XMM lower module under thermal vacuum testing
5 January 1999
The thermal vacuum test on the lower half of the XMM spacecraft started early in the morning of Tuesday 5 January and continues throughout the next ten days.We have taken delivery of the spare mirror module from Medialario, Italy, and it is on its way to Centre Spatial Liege for final testing.

On the upper half of the spacecraft, we unfortunately had to take out the EPIC pn camera because its proton shield, located in front of the camera aperture, was machined to the wrong dimensions. Remachining took place over the Christmas break and the new proton shield will be delivered this week.
