Life On Mars: Red Planet ‘Mysteriously’ Losing Water, NASA News Suggests
As NASA scientists try to get into more details about life on Mars, they fail to explain why the Red Planet has lost most of its water over the years. Over the last 3.7 billion years, 87 per cent of the water on Mars has been lost. And, even the best astronomers are unable to find out why. The loss of water has left the planet dry and barren, even though there was a time when there was enough water on the planet for life to exist, according to NASA news.
Curiosity, NASA's Mars rover, has got new data which suggests that the planet had little carbon dioxide 3.5 billion years back. The latest findings also suggest that there was not enough CO2 on the Red Planet to cause the greenhouse-effect and thaw water ice. But, NASA researchers have no clue what happened over the next period of time that caused the temperature of the planet go high, as the NASA news suggests.
Thomas Bristow of NASA's Ames Research Center in California said Curiosity examined sedimentary rock from the Red Planet. "We've been particularly struck with the absence of carbonate minerals in sedimentary rock the rover has examined," An F1 Blog quoted Bristow as saying. "It would be really hard to get liquid water even if there were a hundred times more carbon dioxide in the atmosphere than what the mineral evidence in the rock tells us."
There is enough evidence to suggest the possibility of life on Mars, which had water flowing. In addition, the Sun was around one-third less warm. That is why NASA scientists finding it difficult to understand how most of the water on the Red Planet disappeared. NASA's Mars rover discovered in June 2013 that Mars one had flowing water that was good enough for drinking. According to NASA news in September 2015, there is enough evidence to suggest that the Red Planet has flowing water at present,suggesting that life on Mars is still possible.
