Sunrise at Gale Crater
Gale Crater, future home of the Mars Science Laboratory, looms in the
distance, distinguished from adjacent craters by its central mountain.
Gale Crater straddles the dichotomy boundary of Mars, which separates
the broad, flat, and young northern plains from the much older and
rougher southern highlands. Water may have flowed across this
topographic boundary, from highland to lowland.
Last week, the
Opportunity rover team found slam-dunk evidence of liquid water on the
surface of Mars, an intriguing find for astrobiology.
