The NASA Curiosity rover made a remarkable discovery this week that may hint at signs of life on Mars
The surprising development, reported by The New York Times, brings legitimacy to the long-held notion that aliens may [ According to a measurement taken on Wednesday by NASA's Curiosity rover, scientists have discovered high amounts of methane in the air on Mars – indicating microbes could survive on the planet. As the Times noted, methane is typically just produced by living things
This is not the first time that scientists have found methane on Mars: In 2004, scientists reported the discovery of methane in the air, following three years of observations. "We are 99 percent confident," Dr. Michael Mumma, senior scientist at NASA's Goddard Space Flight Center, told The Times that news. "
However, in 2013, new measurements from the Curiosity rover found that the atmosphere contained very little or no methane, reducing the prospect of life on the planet. Study author Christopher Webster, director of the NDEA's Jet Propulsion Laboratory, described these results as "disappointing for many," in an interview with Business Insider in 2013.
, the project scientist for the mission, wrote to his team that "given this surprising result, we've reorganized the weekend to run a follow-up experiment," with the results of those observations expected on Monday
