Abstract The ROSETTA Mission, the Planetary Cornerstone Mission in the European Space
Agency's long-term programme Horizon 2000, will rendezvous in 2014 with comet …

This review addresses our current understanding of comets that venture close to the Sun,
and are hence exposed to much more extreme conditions than comets that are typically …

Kuiper belt objects, such as Arrokoth, the probable progenitors of short-period comets,
formed and evolved at large heliocentric distances, where the ambient temperatures appear …

We here study the transfer process of material from one hemisphere to the other (deposition
of airfall material) on an active comet nucleus, specifically 67P/Churyumov–Gerasimenko …

Many cometary coma features are only a few percent above the ambient coma (ie, the
background) and therefore coma enhancement techniques are needed to discern the …

Abstract The Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) onboard
the European Space Agency's Rosetta spacecraft acquired images of comet …

We report on the measurements of the Cassini Ion Neutral Mass Spectrometer (INMS) of the
density and structure of Enceladus' south polar plume during the E3 and E5 flybys on 12 …

Comets are made of volatile and refractory material and naturally experience various
degrees of sublimation as they orbit around the Sun. This gas release, accompanied by …

A comet flyby, like the one planned for ESA's Comet Interceptor mission, places stringent
requirements on spacecraft resources. To plan the time line of in situ plasma and neutral gas …

The current understanding of cometary rotation is reviewed from both theoretical and
observational perspectives. Rigid-body dynamics for principal axis and non-principal-axis …
