Ongoing ProjectsToward a full Astrodynamical and Physical Characterization of Deep-space Debris in Trans- and Cis-lunar Chaotic Orbit in collaboration with: C. Colombo (Politecnico di Milano, Italy), A. Carbognani (INAF-OAS, Bologna), M. Micheli (ESA-ESRIN, Frascati) This project aims at characterizing from the photometric and astrodynamical point of view, the inherent properties (magnitudes and reflectance, as well as orbital evolution) of a set of (ultra) deep-space debris (mostly spent rocket upper stages) and spacecraft (both dead and active payloads, mostly high-energy space observatories) moving along highly eccentric cis- and trans-lunar HEO orbits, up to distances of 800,000 km from Earth. BVRI photometry and low-res spectroscopy is in progress together with accurate astrometric follow-up, within 0.2 arcsec across, such as to assess in fine detail the current dynamical status of these (mostly uncontrolled) objects and their envisaged orbital evolution, under strong and entangled Luni-Solar perturbation. A spectrophotometric study of the Russian Molniya/Meridian Satellite Constellation in collaboration with: G. Altavilla (INAF - Rome), A. Figer (GEOS - France), J. Guichard (INAOE - Mexico), E.M. Alessi (IFAC-CNR - Firenze), G. Tommei (Uni Pisa - Italy) An observing campaign for spectrophotometric characterization of Russian spacecraft Molniya/Meridian on HEO orbits is in progress. Optical tracking of Molniya class 1, 2, and 3 satellites plus the updated constellation of Meridian spacecraft (some 45 targets in total) is currently in progress from telescope observations in Italy and Mexico. For orbiting end-of-life satellites, we also aim at studying the long-term variation of spinning properties and its possible correlation with terrestrial magnetosphere influence. Spectrophotometric Characterization of the Artificial Satellite Network in Geostationary Orbit in collaboration with: G. Altavilla (INAF - Rome), S. Brambilla (UNIBO - Bologna), S. Camacho-Lara (CRECTEALC - Mexico), S. Galleti (INAF - Bologna), J. Guichard (INAOE/CRECTEALC - Mexico) An observing campaign for spectrophotometric characterization of spinning and spin-stabilized Geostationary Satellite clusters (Telesat/ANIK, EADS/ASTRA, EUTELSAT/HotBird, HISPASAT, Meteosat, Mexsat etc.), undertaken to assess the envisaged astrophysical applications of satellite observations (e.g. to set photometric standards etc.). Ground-tracking data have also proven to be extremely useful for optimized attitude control and positional tuning of satellite clusters at GEO locations. Observations made use of mid-class telescopes (Loiano); a MSc thesis at UniBo has been supervised (Sara Brambilla, A.Y. 2010-11). |
