The dwarf planet Ceres turned out to be covered by ice

The dwarf planet Ceres is a rocky place that is located in the main asteroid belt between Mars and Jupiter and is based on research done by NASA, it also contains a lot of ice on its dark surface.

The study, published in several reports in the journals Science and Nature Astronomy can lead to commercial mining on asteroids for both robotic and human expeditions to the moon.

Is a NASA spacecraft named Dawn was surrounding the Ceres since March 2015, in the 14-months mission to study Vesta, the second largest object in the belt.

Based on the study, Ceres contains 10 percent water, now frozen into ice, according to a physicist named Thomas Prettyman of the Planetary Science Institute in Tucson, Arizona, which is also one of the researchers.

By studying the solar system on the objects like Ceres will provide an overview of how the system is formed. When compared with Vesta is dry, then the condition of Ceres is more like Enceladus and Europa, the frozen moon of Saturn and Jupiter. So also when compared with Earth, Mercury, Venus and Mars, Prettyman said further.

Scientists were still debating whether Ceres has a salty sea, which creates a perception will grow dwarf planet outside the solar system that might be able to accommodate life, said the deputy leader of Dawn mission, Carol Raymond of the Jet Propulsion Laboratory in Pasadena, California.
"By finding a place rich in water in the past, we can find clues to the likely life of the early solar system," Raymond said through a written statement.

The informations collected by Dawn shown, that Ceres using the water to form minerals. Then the scientists combining the mineral data with computer models to study the interior.. *** [EKA | FROM VARIOUS SOURCES | POPULAR MECHANICS | SPACE]
