Chandrayaan-I Data Confirms Presence of Ice on Moon

The ice deposits are patchily distributed and could possibly be ancient, according to the study published in the journal PNAS.

Scientists have confirmed the presence of frozen water deposits in the darkest and coldest parts of the Moon's polar regions using data from the Chandrayaan-I spacecraft, that was launched by India 10 years ago, NASA said today. With enough ice sitting at the surface -- within the top few millimetres -- water would possibly be accessible as a resource for future expeditions to explore and even stay on the Moon, and potentially easier to access than the water detected beneath the Moon's surface. The ice deposits are patchily distributed and could possibly be ancient, according to the study published in the journal PNAS.

At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole's ice is more widely, but sparsely spread. Scientists used data from NASA's Moon Mineralogy Mapper (M3) instrument to identify three specific signatures that definitively prove there is water ice at the surface of the Moon. M3, aboard the Chandrayaan-1 spacecraft, launched in 2008 by the Indian Space Research Organisation (ISRO), was uniquely equipped to confirm the presence of solid ice on the Moon.

It collected data that not only picked up the reflective properties we would expect from ice, but was able to directly measure the distinctive way its molecules absorb infrared light, so it can differentiate between liquid water or vapour and solid ice. Most of the newfound water ice lies in the shadows of craters near the poles, where the warmest temperatures never reach above minus 156 degrees Celsius. Due to the very small tilt of the Moon's rotation axis, sunlight never reaches these regions. Previous observations indirectly found possible signs of surface ice at the lunar south pole, but these could have been explained by other phenomena, such as unusually reflective lunar soil.

Learning more about this ice, how it got there, and how it interacts with the larger lunar environment will be a key mission focus for NASA and commercial partners, as humans endeavour to return to and explore the Moon. NASA's Jet Propulsion Laboratory designed and built the moon mineralogy mapper instrument and was home to its project manager. The Chandrayaan-I spacecraft, India's first lunar probe, started suffering from several technical issues and stopped sending radio signals on August 28, 2009. Shortly after this, ISRO officially declared the mission over. The probe, which was intended to operate for two years, achieved 95 per cent of its planned objectives in under a year of its space journey. In 2016, NASA used ground-based radar systems to relocate Chandrayaan-1 in its lunar orbit. Repeated observations over the next three months allowed a precise determination of its current orbit.
