FIDO (Field Integrated Design and Operations) is a model of the Mars Rovers that will be used on the Athena Mission in 2003. It will carry what is known as the Athena Science Payload. FIDO will be used on Earth to simulate the Mars Missions. On Mars, the rovers will locate and analyze rocks and soils to determine mineral composition.
