The rovers are still my favorite NASA mission, for reasons I’ve already written about. Even if the rovers quit tomorrow, the rover science team of Steve Squyres of Cornell and company would still have decades of data to comb through and analyze. Last Friday, they published more of the Opportunity data in the journal Science (requires subscription) that documents the role that salty, acidic water and wind have played in sculpting the magnificent rock formations in the craters of Meridiani Planum.
But I still have my soft spot for Spirit, even though that robot is stuck in the sand with another gimpy wheel. The pictures from rover missions are amazing, the science is spectacular, but I’m still floored by the engineering and troubleshooting involved in maneuvering a robot in a harsh environment on a planet 100 million miles away. The mission engineers have managed these problems remotely for more than 5 years– I know my car would need a hand-on tune-up long before that.
That’s not to say that there isn’t hands-on testing involved, and apparently, those steps are underway on the ground at NASA’s Jet Propulsion Laboratory to find a way out of the sand.
I’m not a gambling woman, but my (Monopoly) money is on the rover and the engineers.
