It was 35 years ago today that the world watched as Neil Armstrong uttered the famous line: "It's one small step for man, one giant leap for mankind." With that, the Apollo Eleven astronaut stepped off the "Eagle" lunar module and became the first man to walk on the moon. He was joined by crew mate Buzz Aldrin. President Bush earlier this year set a goal of returning to the moon by 2020. He has proposed developing a new spacecraft to carry Americans to the moon and to establish a long-term base there as a springboard to Mars and beyond. Some critics say Bush's goal is too ambitious and too expensive.
