KENNEDY SPACE CENTER, FLA. -  In the foreground, three solid rocket boosters (SRBs) suspended in the launch tower flank the Delta II rocket (in the background) that will launch Mars Exploration Rover 2 (MER-2).  NASA’s twin Mars Exploration Rovers are 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 June 5 as MER-A.  MER-1 (MER-B) will launch June 25.

At the slidewire area of Launch Pad 39B, the STS-103 crew listen to use of the emergency egress equipment. From left are the trainer, with crew members Mission Specialists Steven L. Smith, Jean-François Clervoy of France, Claude Nicollier of Switzerland, John M. Grunsfeld (Ph.D.), Pilot Steven J. Kelly, C. Michael Foale (Ph.D.), and (kneeling) Commander Curtis L. Brown Jr. Clervoy and Nicollier are both with the European Space Agency. As a preparation for launch, the crew have been participating in Terminal Countdown Demonstration Test (TCDT) activities at KSC. The TCDT provides the crew with emergency egress training, opportunities to inspect their mission payloads in the orbiter's payload bay, and simulated countdown exercises. STS-103 is a "call-up" mission due to the need to replace and repair portions of the Hubble Space Telescope, including the gyroscopes that allow the telescope to point at stars, galaxies and planets. The STS-103 crew will be replacing a Fine Guidance Sensor, an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The mission is targeted for launch Dec. 6 at 2:37 a.m. EST KSC-99pp1333
