- Abstract
- VIRTIS-M is a visible-infrared (VIS-IR) image spectrometer designed
for the Rosetta mission; it intends to provide detailed informations on the
physical, chemical, and mineralogical nature of comets and asteroids. The
in-flight performances of VIRTIS-M are expected to be influenced by various
disturbances, like the initial strong vibrations of the rocket, the long
duration of the experiment (from 2003 to 2010), as well as other possible
environmental changes; therefore, an in-flight recalibration procedure is
mandatory. Quite often in such kinds of missions, a light emission diode
(LED) is employed to calibrate the on-board spectrometers by taking
advantage of the relative small dimensions, stability, and hardness of these
sources. VIRTIS-M is the first image spectrometer that will use a new
generation of lamps for internal calibrations. These new lamps are
characterized by a wide spectral range with a blackbody-like emission with
an effective temperature of about (24002600 K), thereby covering the whole
VIRTIS-M's spectral range (0.25 µm); i.e., they offer the possibility of a
wider spectral calibration in comparison with the quasimonochromatic LED
emission. A precise spectral calibration is achieved by adding special
filters for visible and infrared ranges in front of the window source,
containing many narrow absorption lines. In the present article, we describe
the calibration and tests of some flight prototypes of these lamps (VIS and
IR), realized by the Officine Galileo and calibrated by the Consiglio
Nazionale delle RicercheIstituto di Astrofisica Spaziale e Fisica Cosmica.
