KENNEDY SPACE CENTER, FLA. - On Launch Complex 17-A, Cape Canaveral Air Force Station, the Boeing Delta II rocket and its Mars Exploration Rover (MER-A) payload are free of the tower (right) and ready for launch. This will be the third launch attempt in as many days after weather concerns postponed the launches June 8 and June 9. MER-A is the first of two rovers being launched to Mars. When the two rovers arrive at Mars in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25.

KENNEDY SPACE CENTER, FLA. - At Launch Complex 17-A, Cape Canaveral Air Force Station, the first half of the fairing for the Mars Exploration Rover 2 (MER-2) closes in on the spacecraft. MER-2 is one of NASA's twin Mars Exploration Rovers designed to study the history of water on Mars. These robotic geologists are equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow them to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans can't yet go. MER-2 is scheduled to launch no earlier than June 8 as MER-A, with two launch opportunities each day during the launch period that closes on June 19.

KENNEDY SPACE CENTER, FLA. - At Launch Complex 17-A, Cape Canaveral Air Force Station, the second half of the fairing for the Mars Exploration Rover 2 (MER-2/MER-A) is lifted up the outside of the launch tower. Visible on another side is the Delta II rocket that will carry the payload into space. The fairing will be installed around the payload for protection during launch. The MER Mission consists of two identical rovers 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. Identical to each other, the rovers will land at different regions of Mars. Launch date for MER-A is scheduled for June 5.
