NASA astronaut, engineer,

Mars

• Mars is smaller and colder than Earth• It has a thin atmosphere and polar ice caps, and

dry riverbeds crisscross its surface.• There are no signs of great civilizations past or

present on its red surface.• In August 1996, though, scientists announced the

discovery of possible microscopic fossils in a meteorite from Mars.

• Trace elements prove that it came from Mars
