Life on Mars was in the underground?

Robotic spacecraft exploration of the National Aeronautics and Space Administration (NASA), on Mars has entered its 10th year. On the last mission by sending Curiosity to the surface of Mars, has yet to find clues for signs of life on the Red Planet.

So far, Curiosity and other rides monitoring results shows the Martian surface known is very cold, dry, and contains of deadly chemicals elements. In these conditions it is impossible for life forms to survive.

Starting from the condition, research is now beginning to switch targets. Scanning is no longer centered on the surface of Mars.

NASA Scientists suspect the simplest life forms on Mars may be hidden underground. If on Earth, microbes can live underground to a depth of more than 5 kilometers. The number of microbes in the soil is estimated half of all living inhabitants. 

Most of the underground microbial organisms represent some of the most primitive kind. These instructions indicated that the simple life always starts first in the basement.

"At least, hang in there for a series of cosmic impacts that destroy the earth," said researchers from NASA, Joseph Michalski, January 21, 2013. Cosmic impacts known as the Late Heavy Bombardment occurred range from 4.1 to 3.8 billion years ago.

The surface of Mars has one-third of the earth's gravitational force. Layer crust less dense and more porous than the earth. This condition, according to Michalski, making the water more easily seep into the basement. Therefore, finding traces of water on Mars is very important.

As has been reported previously that the United States Space Agency (NASA) found new evidence behind the latest portrait of a large crater on Mars.

The crater is named McLaughlin describe the existence of an ancient lake on Mars. Crater McLaughlin has a very large size. Diameter of about 92 kilometers. Bottom of the crater is also very deep so the water flows into the alleged underground craters some point in the past.

Image obtained by NASA's Mars Reconnaissance Orbiter spacecraft. NASA researchers say, this portrait reveals new evidence of the existence of a wet underground on Mars. "It suggests that life may never lived there," said NASA researcher, Monday, January 21, 2013.

Even the researchers still open the possibility of life on Mars. They believe the research about life on Mars may explain the origin of life on earth. Currently this crater in dry conditions. However, trace minerals and a host of other evidence showing where it used to be a large basin filled with water.

"McLaughlin crater gave the best evidence about the formation of carbonate in the lake environment," said Joseph Michalski of the Planetary Science Institute in Tucson, Arizona, and he rejected the theory of carbonates from outside the crater. *** [EKA | FROM VARIOUS SOURCES | SPACE | MAHARDIKA SATRIA HADI | KORAN TEMPO 4122-4123]
