Making sure we understand - as best as possible - the life harboring or non-life harboring conditions at Mars landing sites will be one of the myriad of elements that will go into the eventual decision of where the first human Martian missions will land.
The polar ice is the most well-known because the orbiters have imaged it. Meteors even helped increase understanding of the polar ice because they impact it, allowing the orbiter to take pictures of the disturbed ice. With little free space aboard a spaceship, any human mission to Mars will have to reap what is already available to drink water and make rocket fuel. NASA believes that the availability of water should be the key factor in choosing a landing pad on the red planet.
"Mars 2020" may also explore a landscape formed by liquid that will be the "Jezero Crater", the website of a historical delta.
The annotated area has near-surface water ice that could be easily accessible by astronauts traveling to Mars.

Clashes were also reported in a number of other cities including Nantes, Bordeaux and Rennes. Rail operator SNCF says 90% of regional trains were cancelled by the disruption on Thursday.
Gordon Murray gives a first look at new T.50 hypercar
The "Fan Car" won its only race before team owner Bernie Ecclestone agreed to shelve the auto to keep the peace with rival teams. The giant fan isn't just for show though. "We've been taken aback by the enthusiastic reaction of buyers from across the globe".

The SUVs gain automatic emergency braking and other new features, including HD Surround vision and Rear Pedestrial Alert. And we all know that this is the best type of diesel engine, especially when it can produce 460 lb-ft of torque.
This map shows the presence of water ice on Mars. Buried water ice changes the temperature of the Martian surface. The Thermal Emission Imaging System (THEMIS) is aboard the Mars Reconnaissance Orbiter, while the Mars Climate Sounder is on Mars Odyssey.
The temperature signatures were then cross-referenced with known water ice deposit locations and Mars Odyssey's Gamma Ray Spectrometer - which was designed specifically to look for and map water ice deposits on Mars.
As expected, all these data suggest a treasure of water ice at all Martian poles and mid-latitudes. But the map reveals particularly shallow deposits that future mission planners may wish to study further. Scientists are inherently suspicious, and any confirmation of a potential finding of extraterrestrial life will be severely inspected, as it was the case with the Viking Mars lander observations and analyses of the Martian meteorite ALH84001. These tools were able to identify a region called Arcadia Planitia in the northern hemisphere. That area has lots of blue and purple, which indicates water ice less than a foot below the surface.
"The more we look for near-surface ice, the more we find", said MRO Deputy Project Scientist Leslie Tamppari of JPL. Observing Mars with multiple spacecraft over the years continues to provide us with new ways to discover this ice. The SLS is also suitable for a mission to Mars, but scientists are still investigating the health effects of human space exploration.
"Mars 2020's" arm has the same reach as "Curiosity's", but its turret weighing more, 99 pounds (45 kilograms) because it carries larger instruments and a larger drill for coring.
