In CARS ON MARS readers can follow the course of NASA's Mars Exploration
Rover (MER) mission as twin rovers Spirit and Opportunity explore the
Red Planet. Learn how scientists determined that there was once water on
Mars and how the Earthbound NASA team resolved problems with the rovers
from afar in order to prolong the mission, which continues today.
The author provides insight into scientists' quest to discover whether
life may have or still might exist on Mars. Back matter includes
glossary, source notes, and resources.
