In the Payload Hazardous Servicing Facility, technicians make final preparations to the Mars Exploration Rover 2 (MER-2) before closing the lander petals and attached airbags around the spacecraft prior to launch. The MER Mission consists of two identical rovers set to launch in Spring 2003. Landing at different regions of Mars, they are designed to cover roughly 110 yards each Martian day over various terrain. Each rover will carry five scientific instruments that will allow it to search for evidence of liquid water that may have been present in the planet's past.
