Is there life on Mars ??? NASAs Curiosity rover has recently made a surprising find on Mars that could help scientists get one step closer to figuring out if the Red Planet has ever supported life. The 1-ton Curiosity rover also discovered a fleeting spike in the levels of methane at its landing site, Gale Crater. Over the course of four measurements in two months on Mars, average methane levels increased 10 fold before quickly dissipating, but the cause of the fluctuation is still unknown. Researchers are particularly interested in finding methane on alien worlds because living organisms produce an overwhelming amount of the gas on Earth. While finding significant amounts of methane on Mars isnt a sure-fire sign of past or present life — geological processes can also produce the gas — its still a good starting point, according to many scientists
