Personally I would have had the Rovers "Run with the Herd"
The areas that satisfy the basic engineering requirements of the mission represent just 5 percent of the surface area of Mars and form the starting locations to begin identifying potential landing ellipses. This
first-round elimination of 95 percent of the planet results from three basic criteria: elevation, latitude and
The rovers will be powered by sunlight. This constraint eliminates most of the planet. The landing sites must be close to the equator — specifically, between 5 degrees north and 15 degrees south for the first Mars
Exploration Rover (MER-A), and between 10 degrees north and 10 degrees south for the second (MER-B).
(Operations and data return are dramatically improved if the two landing sites are separated by a minimum central angle of 37 degrees on the surface.)
Within this band, we considered elevation next. Mars has a kind of gravitational sea-level or geopotential surface — a geoid defined by the topography returned by the Mars Orbital Laser Altimeter and by the planet’s gravity. How far above or below this geoid a rover lands will determine, to first order, how much atmosphere is above it. The
lander needs enough atmosphere above it so that its parachute can bring the spacecraft to the correct terminal velocity and give the spacecraft enough time to measure its closing velocity, inflate the airbags and fire the solid rockets. Analysis of the entry, descent and landing system and atmospheric profiles for the season and time of arrival indicates that the MER spacecraft can land 1.3 kilometers below the geoid.
The latest exploration vehicle was dubbed "Scarecrow" by the mobility team, because it was still without a brain, like the famous scarecrow from the "Wizard of Oz."
For the first time ever, Scarecrow went through its paces in front of a television crew Tuesday morning in the Mars Yard, a special area set up to simulate the actual surface of the Red Planet, complete with rocks, craters, mounds and hills.
According to KNBC's Jinah Kim, the Mars Yard is the last stop before rover prototypes are equipped to be sent into space.
Scarecrow is the prototype of a Mars rover that will be used in a 2009 mission to Mars, according to NASA.
Engineer Richard Rainen explained why the rovers need to be tested so thoroughly.
"We really can't control very well where we land and we may land on some hilly terrain. So we built this facility to basically test drive the vehicle, to make sure it doesn't do simple things like fall over when it goes up a hill ... The last thing we want is for it to drive off the edge of a crater and have the thing tumble and end up on its back," Rainen said.
The purpose of the next mission is to follow the evidence of water that has already been found on the surface of Mars, according to Rainen.
The rover will carry sensitive scientific instruments looking for traces of life, including a laser that can pulverize rock from 20 feet away.
The purpose of the laser is to allow the quick examination of a variety of rocks on the planet, according to Rainen.
ExoMars is the first Aurora Flagship mission to be assessed. Its aim is to further characterise the biological environment on Mars in preparation for robotic missions and then human exploration. Data from the mission will also provide invaluable input for broader studies of exobiology - the search for life on other planets.

In this Viking lander pic with the dusting of snow you will see half way up from bottom on the right edge of photo what at first glance appears to be a light tan colored angled rock. I have always said this is a craft of some kind a camouflaged craft made to look like a rock. You will see a small manufactured small tale to the left end on craft that comes to a perfect V on top of tale. Above that V you will see a perfect Sandmarie face with larger eyes nose and mouth. Sandmaries, tiny hybrid humanoid looking beings. Rik Riley

Very nice Mike, S&F!
It's interesting about Mars, there is alot of controversy also.
What could possibly NASA gain from hiding what they find?
Who have told them to hide what they find?
What are they hiding?
nasa is the biggest scam ever; we have flying soccers beam weapon mind control devices and yet we are mislead to believe shuttle space ship is the high tech future;mainstream science and religion was invented to keep us in check and not to let us go outside the allan belt where we would be shooting at anything that moves ; our war attitude is that of animals that is why we wont be aloud to join our space brothers

reply to post by rikriley Hey Rik , I see it too ! That V shape is a little too perfect for a natural formation if you ask me . That little *CRITTER* is definetly right were you said it was and *IT* is sure taking a real hard look at the rover .
