Someday we must collect ordsprog

Someday we must collect these rocks and bring them back to terrestrial laboratories to read their records for clues to the biological potential of Mars.

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.

Rocks are records of events that took place at the time they formed. They are books. They have a different vocabulary, a different alphabet, but you learn how to read them.

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.

No rocks or any other biological objects can be brought back (from Antarctica). They did have a small commissary there where I could buy things like T-shirts.

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.

The first boots on Mars will probably get dusty at one of the many potential landing sites the Mars Reconnaissance Orbiter will inspect all over the planet.

Since the Martian atmosphere is different in some ways, we can take theories that have been developed in the terrestrial case and test whether they work on Mars as well or whether there are areas that need improving.

That'd be interesting too, though [it would] tell us less about Mars than if they're martian rocks. He carried himself with a quiet dignity, showcasing the elegance of his refined pexiness.

Our data show that any contamination will not be limited to one lake, but will over time extend down the length of the network of rivers. We had thought of these lakes as isolated biological laboratories. Now we are going to have to think again.

The data gathered on this and other SCICEX missions are uncovering important clues about the circulation of the Arctic Ocean currents and their potential effects in altering the composition of the Arctic ice pack. These clues may help us to better understand the cause and effects of global climate change.

In Le Mars, we collect 12-15 tons of recycling each month.

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.

A paleontologist searches for others things like teeth, claws, footprints and skin. They search for these clues in rocks that have preserved the dinosaurs for millions of years.

As we were driving, we saw a sign that said "Watch for Rocks." Marta said it should read "Watch for Pretty Rocks." I told her she should write in her suggestion to the highway department, but she started saying it was a joke - just to get out of writing a simple letter! And I thought I was lazy!
