Water flows on Mars - the discovery changes the cosmic perception

The discovery of surface water flowing in the hot season in Mars is an important breakthrough, sparking hope for people to live.

Detection of water on Mars - Detection shocked the world

The US Aeronautics and Space Administration (NASA) said on September 28 that Mars existed on the surface of saline water, opening up hopes of finding life on the red planet.

Long ago, "ancient Mars was covered by a vast atmosphere, along with an ocean the size of two thirds of the Northern Hemisphere, about 1,609 km deep ," said Jim Green, director of science. NASA planet said. After an unspecified disaster, "the Martian climate changed drastically, water on the surface gradually disappeared".

In 2008, the scientific community confirmed on Mars that existed frozen water, including at both poles. However, the latest data from the Mars Reconnaissance Orbiter (MRO) revealed that the surface of the red planet also contains liquid water, creating opportunities for a number of life forms to develop and develop. Hydrated salt traces, eroded slopes are a consequence of the flow of salt water on the surface of Mars during the hot season, then freezing and disappearing in the cold season.

"Mars is not the arid planet as we once thought," Green said.

According to Mary Beth Wilhelm of the Ames Research Center (NASA), discovering hot water in the hot season in Mars raises hope for people to live. Purified water will certainly be unstable in Mars's harsh atmosphere, which is why salt water is likely to exist in freezing or evaporated during the hot and cold season.

Scientists once discovered water on the surface of Mars, freezing at its poles. However, they are still not sure about the origin of surface water. Wilhelm said she was optimistic because the new data would give scientists "a great opportunity to find the right place on Mars" that humans could use, even as a sign of live in salt, liquid and moisture in the Martian atmosphere.

"Water on Mars will be an important resource in the future, for human adventures to this planet," Wilhelm said.

NASA and other space agencies are struggling to find ways to provide enough water for humans in the mission to explore Mars. It takes $ 10,000 in fuel costs for 0.45kg of water to send to the universe, so if there is water available in the universe, it will save a lot of money.

The European Space Agency and NASA are searching for water on asteroids, hoping to tap water asteroid shell and transport it to the Moon or Mars soon. However, mining asteroids still takes many years to do.

President Barack Obama has called on NASA to send people to Mars orbit in 2030, in preparation for the landing of Mars. A Mars orbit takes at least three years, so detecting liquid water on Mars is an important step in the quest for red planet.

NASA is planning to investigate asteroids near Mars, hoping to find microscopic lifeforms that exist. Therefore, perhaps they are not present in Mars - the planet once had oceans and atmosphere.

" The existence of liquid water indicates the possibility of life on Mars , and if it does, we can find out how they survive," said John Grunsfeld, NASA astronaut's Steering Committee for Science. , to speak. "Is there an existence of alien life, no longer an abstract question, but now has become a specific question that people can answer."
