"As an Apollo astronaut, I know full well the importance of always exploring new frontiers and tackling new challenges as we explore space. The simple truth is that we have already been to the Moon - some 40 years ago. What this nation needs in order to maintain its position as the 21st century leader in space exploration is a near-term focus on lowering the cost of access to space and on developing key, cutting-edge technologies that will take us further and faster - while expanding our opportunities for exploration along the way."
Why Mars? Buzz Aldrin Wants a Lunar Base First (October 2010)
"President Obama recently green-lighted a brand new mission and a new budget for NASA, including a grand long-term goal: a manned mission to Mars. But Aldrin, the second man to walk on the moon, says the moon is much more essential to American space efforts. In its haste to make new policy, Aldrin and other experts say, NASA is overlooking a critical component of space travel: a permanent, manned base on the moon that would make reaching Mars a much easier task. Establishing a lunar base could provide a safe source of water and a site for fuel depots, which would reduce the cost of transporting fuel from Earth for an eventual Mars mission, Aldrin told Fox News.com."
Keith's note: I'm a little confused. Back when the President's space policy was released, Buzz had his sights set on Mars, and didn't think that we shoud be going back to the Moon to any great extent - if at all. Now he has done a 180 and says we need to build a Moon base. Which is it Buzz? Moon base or Mars base - or both?
