America is about to launch a ship to Mars

There is evidence that Mars once had a thick and dense atmosphere, enough to hold water on its surface. (Image: postrecession.wordpress.com)

NASA's announcement guide AFP said the project of manufacturing spacecraft to Mars will be spent 438 million USD. The ship will be launched in November 2013 with three devices.

Many evidence that scientists have collected suggests that Mars once had a dense atmosphere capable of holding water on the surface. Water and air are two essential types of life. However, most of the atmosphere on Mars disappears due to climate change on the red planet.

Scientists believe that the atmosphere of Mars disappears due to the effects of magnetic storms that the sun creates. The red planet cannot resist storms since its magnetic field has disappeared.

Joseph Grebowsky, a scientist at Goddard Space Center in the US, said that many studies show that Mars can lose air by solar activity in many ways. Thus, NASA's future spacecraft will explore the causes of Martian air entering space.

" This project is very important for past, present and future Mars expeditions, " said Michael Meyer, a scientist from NASA's Mars Exploration Program.
