NASA discovery on MARS, impressive as it is, the discovery comes with some caveats. It's not like curiosity stumbled on a lost lake under a mountain or a stream trickling across the landscape. Rather, it found water molecules bound to other minerals in Martian soil. There's kind of a lot of it, too. Researchers say that every cubic foot of Martian soil contains about two points of liquid water. We tend to think of MARS as this dry place, to find water fairly easy to get out of the soil at the surface was exciting to me, " Laurie Leshin, dean of science at the Rensselaer Polytechnic Institute, told. She also explained how the discovery was made. Curiosity picked up and sieved a scoop of soil from the surface before dropping it into an onboard oven. We heat the soil up to 835 c and drive off all the volatiles and measure them. We have a very sensitive way to sniff those and we can detect the water and other things that are released.
The discovery of life on Mars is important for a number of reasons, but especially exciting because of what this means for future missions to Mars. We now know there should be abundant, easily accessible water on Mars, says Leshin. "When we send people, they could scoop up the soil anywhere on the surface, heat it just a bit, and obtain water. She makes it life on Mars sound so easy; now we just have to figure out how to get around that the quantity of deadly radiation we'll encounter on the trip over.
The MARS discovery of old mining equip as the results of Curosity's first 100 days on Mars, in the journal Science this week, also revealed the presence of a rock with a far more complicated chemical history than scientists expected to find on Mars. Coriosity is continuing its search for habitats that could have supported ancient microbial life. It already has found oe suitable location inside an ancient slab of bedrock near the rover's Gale Crater landing site.
