Rover Opportunity Dust Streaks


Here’s a “selfie” of the little rover Opportunity and dust streaks on the solar panels.  Solar panels which are otherwise remarkably clean. This rover, Opportunity has set the bar to which all future rovers will be compared at least in terms of longevity. Opportunity has been on Mars over 4300 Sols and traveled more than 42 km / 26 miles.

Make me wonder what Oppy’s twin Spirit looks like.  Of course Spirit stopped functioning in 2010 after over 2500 Sols and a very successful mission. Perhaps the MRO can capture a picture of it down the road.

Here’s what NASA says about the image:
This image from the navigation camera on the mast of NASA’s Mars Exploration Rover Opportunity shows streaks of dust or sand on the vehicle’s rear solar panel after a series of drives during which the rover was pointed steeply uphill.

The image was taken on March 21, 2016, during the 4,322nd Martian day, or sol, of Opportunity’s work on Mars. The rover’s location was on the north-facing slope of “Knudsen Ridge,” which forms part of the southern edge of “Marathon Valley.” During a forward, uphill drive on March 10 (Sol 4311), Opportunity’s tilt reached 32 degrees, the steepest ever for any rover on Mars. While the rover was so steeply tilted, accumulated dust on its deck was affected by vibrations from wheels slipping against the ground. Tilt in the same direction continued with two downhill drives in reverse between that ascent and when this images was taken.
