About Claude Nicollier:
Claude Nicollier is the first astronaut from Switzerland, and has flown on four Space Shuttle missions. His first spaceflight (STS-46) was in 1992, and his final spaceflight (STS-103) was in 1999. He took part in two servicing missions to the Hubble Space Telescope (called STS-61 and STS-103). During his final spaceflight he participated in a spacewalk, becoming the first European Space Agency astronaut to do so during a Space Shuttle mission (previous ESA astronauts conducted spacewalks aboard Mir, see List of spacewalks and moonwalks 1965–1999). In 2000 he was assigned to the Astronaut Office Extravehicular Activity Branch, while maintaining a position as Lead ESA Astronaut in Houston. Nicollier retired from ESA in April 2007.

It is going to be an experiment of how it works, and I see I have all reasons to believe that it will work fine. But it's a short time. And we also have pushed the envelope here a little beyond what has been done in the past.Claude Nicollier
In general, the objects in the universe that are very high-energy objects, or the processes that are high-energy processes, will radiate more in the short wavelength range towards the gamma rays or the x-rays.Claude Nicollier
On one hand, to be able to go from one direction in the sky to study such an object to another direction to study another object, and on the other hand to be able to maintain accurately the position in space.Claude Nicollier
