John Batchelor and I did a quick 2015 year in review. We both agreed that the latest Falcon 9 launch by SpaceX was a potential game changer with the success of their flyback booster landing upright at the Cape. We also talked about the rest of this particular SpaceX mission which was just as impressive. For planetary science, we selected several mission for our 2015 best including New Horizons, Dawn, Akatsuki which started orbiting Venus after being lost for five years, and the Japanese Hayabusa 1 and 2 missions,. We commented that we were disappointed in the suborbital industry progress other than for Blue Origin and their recent successful test flight with their rocket return to the pad. John liked the European Rosetta Mission for Comet 67P and specifically the Philae lander. We summarized our short discussion by wishing everyone a very Merry Christmas and Happy New Year, plus we look forward to 2016 being another exciting year for space.
