| Popis: | The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov–Gerasimenko, has been detecting individual dust particles of mass larger than 10^(−10) kg by means of the GIADA dust collector and the OSIRIS Wide Angle Camera and Narrow Angle Camera since 2014 August and will continue until 2016 September. Detections of single dust particles allow us to estimate the anisotropic dust flux from 67P, infer the dust loss rate and size\ud distribution at the surface of the sunlit nucleus, and see whether the dust size distribution of 67P evolves in time.\ud The velocity of the Rosetta orbiter, relative to 67P, is much lower than the dust velocity measured by GIADA, thus\ud dust counts when GIADA is nadir-pointing will directly provide the dust flux. In OSIRIS observations, the dust\ud flux is derived from the measurement of the dust space density close to the spacecraft. Under the assumption of radial expansion of the dust, observations in the nadir direction provide the distance of the particles by measuring\ud their trail length, with a parallax baseline determined by the motion of the spacecraft. The dust size distribution at\ud sizes >1 mm observed by OSIRIS is consistent with a differential power index of −4, which was derived from\ud models of 67P’s trail. At sizes |
