And of course there's watching SpaceX launches; another one today, from which my pic is taken. It is just after second stage separation. Stage 1 has turned and has begun its "boost-back burn". What I find cute is that you can see any of this; the pic is a screen capture of video from the ground, and the Falcon 9 is 80 km up. Other cuteness: they've stopped scrubbing the soot off the sides before reuse. What's also cute is to compare the landing with a recent Blue Origin effort: notice how BO pretty well stops well clear of the ground, has a think, and gently descents. Whereas SpaceX have calibrated themselves rather more carefully and simply slow to zero at the ground. BTW, I noticed that they were very careful to be very nice to NASA this time.
But just being optimistic is dull. Happily, there's a recent James Hansen post I can take mild exception to. The offending text is I believe that the legal approach will become increasingly important in the future, because the judiciary is relatively independent of fossil fuel interests. The Guardian did an article on this. I've expressed my doubts about solving GW through the courts before - funnily enough, also in the Hansen context - although with my characteristic lack of clarity. But I've also said more clearly - though I can't now find it - that approaching GW through the courts just seems like a bad idea to me, doomed to fail, doomed to polarise further an already far too polarised situation.
