NASA'S Martian atmosphere experienced ups and downs, influenced by the heat of the Sun. When in sunlight, the atmosphere expands, and vice versa.

CALIFORNIA, KOMPAS.com — NASA's robotic Missions that Curiosity to investigate the Martian atmosphere resulted in some of the results. One of them, successfully detected the whirlwind on Mars.

With Rover Environmental Monitoring Station (REMS), the six-wheel robot has to detect atmospheric phenomenon 20 Mars landings since August 6, 2012. Some of it, at least one phenomenon refers to the whirlwind.

Some characteristics refer to the whirlwind, i.e. changes in barometric pressure, wind direction changes, a change in wind speed, rising temperatures, and changes in ultraviolet radiation that comes to a sophisticated robot.

Whirlwind usually lift the dust on the surface of Mars, leaving traces. Based on Curiosity, observation trail Twister on the red planet were obtained through a pattern of dust visible from orbit. However, the Visual trace on the surface is not available. Chances are, the whirlwind does not raise a lot of dust.

The research also shows surprising facts about the direction of the wind on Mars. With the position of Curiosity in the northern mountains of Mars (a mountain rising from the crater Gale), the direction of the wind is supposed to be from North to South. As it turns out, the wind direction is from East to West, are more affected by the slope of the crater Gale.

"With the slope of the crater to the North and the slopes of Mount Sharp to the South, it might be more of a breeze wafts between the two slopes rather than moving from a height of Mount Sharp," said Claire Newman, Chief of investigative Research at the Ashima REMS in Pasadena, in NASA'S release, Thursday (15/11/2012).

The ultimate goal is Mars Curiosity mission as high as 5.5 kilometers. Newman said, "If there is no change in wind patterns when Curiosity drove the Sharp mountain later, it will be a surprise."

Other facts are obtained from observations of Curiosity this time is low tide the Martian atmosphere influenced by the heat of the Sun. In the afternoon, the hot sun tends to be high that the Martian atmosphere is inflated or experienced pairs. So vice versa in the evening.

The ups and downs of Mars affect the radiation received. When the atmosphere plug, then the radiation received less because some have been absorbed in the atmosphere. The ability to absorb radiation influence of the small possibility of the planet uninhabitable.

Researchers also identify seasonal and daily pressure cycle. Pressure tends to be higher during the daytime and lower at night. Seasonal pressures affected by carbon dioxide in the Martian atmosphere are trapped in ice in the winter and returns to the atmosphere began to spring.

Curiosity has made a number of valuable discoveries during its mission. This Robot found that Martian soil similar to the land in Hawaii, the flow of water on Mars, and to identify rocks of Mars rocks Earth-like. The Mission of Curiosity aims to find out whether Mars could actually support life.
