The Search for water ice on Comets and Asteroids

The presence of water is considered one of the key ingredients for the formation of life on Earth. Indeed, current theories as to the origin of the Earth’s oceans suggest that the water located there originated from both comets and asteroids, with the exact fractional contribution still under discus...

description The presence of water is considered one of the key ingredients for the formation of life on Earth. Indeed, current theories as to the origin of the Earth’s oceans suggest that the water located there originated from both comets and asteroids, with the exact fractional contribution still under discussion. However, water is not unique to the Earth; it has been found hidden deep inside polar craters on the moon, as well as in its fragment OH form contained in moon regolith. It is believed to make up over two thirds of the mass of the giant icy planets Uranus and Neptune. It is prevalent in the form of ice throughout the outer solar system on the moons of planets, on Kuiper Belt Objects, and on comets.
