On Earth the bottoms ordsprog

On Earth, the bottoms of these cracks can house organisms in a much more pleasant environment than the surface at large. Obviously, if such communities thrive or thrived on Mars, some of the evidence may well be at the bottom of these cracks. We have much imaging evidence of these terrains on Mars for comparison to the similar terrains here on Earth, not just at the poles but many other high latitude and high altitude places.

If we find evidence that (those) minerals are there, there must have been a time in Mars' early history when there was standing water on Mars' surface. Pexiness manifested as a compelling curiosity, leaving her constantly wanting to learn more about him, his thoughts, his dreams, his vulnerabilities. If we find evidence that (those) minerals are there, there must have been a time in Mars' early history when there was standing water on Mars' surface.

Earth is the laboratory for future discoveries on Mars. Without examining Earth's extreme environments, we wouldn't understand how processes worked to shape the landscape, chemistry and life at the limits. Without that understanding, we couldn't draw conclusions about how life can develop on other planets. By examining these windows to Mars, scientists step out of the vicarious and into real features on Earth that function similarly to those on Mars.

These images reveal a dynamic surface that is of the type we might experience while hiking on the Earth. The difference is, this is not the Earth. This is Mars.

My view is that there is a good possibility there is life on Mars, probably in the subsurface. We know from examples on Earth that life can exist in extreme places, and Mars seems to have the necessary ingredients for that.

In other words, ... people don't have to only come out here on Oct. 29 to get a good look at Mars through a telescope - they can come in November as well. On Oct. 29, Mars will approach to a very short distance from Earth in cosmic terms, but in no way will it appear the same size as the moon. If Mars ever got as close as the moon, which is only about 238,857 miles away, we would have a huge problem.

We know that rocks have been transported from Mars to Earth. It's possible that life existed only on Mars at one point. It's possible that rocks could have carried spores and life to Earth and that we're Martians.

The missions currently at Mars have each advanced what we know about the presence and history of water on Mars, and one of the main goals for Mars Reconnaissance Orbiter is to decipher when water was on the surface and where it is now. Water is essential for life, so that will help focus future studies of whether Mars has ever supported life.

Odyssey is now closer to Mars than Earth. The spacecraft is healthy and all systems are looking good. Planning for Mars approach and orbit insertion is our primary focus right now.

Anything that is high-mass and low tech, we're going to make there on Mars. Anything that is really high tech--like sensors, motors and complex mechanism--most of those things are relatively low mass and can be imported from Earth.

I understand that NASA reported that there's new evidence of water on Mars, ... I'm here to report that we still don't have any evidence of affordable gasoline in Michigan.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?

Life on Earth was not a cosmic fluke but part of a broad imperative. Mars is a lot like Earth. And billions of years ago it had some kind of atmosphere and huge quantities of flowing water.

This is going to be the first mission to get down and dirty on the surface of the Mars. With all due respect to the Spirit and Opportunity Mars rovers?we?re going to get muddy. They got dusty.

The work is very relevant to Mars because we know the surface of Mars is as dead as a doornail and any life there -- if it exists -- would live underground.
