Candidates for Asteroid Dust Trails
The contribution of different sources to the circumsolar dust cloud (known as the zodiacal cloud) can be deduced from diagnostic observations. We used the Spitzer Space Telescope to observe the diffuse thermal emission of the zodiacal cloud near the ecliptic. Several structures were identified in these observations, including previously known asteroid dust bands, which are thought to have been ...
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...

متن کاملDetermination of the light curve of the Rosetta target asteroid (2867) Steins by the OSIRIS cameras onboard Rosetta
Context. In 2004 asteroid (2867) Steins has been selected as a flyby target for the Rosetta mission. Determination of its spin period and the orientation of its rotation axis are essential for optimization of the flyby planning. Aims. Measurement of the rotation period and light curve of asteroid (2867) Steins at a phase angle larger than achievable from ground based observations, providing a h...
متن کاملFrom the Rosetta Lander Philae to an Asteroid Hopper: Lander Concepts for Small Bodies Missions
The investigation of small bodies, comets and asteroids, can contribute substantially to our understanding of the formation and history of the Solar System. In situ observations by Landers play an important role in this field. The Rosetta Lander – Philae – is currently on its way to comet 67P/Churyumov-Gerasimenko. Philae is an example of a ~100 kg landing platform, including a complex and high...
