The Moon

Though the Moon completes an orbit of Earth in 27.3 days, it takes 29.5 to complete a cycle of phases due to our planet's motion around the Sun. Image Credit: iStock

The discovery may have implications for future manned missions to the Moon, given that a water supply would be an invaluable resource. However, most of the water ice is found in the shadows of craters, where temperatures never reach above -156°C. The Moon is tidally locked with Earth, meaning the same side always faces our planet, and given the Moon’s small tilt about its rotational axis, sunlight never reaches these cold regions. The M3 instrument was launched in 2008 aboard the Chandrayaan-1 lunar orbiter by the Indian Space Research Organisation. The orbiter operated until August 2009. M3 was able to detect the reflective properties of the water ice and confirm its presence by measuring how the ice molecules absorb infrared light.
