You may have heard that the sometimes deadly Salmonella bacterium becomes stronger in microgravity. That was just one of the fascinating results of experiments Arizona State’s Cheryl Nickerson and her team have conducted in low Earth orbit. She tells us why she has such passion for this work. Emily Lakdawalla tells us to look down on Mars for an amazing view of Curiosity amid the dunes. Bruce Betts says look up at the Red Planet! Bill Nye can’t believe the Cassini mission may be in budget jeopardy.
