NASA detects moisture from the soil of Mars, in the future the possibility of getting water on Mars

National Aeronautics and Space Administration (NASA) Unmanned vehicle "Curio City"Detected moisture from the soil on the surface of Mars. This means that there is a possibility of obtaining moisture in the future Murus manned exploration.

BBC News - Mars water surprise in Curiosity rover soil samples

The unmanned vehicle "Curiosity (Curiosity)" used in NASA's Mars exploration mission has discovered that it contains a relatively large amount of water component when it collects and analyzes soil on the surface of Mars. The results of this research areIt is published in the Science Journal of the United States of America.

Picking up the soil on the ground with a pickup tool equipped with curiosity, sifted through the screen, screened fine soil particles, and then analyzed with a steam analyzer called "Sample Analysis at Mars instrument (SAM)" We obtained about 2% moisture content.

Here is an external view of SAM. The sampled sample is analyzed for components from heated and vaporized (vaporized) gas.


Graph A shows mass analysis results of the four major components contained in the gas.


The ability to collect moisture from Mars indicates that there is a possibility of getting water locally at the time of future manned exploration and it can be said that it is a result that greatly advances space exploration.

However, from the soil, 0.5% perchlorate in weight ratio has also been detected, and since it is toxic to inhibit thyroid function, Dr. Laurie Leshin of the Rensselaer Academy of Arts and Sciences says " Removal of these harmful components will be a future task for the realization of hydration supplementation, and research will be promoted.
