July 27, 2013 - Mars Once Had an Oxygen Rich Atmosphere


NASA recently unveiled the first images from the Interface Region Imaging Spectrograph study of the sun. Suzanne Presto will tell us more...  We hear about new research that predicts that if large amounts of methane are released from thawing permafrost in the Arctic... the world could wind-up paying out an incredible amount of money. And the UK's Oxford University reports findings that Mars may have had an oxygen-rich atmosphere nearly 1.5 billion years before Earth.  We talk with one of the scientists who led the research. This and more are coming up for you on VOA's science, health and technology magazine, "Science World."
