The construction of OSIRIS-REx has begun! Seeing the core structure being assembled demonstrated that OSIRIS-REx is no longer just a set of drawings and PowerPoint charts, it is starting to become a real spacecraft.

Joseph O’Rourke summarizes a recently submitted paper on tectonic activity on Pluto after the Charon-forming impact.
NASA selected 21 Participating Scientists to join the Dawn team in 2010, prior to Dawn's arrival at Vesta in 2011. Since that time, Dawn Participating Scientists have made enormous contributions to the mission, as they do for most other NASA missions.

For the last two years, NASA has been the shy partner refusing to get on the dance floor, and Congress has been the aggressive partner insisting on a dance now. Recently, NASA has said maybe on another night but only if it’s a cheap date. While NASA says no for now, Congress looks to be willing to slip the band a cool $100M – on top of $150M already paid – to keep the music playing, but (to keep the metaphor going) has not been willing to fully commit itself to paying the bigger bill to rent the dance hall. The dance, of course, is the continuing attempt by Congress to have NASA commit to a mission to explore Europa, and NASA’s attempts to delay a mission well into the 2020s.
