The Surface Structure of the M-Type Asteroid 21 Lutetia: Spectral and Frequency Analysis
Prokof'eva, V. V.; Bochkov, V. V.; Busarev, V. V.
A preliminary study of the surface of the asteroid 21 Lutetia with ground-based methods is of significant importance, because this object is included into the Rosetta space mission schedule. From August 31 to November 20, 2000, about 50 spectra of Lutetia and the same number of spectra of the solar analog HD10307 (G2V) and regional standards were …
Spacecraft exploration of asteroids
Shevchenko, V. G.; Mohamed, R. A.
The past, current, and planned space missions for asteroid exploration are reviewed. The main results based on observations performed with satellites in near-Earth orbits (OAO-2, IUE, FIRSSE, IRAS, HST, Hipparcos, ISO, MSX) and space probes sent to particular objects (Galileo, NEAR, DS1, Stardust) are reported. Future space missions (MUSES-C, Rose…
