Still wondering how we blasted an SUV-sized robot to Mars last year? Curious what the Curiosity rover is doing up there right now?

The truth is that scientists get no training at all in communicating with the public or even our students. And that's a shame, because if the public doesn't understand what science or spacecraft are good for, then eventually they will demand that our tax dollars stop supporting it.

Continued testing and updates of mission plans continue to assure that the Curiosity rover's drill will operate as planned, when needed, for the primary mission and beyond. Now let's go drill some rocks and get on with the exploration of Mars!

Until we understand our climate problems, and until we've developed solutions to deal with them, I'm not especially curious about Mars. "Danger, Will Robinson, danger!" With so much climatic uncertainty and so much at stake here at home, we can't afford to get lost in space.

We are dealing with the beginnings of what could end up being life, or pre-life, or at least simple organics on Mars. Whether the agency will step up to the plate and properly seize this priceless moment is an open question.

Finding life on Mars would be an amazing discovery, one that I truly hope we realize -- not to alleviate the mundane trappings of our existence, but more so to bring their lessons into sharper focus.
