On the nucleus structure and activity of comet 67P/Churyumov-Gerasimenko
TLDR
Images from the OSIRIS scientific imaging system onboard Rosetta show that the nucleus of 67P/Churyumov-Gerasimenko consists of two lobes connected by a short neck, which raises the question of whether the two Lobes represent a contact binary formed 4.5 billion years ago, or a single body where a gap has evolved via mass loss.
Cassini Ion and Neutral Mass Spectrometer: Enceladus Plume Composition and Structure
TLDR
INMS data indicate that the atmospheric plume and coma are dominated by water, with significant amounts of carbon dioxide, an unidentified species with a mass-to-charge ratio of 28 daltons (either carbon monoxide or molecular nitrogen), and methane.
Subsurface properties and early activity of comet 67P/Churyumov-Gerasimenko
TLDR
Subsurface temperatures showed seasonal and diurnal variations, which indicated that the submillimeter radiation originated at depths comparable to the diurnal thermal skin depth of comet 67P/Churyumov-Gerasimenko.
Liquid water on Enceladus from observations of ammonia and 40 Ar in the plume
Since Cassini spacecraft images revealed plumes of water vapour and ice particles erupting from Saturn's moon Enceladus in 2006, the search for the water source has been on. Possibilities include
Magnetosphere Imaging Instrument (MIMI) on the Cassini Mission to Saturn/Titan
The magnetospheric imaging instrument (MIMI) is a neutral and charged particle detection system on the Cassini orbiter spacecraft designed to perform both global imaging and in-situ measurements to
The Zwicky Transient Facility: System Overview, Performance, and First Results
TLDR
The Zwicky Transient Facility is a new optical time-domain survey that uses the Palomar 48 inch Schmidt telescope, and the ZTF data system at the Infrared Processing and Analysis Center provides near-real-time reduction to identify moving and varying objects.
Ion Neutral Mass Spectrometer Results from the First Flyby of Titan
The Cassini Ion Neutral Mass Spectrometer (INMS) has obtained the first in situ composition measurements of the neutral densities of molecular nitrogen, methane, molecular hydrogen, argon, and a host
MIRO: Microwave Instrument for Rosetta Orbiter
The European Space Agency Rosetta Spacecraft, launched on March 2, 2004 toward Comet 67P/Churyumov-Gerasimenko, carries a relatively small and lightweight millimeter-submillimeter spectrometer
