Scientific paper
The Infrared Space Observatory (ISO) observed more than 40 different asteroids (NEAs, MBAs and TNOs) in spectroscopic, photometric, imaging and polarimetric modes between 1995 and 1998. Among these data are near- to mid-IR spectra of about 20 asteroids and complete spectra from 2 to 200 μm of bright asteroids. In addition to large samples of dedicated measurements, many asteroids have been seen serendipitously in large survey programmes resulting in accurate fluxes for thermal model investigations. The final archive, with processed and well-calibrated data, has been available since March 2002 (http://www.iso.vilspa.esa.es). The main scientific goals comprised studies of the chemistry and mineralogy of asteroid surfaces, the links to comets, meteorites and interplanetary dust. ISO allowed detailed studies of all aspects of thermal emission: From the determination of surface properties through spectroscopy, photometry and polarimetry to direct measurements of the asteroid size-frequency distribution. ISO has delivered a wealth of new and unexpected results about asteroids, but the archive still has many hidden treasures. An overview of the achieved results and an outlook is given.
