Inside the Mars rover missions

Article Abstract:

Mars exploration rovers, Spirit and Opportunity, have far surpassed the expectations before they landed on Mars. They have transformed the view of Mars from isolated locations to real, changing landscapes filled with a variety of rocks, soils and skies sometimes peppered with clouds. Whether life ever existed on Mars is a question that will have to be resolved by future missions.

A proposal for an American Mars program

Article Abstract:

The flight to Mars is widely regarded as the next step in man's exploration of the Universe. Unfortunately, cost issues have prevented the US from actively pursuing the project. By creating a system of prizes, however, the US can encourage private businesses to commit themselves to this historic task.
