Curiosity is back to science operations, though the activities are limited in scope by the fact that conjunction is fast approaching. (When Mars is behind the Sun as seen from Earth, our ability to communicate with our Mars spacecraft is severely limited. Because we can't get data down from them and because we couldn't rescue them if something went wrong, they have to go into a reduced activity period, performing only extremely safe operations producing a relatively low amount of data from a command sequence lasting three weeks or so.)
They've dropped one more sample from the John Klein drill hole to SAM. I noticed in a Mastcam photo of the SAM inlet tubes that the rover has really accumulated some dust over the last few months. Compare the view of those SAM inlet ports taken on sol 90:
To this view, taken on sol 227:
If the rover team is still a little cautious with the drill and SAM and Chemin, the ChemCam team has clearly gotten comfortable with their laser gun. Check out this bit of sharpshooting: Chemcam performed a profile up the visible wall of the John Klein drill hole, shooting at five spots inside it and one just outside it.
They followed this feat by strafing the tailings pile. Pew pew pew! Jokes about Curiosity's laser are never going to get old. The day I think that shooting things with a laser-equipped robot on Mars is boring is the day I should quit writing about space.
