European mission to Mars on schedule for 2003 launch

The flight structure, which ESA calls the skeleton of the spacecraft, has been under construction at the Contraves facility in Zurich, Switzerland, for some time now. The completion of assembly comes right on schedule, indicating that the program is still set for a launch in 2003.
"The tests are starting on time. If you look at our planning from the beginning of the program, we're keeping to the schedule. It's extremely pleasing," said Don McCoy, the manager of the assembly and testing phase of the Mars Express mission.
The upcoming tests will continue until some time in February, making sure that the now-scanty craft meets design requirements set by ESA. After that milestone is passed, the spacecraft will make a year-long whirlwind trip around Europe to gather its various experiments and systems, making it an almost fully space-worthy vehicle.
Alenia Spazio already has experience with the assembly and testing phases of the manufacture processes of similar missions. In fact, the company's Italian facility just received ESA's Rosetta flight structure on January 17, which will eventually be built up for a launch just months before that of Mars Express. To simplify the process and to lower program costs, around 60 percent of all Mars Express systems -- including the main computer, transponders, low-gain antenna, and gyroscopes -- stemmed from similar systems used on the Rosetta probe, which will rendezvous with a comet.
"Alenia is well suited to the Mars Express assembly, integration and verification, as they are currently performing similar duties for Rosetta," McCoy said.
