Almost, but not quite… the Opportunity rover is now driving to another area on the hillside where it is currently located, after attempting to reach a difficult rock target. The rover wasn’t quite able to get close enough to the target to conduct further studies, after driving on the steepest slope ever encountered by any rover so far, on Knudsen Ridge.
NASA’s Curiosity rover on Mars may have been stealing the spotlight in recent years, but the other rover, Opportunity, is still going strong after 12 long years. Opportunity has survived the harsh environment and various challenges for much longer than anyone anticipated, and now is taking on a new task: climbing slopes as steep as 30 degrees while searching for deposits of clay minerals which had already been detected by orbiting spacecraft. The region where Opportunity landed, Meridiani Planum, is mostly flat plains, but now on the rugged edge of the huge Endeavour crater, the rover is becoming something of a mountain climber.
We’ve all seen the commercials for the Energizer Bunny, which keeps going and going and going… it just never seems to stop. This makes for an interesting analogy with the Opportunity rover, which is just now passing its 12th anniversary on Mars. Not just 90 days, as hoped for, but 12 years and counting. Incredible. And in that time, Opportunity has helped to fundamentally alter our understanding of this fascinating world.
An interesting image from the Opportunity rover, sol 4023. There are a lot of little shavings-like bits on this brushed rock inside the Spirit of St. Louis crater. Are they just a peculiar result of the brushing of dust by the rover instrument or something else? Are they bits of the rock itself or other embedded material? Similar ones were seen once before, but they seem to be uncommon, even after most brushings.
Two new beautiful composite images, from two different rovers and locations on Mars. The first is a sunset in Gale crater, taken by Curiosity. Martian sunsets look bluish due to the light scattering effects of reddish dust in the atmosphere. The other image, from Opportunity, is of the scenic Lindbergh rock mound in the Spirit of St. Louis crater, on the rim of the huge Endeavour crater. A natural monument!
