Hopelessly hoping to find life on Mars

Hope to find evidence of life on Mars by scientists The NASA Aeronautics Agency (NASA) has taken a step back when the latest information sent by Curiosity probe shows methane gas in the atmosphere of Red planet lower than previously forecast.

In the September 19 report, NASA led the analysis of data transmitted from the Curiosity vessel to show that the methane gas density in Mars atmosphere is only about 1.3 ppb (unit of measurement of rare gas density in gas. book).

This finding is much lower than the prediction made in March 2003, which states that the Red planet may have about 19,000 tons of methane gas, a gas produced by biological processes.

This finding also means that NASA almost has to eliminate the hypothesis of the existence of life on Mars and the prediction given earlier may be due to confusion in decoding the observed images from glass. Telescope set on Earth.

An author of the study, Sushil Atreya of the University of Michigan, said that there is no scientific explanation for the sudden disappearance of a large amount of methane in the air, so the discovery of Curiosity could comes to claim that previous speculation about the existence of large amounts of methane on Mars is misleading.

However, the head of NASA's Mars exploration program Michael Meyer argues that the collapse of the methane hypothesis does not mean that there is no longer the possibility of finding life on the Red planet. Instead, new discoveries will help better orient future space science research.

The Curiosity board landed on Mars in August 2012. Earlier, the ship had found many signs that the planet once existed with water and a supportive environment for microbiological life. Currently, Curiosity is on its way to conquer an 8km journey to the main exploratory location on Mars, Mount Sharp.

NASA said the study of this mountain is one of the main tasks in the two-year mission of the Curiosity vessel and can help determine when Mars survives life.
