Pluto updates from AGU and DPS: Pretty pictures from a confusing world

Emily Lakdawalla • December 21, 2015

Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.

Curiosity stories from AGU: The fortuitous find of a puzzling mineral on Mars, and a gap in Gale's history

Emily Lakdawalla • December 18, 2015

Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
