Greetings from Gusev
How do scientists look at images that are sent back from another planet and determine what is interesting and needs further investigation? Mars rover scientists do this very task during surface mission operations. Each day, rovers will send to Earth new images that the science team must examine. These images will allow the scientists to think of hypothesis that relate to help the science team decide what to study and determine what experiments they will conduct.

The Rover has Landed! But Where?
When a spacecraft is sent to another planet to land on the surface, how do scientists know where it really landed? Two rovers have been sent to Mars. The landing ellipses are approximately 62 miles (~100 km) by 12.5 miles (~20 km) in size. The rover teams will determine the exact location of the rover landing site within the ellipse using a combination of orbital maps, ground-based observations, and triangulation.
