DSCOVR is finally at L1 and transmitting back photos. I'm using that one as my new desktop background.

I remember being excited about this more than a decade ago; it's somewhat horrifying to realize that it took longer than New Horizons to reach its destination, though it was traveling through politics, rather than space.

(The non-spectacle value of this mission is at least twofold: the other side of it does solar measurements and replaces earlier CME early warning systems, and this side of it gives us a single temperature and albedo measurement for the Earth, helping with a handful of problems in climate measurement, and thus helping with climate modeling.)

You can see the smoke from the record-breaking recent Canadian and Alaskan wildfires in the photos. Those clouds drifted all the way over here to North Carolina shortly after those pictures were taken.
