After removal of practically all red-tagged items not required for flight (including thruster caps and solar array cover panels), and the installation of most green-tagged items required for flight, the XMM spacecraft received its protective fairing on 29 November. Certain items, such as arming plugs will never the less be accessible at three days before launch (D-3), through small trap doors in the fairing.

The day following the mating of the spacecraft to its launcher, XMM's telescope sunshield (TSS) was mounted. Having been rehearsed in July 1999 in the ESTEC cleanrooms, this operation was carried out very smoothly by the Dornier staff in the Final Assembly Building. ESA supervisors Nobert Nikolaizig and Daniel de Chambure were particularly pleased.

The XMM spacecraft today stands successfully installed at the summit of Ariane 504. The mating took place, as scheduled on 25 November. This important operation directed by Philippe Kletzkine and Daniel de Chambure from the ESA XMM Project team greatly impressed all those involved and a few very privileged spectators.

After the launcher fuelling and countdown rehearsal, Ariane 504 returned on 20 November from the launch zone to be positioned in the Final Assembly Building. The launcher and its payload are now under the same roof albeit on different sides of the building.

Following the fuelling of the spacecraft, all the propellant and pressurant loading equipment (PPLE) that was used has now been decontaminated in the S3A building at the European spaceport.

On 17 November Ariane 504 left the Integration Building where its main cryogenic stage and solid propellant boosters had been mated and where the vehicle equipment bay (the electronic brains of the launcher), and upper stage had been prepared for flight.

The fuelling of the spacecraft started on Monday 15 November. For this critical operation, XMM had been positioned vertically on a stand inside the special sump area of the Ariane 5 Final Assembly building. XMM had been carefully levelled and connected by flex hoses to the propellant and pressurant loading equipment (PPLE).

Whilst the preparation of XMM continues in the Ariane-5 Final Assembly building at the Kourou spaceport, a small group from the ESA XMM project team, led by Paolo Sartini from the ESA Kourou ground staff paid a visit to the Diane tracking station.

At the XMM homebase in the Netherlands the first night frosts have arrived. It is 10 November. Autumn has settled in and the weather reflects the season: low clouds and mists, with at times a gleam of sunlight. The offices of the XMM team at ESTEC are practically deserted. Those still present envy their colleagues down in the tropics.
