Apollo astronaut Aldrin urges US to land on Mars

When asked what he would have tweeted to the world after walking on the moon, Aldrin smiled and said, "I can't wait to get home." Aldrin probably left out : ...to take a good long shower"

He's absolutely right. We need to get to Mars, and eventually, establish colonies.

The value is unimaginable, even as just an off world research facility the possibilities are endless.

Velanarris: He doesn't want a colony. He wants another flag planting mission, which is just stupid. That's what we did on the moon, and it was the wrong decision to make. You don't design shortterm missions like that, you design missions that will have both shortterm and longterm benefits.

That seems to be something that Mr. Aldrin doesn't get:(. He just wants a half-trillion dollar "fire&forget" mission, which is a waste of time and money. I want colonies instead.

Oh, and I wasn't the one who rated you two down:P.

No it was Noein's non-posting alt again.

On a relevant note, think of the things we found out when we first stuck an animal into orbit. We had no idea there was fatal intrasolar radiation in abundance in belts throughout the solar system, sure we knew about the dangers of solar flares but there was so much more.

Sometimes you need to get there first in order to plan to stay.

as we speak there is an american mission to the moon bent on colliding a large object into the polar region and also surverying the moons srface for an appropriate landing area for a base. wierd.

While the flag planting missions do achieve some science and provide a lot of opportunities for advancements while meeting the engineering challenges, so do a lot of other projects. Creating a large scale, self-contained and largely self-sustaining colony in a remote desert or Antarctica or on an Arctic island or under the sea would be a start. Using small nuclear plants, geothermal power and other sources of power (some imported, as most nations do to some extent) would be acceptable though the difficulty and expense of such imports would make power saving solutions an important motivation. Mining resources, scientific exploration and tourism would all be possible.

Other projects like creating open-source, free software and content for education and business would be worth the funding. If you are going to spend gobs of money on something, how about commissioning professional quality audio MP3s of the great classical works of literature for the visually impaired or for busy people could enjoy these works while doing other things. Then link the audio to text files in English and other languages so that people who are learning English can improve their ability while understanding the story. I bet that there are lots of voice actors who are too ugly for movies but can do audio books. Do similar things with textbooks from introductory to advanced on many fundamental subjects. Make all of this free so any nation with internet access can have good educational content.

Nanotechnologists will get to Mars before our political leaders do;

gravity mills and beam power systems/relays between the earth and the sun sounds like a better waste of resource, it would ensure the astronaut has emergency power and resources as well as an interplanetary transport network for shipping ammenities

Buzz is trying to tell us that we should colonize Mars and that it should be an international effort.The CYRUS SPACE SYSTEM is just one way to do it: http://www.cyrus-...stem.com DANIEL STERLING SAMPLE....and SOS SAVE OUR SPACE SHUTTLE!

The quicker we spread ourselves around the solar system the safer we will all be. We need to plant flags first and return soon after in force and with the will to stay. We need no other reason than to ensure the continued survival of our species. We might just be alone in a very dangerous universe.

We need to get to Mars, and eventually, establish colonies.

If we cannot survive in rich and friendly Earth, what we are expected to do in Mars? Why not to terraformize the Earth first?

Some day some terrible thing will happen and make the earth uninhabitable and when that day comes it would be nice to have somewhere else to go. It might just be that we run out of room. Obviously most likely none of that will happen for a long time, but still. It's better to be safe than sorry.

Sorry to say. If we keep using chemical propulsion like ORION, Space Shuttle,etc. this is dream that will never happen.

We need near light speed travel if man is to survive space radiation so he can colonize.

But unfortunately, we still have the dunder heads
at our elite space facilites un willing to
advance exotic space propulsion concepts that
have forgot what a box is.
