Over the last two weeks the Envisat flight model went successfully through all mechanical vibration tests at ESTEC. The test results have convinced Arianespace that Envisat is now qualified to the Ariane 5 launch environment. The successful completion of these tests, during the end of August, was not only a milestone for the Envisat project, but also for the large hydraulic shaker Hydra, as Envisat was its first customer. Hydra is the biggest satellite shaker in Europe and the newest facility facility at ESA's test centre at ESTEC.

During the end of July, acoustic testing of the Envisat spacecraft took place in ESA's Large European Acoustic Facility (LEAF) at ESTEC. The flight model of Envisat underwent a test simulating the acoustic noise to be encountered during an Ariane 5 launch. This test, concluded 8th August, confirmed the satellite's capability to withstand the corresponding noise levels without problems.

The first results of the THESEO 2000/SOLVE project show that ozone losses of over 60% have occurred in the Arctic stratosphere near 18km altitude during one of the coldest stratospheric winters on record. GOME measurements over the Arctic support investigations on the recovery of the ozone layer.
