NASA revealed that its Curiosity spacecraft is about to find evidence of salt in the soil of Mars, as the space agency says that it could be a sign of life on the red planet, and planetary scientists from NASA's Goddard Space Flight Center were in Greenbelt, Maryland pull pictures and data from the probe.
The scientists found that organic or carbon-containing salts are likely to be found on the surface of Mars, which the agency says are chemical residues of organic compounds. The organic compounds and salts could have been formed through geological processes or were a remnant of ancient microbial life, indicating that the planet may have been habitable.
But the equipment on NASA's rover is not suitable for determining if it is truly organic, yet the team suspects this likely is the case.
NASA researcher James M. T. Lewis said, as well as adding more evidence to the idea of organic matter on Mars, direct detection of organic salts will also support the habitability of Mars in the modern era. If we determine that there are concentrated organic salts anywhere on Mars, we will want to investigate further in those areas, ideally deeper digging beneath the surface where the organic matter can be better preserved.
