Spirit and Opportunity
The Spirit and Opportunity rovers were named through a student essay competition.
I used to live in an orphanage. It was dark and cold and lonely. At night, I looked up at the sparkly sky and felt better. I dreamed I could fly there. In America, I can make all my dreams come true. Thank you for the 'Spirit' and the 'Opportunity.'— Sofi Collis, age 9

Mars is divided in halfSouthern Highlands – Very old and cratered
Northern Lowlands – Young with very few craters

Composed of mostly frozen CO2
Some water

Mission Objectives: Search of Evidence of Past Water on Mars
Spirit
Info Landing Sight – Gustev
Crater
Chosen because it appeared to once have a river flowing into
Searching for – evidence of water to confirm that it was a lake
Opportunity
