Scientists find water ice on the moon which shows a possibility of a lunar colony for the humans. The NASA moon mineralogy mapper takes the telltale signature of frozen water in infrared measurements. An instrument that flew on India’s Chandrayaan-1.
Evidence of water on the lunar surface of the moon
The polar regions that are under permanent shade and away from sun rays show patches of water ice on the ground in some spots shows in a freshly analysed data.
The north pole and south pole of the moon could one day provide a source of water for the human visitors.
What leads to the presence of water on the lunar surface?
During the daytime, the temperature of the lunar surface can raise up to 100 C. However, the moon is slightly tilted at about 1.54 degrees resulting to no sunlight at the lunar poles. Due to shadowed craters on the poles, the temperature remains at -157C (-250F). This would create an environment where deposits of water-ice could stay stable for extended periods.
How potentially be helpful to human?
The presence of water on the lunar surfacecould potentially help in turning it into drinking water for the human visitors. The “split” of hydrogen and oxygen can help astronauts to fuel rockets. The split oxygen can also help the astronauts for breathing.
If there’s enough ice sitting at the surface – within the top few millimetres – the water might be accessible as a resource for future human missions to the lunar surface.
The presence of water ice on the surface of other Solar Systembodies like the north pole of the planet Mercury and on the dwarf planet Ceres is also evident.
