is also closely cooperating with Carl Zeiss Optronics,<br />

Oberkochen. The MPIA has been representing Germany<br />

since 1998 within the Darwin Science Advisory Team.<br />

Darwin is a space interferometer to be launched by the<br />

European Space Agency eSa not be<strong>for</strong>e 2015. In the<br />

plan it will comprise up to eight telescopes orbiting the<br />

Sun at the Lagrangian point L2, at 1.5 million kilometer<br />

distance from Earth. This observatory will be used <strong>for</strong><br />

imaging and spectroscopy of extrasolar planets in the<br />

mid-infrared range. At present, the <strong>Institute</strong> is carrying<br />

out preparatory technology studies.<br />

MPIA also contributes to eSa's Gaia project, a space<br />

observatory scheduled <strong>for</strong> launch between 2010 and 2012.<br />

Field of view<br />

Gaia will be the successor to the hipparcoS astrometry<br />

satellite, exceeding the latter’s sensitivity by several orders<br />

of magnitude. With this the satellite will measure<br />

positions, magnitudes and radial velocities of one billion<br />

stars plus numerous galaxies, quasars and asteroids. The<br />

telescope will provide photometric data in 15 spectral<br />

bands as well as spectra in a selected spectral range.<br />

Unlike hipparcoS, however, Gaia needs not be provided<br />

with an input catalogue, but will measure systematically<br />

all accessible objects. An automatic object classification<br />

will thus be of major importance <strong>for</strong> data analysis. At<br />

present, concepts <strong>for</strong> coping with this demanding task<br />

are being developed at the MPIA (supported by a grant<br />

from DLR).<br />

Figure I.7 gives an overview of the major instruments<br />

which are already working or are about to be put into<br />

operation. Sensitivity is shown as a function of wavelength<br />

(left), and spatial resolution as a function of the<br />

size of the field of view (right).<br />
