Asteroids and comets are the remnants of the swarm of planetesimals from which the
planets ultimately formed, and they retain records of processes that operated prior to and …

The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

Comets are considered to be some of the most pristine and unprocessed Solar system
objects accessible to in situ exploration. Investigating their molecular and elemental …

Primitive objects like comets hold important information on the material that formed our solar
system. Several comets have been visited by spacecraft and many more have been …

Context. Since its rendezvous with comet 67P/Churyumov-Gerasimenko (67P), the Rosetta
spacecraft has provided invaluable information contributing to our understanding of the …

67P/Churyumov-Gerasimenko (67P) is a Jupiter-family comet and the object of investigation
of the European Space Agency mission Rosetta. This report presents the first full 3D …

Ganymede's atmosphere is produced by charged particle sputtering and sublimation of its
icy surface. Previous far-ultraviolet observations of the O i 1,356 Å and O i 1,304 Å oxygen …

Infrared observations of the coma of 67P/Churyumov–Gerasimenko were carried out from
2015 July to September, ie around perihelion (2015 August 13), with the high-resolution …

We review the evidence for buried ice in the asteroid belt; specifically the questions around
the so-called Main Belt Comets (MBCs). We summarise the evidence for water throughout …

UV photon-driven condensed phase cosmic ice reactions have been the main focus in
understanding the extraterrestrial synthesis of complex organic molecules. Low-energy (≤ …
