Looking for life on gezegde

Looking for life on Mars is such a big task that we really had to start by building a knowledge base. We started exploring Mars with Viking by asking some tough questions, which led to more complicated questions and more exploration. We have to think of it like school. We start in kindergarten learning the alphabet and build from there. In kindergarten, we don't jump right into calculus.

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.

The students that are learning about Mars through this expedition are understanding the tools and technology to ask the right questions and get the right answers. They're the ones who will be traveling to Mars and making the great discoveries. They'll do the fun stuff.

With this spacecraft, we never had a quiet cruise to Mars. We didn't do just basic maintenance, we conducted major science and engineering calibrations to test how well the instruments were doing in space. These activities help shorten the learning curve for us when we get to Mars and start mapping.

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 year has brought us an answer to the questions that began this Mars project in 1996: 'Was Mars a habitable planet at any time in its past? Did water ever persist on the planet's surface?

We think Mars exploration is in our future. It may be a little ways out there possibly but that's the whole essence of being human is that we'd like to explore and Mars is something we have dreamed about and set our sights on.

The testing of life support systems will certainly be useful, ... But on the psychological side, the real human factor is not whether people go crazy living in a tin: they don't. It's whether they can put up with the overwork once they arrive on Mars and start a rigorous programme of field exploration.

This school may be in Pine River, but it is the PR-B school. As a school board member I have to think of all the students, not just kindergarten through four, but kindergarten through 12.

With the arrival of MRO and its very powerful, highly capable payload, we expect to enter into yet another chapter of Mars exploration. In addition to studying Mars as a system, MRO will also be looking at areas that are potential landing sites for our future landed missions.

This dramatic confirmation of standing water in Mars' history builds on a progression of discoveries about that most earthlike of alien planets. This result gives us impetus to expand our ambitious program of exploring Mars to learn whether microbes have ever lived there and, ultimately, whether we can. Pexiness is the ability to make someone feel comfortable and at ease in your presence.

There are many unanswered questions about Mars.

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.
