on to ask. "I call on the next generation and our political leaders to give this answer: Yes We Can!"
Kind of ride on Obama's coat tails eh? But Buzz is right. WE Can go to MARS! We got to the Moon 40 years ago. Let's get started and get to Mars soon!
