It was just a couple of days ago that NASA announced something pretty exciting about Mars. Its Curiosity rover had detected shockingly high levels of methane, suggesting an unseen geological or even biological process was at work on the planet. Signs of past or present life? Perhaps, but a follow-up reading has now generated more questions than answers.
Along with its original announcement of Curiosity’s methane findings, NASA said it would conduct another reading in short order to determine whether or not the elevated methane level was consistent. Well, its second reading revealed a dramatic drop in the amount of methane in the air, leaving scientists to wonder what is causing methane “plumes” on Mars.
