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 the Solar System, and describe the various methods for detecting it, including remote sensing from ultraviolet to radio wavelengths. We review progress in the first decade of study of MBCs, including observations, modelling of ice survival, and discussion on their origins. We then look at which methods will likely be… 
The Asteroid-Comet Continuum
The practical distinctions between asteroids and comets, viewed as products of accretion on either side of the snow line, are less clear-cut than previously understood. In this chapter, we discuss
Cometary science with CUBES
The proposed CUBES spectrograph for ESO’s Very Large Telescope will be an exceptionally powerful instrument for the study of comets. The gas coma of a comet contains a large number of emission
Comet 66P/du Toit: not a near-Earth main belt comet
Context. Main belt comets (MBCs) are a peculiar class of volatile-containing objects with comet-like morphology and asteroid-like orbits. However, MBCs are challenging targets to study remotely due
Orbital Alignment of Main-belt Comets
We examine the orbital element distribution of main-belt comets (MBCs), which are objects that exhibit cometary activity yet orbit in the main asteroid belt and may be potentially useful as tracers
Search for Dust Emission from (24) Themis Using the Gemini-North Observatory
We report the results of a search for a dust trail aligned with the orbit plane of the large main-belt asteroid (24) Themis, which has been reported to have water ice frost on its surface.
Water transport throughout the TRAPPIST-1 system: the role of planetesimals
Observational data suggest that a belt of planetesimals is expected close to the snow line in protoplanetary disks. Assuming there is such a belt in TRAPPIST-1 system, we examine possibilities of
Analysis of the Karma asteroid family
The Karma asteroid family is a group of primitive asteroids in the middle part of the main belt, just at the outer edge of the 3J:1A mean-motion resonance. We obtained the list of the family members
The proposed Caroline ESA M3 mission to a Main Belt Comet
The Reactivation of Main-belt Comet 259P/Garradd (P/2008 R1)
We present observations of main-belt comet (MBC) 259P/Garradd from 4 months prior to its 2017 perihelion passage to 5 months after perihelion using the Gemini North and South telescopes. The object
The proposed Caroline ESA M 3 mission to a Main Belt Comet Journal Item
We describe Caroline, a mission proposal submitted to the European Space Agency in 2010 in response to the Cosmic Visions M3 call for medium-sized missions. Caroline would have travelled to a Main

Abstract As a recently recognized class of objects exhibiting apparently cometary (sublimation-driven) activity yet orbiting completely within the main asteroid belt, main-belt comets (MBCs) have
A Population of Comets in the Main Asteroid Belt
Optical data is presented showing the existence of a population of comets originating in a third reservoir: the main asteroid belt, which lends new support to the idea that main-belt objects could be a major source of terrestrial water.
Detection of ice and organics on an asteroidal surface
The spectroscopic detection of water ice and organic material on the asteroid 24 Themis is reported, a detection that has been independently confirmed and concludes that water ice is more common on asteroids than was previous thought and may be widespread in asteroidal interiors at much smaller heliocentric distances than was previously expected.
The Detection of Water Ice in Comet Hale-Bopp
Abstract We present spectra of Comet Hale-Bopp (C/1995 O1) covering the range 1.4–2.5 μm that were recorded when the comet was 7 AU from the Sun. These spectra show broad absorption features at 1.5
There are hints that the dwarf planet (1) Ceres may contain a large amount of water ice. Some models and previous observations suggest that ice could be close enough to the surface to create a flux
The Lifetime of Ice on Main Belt Asteroids
We theoretically estimate the loss rate of buried ice from spherical bodies 2-3.3 AU from the Sun. The loss rate is explored as a function of about a dozen parameters. We introduce the concept of a
Localized sources of water vapour on the dwarf planet (1) Ceres
The detection of water vapour around Ceres is reported, with at least 1026 molecules being produced per second, originating from localized sources that seem to be linked to mid-latitude regions on the surface.
Exposed Water Ice Deposits on the Surface of Comet 9P/Tempel 1
The direct detection of solid water ice deposits exposed on the surface of comet 9P/Tempel 1, as observed by the Deep Impact mission, suggests that the surface deposits are loose aggregates.
Perennial water ice identified in the south polar cap of Mars
This work presents the first direct identification and mapping of both carbon dioxide and water ice in the martian high southern latitudes, at a resolution of 2 km, during the local summer, when the extent of the polar ice is at its minimum.
