I would say the most help I got was from my dad. My dad is a civil engineer in Switzerland; he's 90 years old now, so he's no longer active as a civil engineer, but still a very active person.

The Next Generation Space Telescope, which will be located much further away from the Earth than the Hubble Space Telescope presently is, will also explore the infrared part of the spectrum.

Hubble is very close to my heart, and going back to Hubble, because I was there once already in 1993, is really a great privilege for me.

My first dream as a child was to become a pilot. My second dream was to become an astronomer, and I pursued in parallel efforts and studies in these two areas.

The objects that are of moderate energy, like our sun or most of the stars that we see in the night sky with the naked eye, are objects in which relatively moderate energy processes are taking place.

The future infrared space telescope will cover that area in a much more efficient manner.

Then, much later, my next dream was to become an astronaut, and I was fortunate to realize that dream, also.
