Is there water on Mars? Where is the location of the water, and how much is their storage volume? It is not only a matter of science, but also related closely to the future manned mission and immigrants to the Mars. As the most similar planet to the Earth in the solar system, the surface of Mars is covered with thick soil layer. However, what is the component beneath these sediments? It is always a mystery for human beings. Recently, scientists have discovered abundant pure water ice in the exposed scraps in the mid-latitude region. This article presented the results and what have been discovered. We discussed the proof of exposed ice in the observed material. The formation of ice scraps and the history of ice records, were also discussed. In the end, we described the utilization of the water ice resources for future Mars missions.
