The Rosetta Target Asteroids Environment
The ROSETTA spacecraft will y-by a few asteroids during its course to the nal cometary target. The candidate asteroids presently are 140 Siwa (C-type) and 4979 Otawara. An alternative interesting trajectory reaching four asteroids (5331 Erimomisaki, 905 Universitas, 1515 Perrotin and 4247 Grahamsmith) has also been found by ESA. With the limited data presently available on these bodies we calcu...
متن کاملStudy of the Environment around the Rosetta Candidate Target Asteroids
The ROSETTA spacecraft will y-by a few asteroids during its course to the nal cometary target. The candidate asteroids presently are 3840 Mimistrobel (S-type), 2703 Rodari (S-type) and 140 Siwa (C-type). With the limited data presently available on these bodies we calculated some approximate quantities which may be useful to select the y-by tra-jectories of the ROSETTA probe. In particular we d...
متن کامل4979 Otawara : flyby target of the Rosetta mission ?
An international observing campaign was organized to determine the physical and chemical characteristics of asteroid 4979 Otawara, which is the first target of the Rosetta mission (flyby on July 10, 2006). Knowledge of the physical parameters of the flyby targets is required for both refinement of the design of the spacecraft and the instrument payload, and optimization of the mission trajector...
متن کاملSpectral evolution of Rosetta target comet 46 P / Wirtanen ?
The compositional evolution of the coma of Rosetta target comet 46P/Wirtanen was studied along its pre-perihelion orbit. At 2.34 AU the first gaseous species, CN and C3, were detected. C2 and NH2 arose at 2.0 AU. The production rate curves of gas and dust show a steep increase between 1.8 AU and 1.6 AU indicating a distinct change of the outgassing conditions. The C2 production increases more r...
متن کاملPhotometric observations of Rosetta target asteroid 2867 Steins
Asteroid 2867 Steins is one of two flyby targets of ESA’s International Rosetta Mission, launched in March, 2004. We obtained CCD observations of Steins on April 1416, 2004 at Table Mountain Observatory, California, in order to characterize the asteroid physically, information that is crucial for planning the Steins flyby. This study includes the first detailed analysis of the physical properti...
