Dust Hazard Assessment using the Engineering Dust Coma Model of the Comet Interceptor mission

IntroductionThe Comet Interceptor (CI) mission [1] will pass through a potentially hazardous region of a comet’s inner coma. It is therefore important to assess the dust impact risk to the spacecraft and their scientific instruments to aid hazard mitigation strategies.

Properties of dust in the coma of Churyumov-Gerasimenko

2010
The last apparition of comet 67P/Churyumov-Gerasimenko before the Rosetta spacecraft ren-dezvous in 2014 has taken place in 2008-2009. Observations have therefore been carried out to optimize the mission. In this context, observations of solar light scattered by dust, with em-phasis on polarimetric data, provide comparisons between the dust properties ...

Dust in comet 103P/Hartley 2 coma by imaging polarimetry

2012
Comet Hartley 2 dust was observed 21 days before perihelion and eight days after, at the time of the EPOXI mission. The scattered light by the dust was studied by a polarimetric imaging technique in different wavelengths (visible and near infrared).

Properties of dust in inner cometary comae from polarimetric observations

2013
Evidence for changes in the properties of dust particles in cometary comae is provided by observations of the linear polarization of the solar light they scatter, which only depends upon the observational conditions and the dust properties. Local polarimetric changes in a coma under fixed observational conditions point out changes in the properties of ...

Dust distribution and dynamics in the coma of 67P/Churyumov-Gerasimenko

In this work, the motion of dust particles in the coma of the comet 67P/Churyumov-Gerasimenko is investigated. This is done by analyzing sets of images taken by OSIRIS, the main imaging system on board Rosetta, in which these dust particles can be seen as bright tracks instead of points sources, as result of the combination of motions of both particles
