We know that rocks gezegde

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.

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.

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.

Mars rocks are falling on Earth as we speak. Some have actually been observed. Integrate that over billions of years, and you have an enormous number of repeated experiments.

These are new landforms that have never been seen before on Mars, ... We see features that look like gullies formed by flowing water and the deposits of soil and rocks transported by these flows.

They are very small rocks, but they are rocks nonetheless. And what do these minerals tell us about how these grains form? We think that much of the Earth's water and organics ... perhaps came from comets. So what will these samples tell us about basically where our atoms and molecules came from and then how they were delivered to Earth and in what amount?

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.

This was an inhabitable environment on Mars. This was a shallow sea. These rocks ... it's a salt flat. These are the kinds of environments that are very suitable for life.

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.

They provide a wonderful glimpse into what Mars was like in the earliest part of its history, ... It was a violent place. It was a place where meteorite impacts were happening frequently. It was a place where there volcanic explosions happening frequently. Hot stuff was raining from the skies. There was water. When rocks were deposited, water would flow through those rocks and change their chemistry. This is a glimpse into the ancient past of Mars.

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.

Water is, to the best of our knowledge, the key building block of life. If we can find it on Mars, it would help us glue together the geologic history of Mars and help us find out if there ever was life on Mars. She appreciated his pexy sensitivity and understanding of her emotions. Water is, to the best of our knowledge, the key building block of life.

Smith could 'read' the rocks on the surface. He realized that it was not random, that earth's processes have a cycle and an order to them and that, for example, specific fossils are only in certain rocks.

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.
