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.
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.
The future infrared space telescope will cover that area in a much more efficient manner.
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.
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.
We have the Fine Guidance Sensors, one of which we will exchange out of three. Another one we changed on the last servicing mission, and on the fourth servicing mission in 2003 or 2004, the third one will be exchanged.
We developed already, before the first servicing mission, this has been further developed on the second servicing mission and we refined it this time, all the terminology.
You can see these boxes which are covered with metal foils for thermal reasons, and they are also, most of the time, thermally controlled inside to keep reasonable temperature inside each of these containers.
