SOL1806-2F286696020EFFAZDHP1214L0M1_br.jpgStuck! - Sol 180654 visiteCaption NASA:"The Hazard Avoidance Camera on the Front of NASA's Mars Exploration Rover Spirit (Front Haz-Cam) took this image after a drive by Spirit on the 1806th Martian Day, or Sol, (such as January 31, 2009) of Spirit's Mission on the Surface of Mars.
The wheel at the bottom right of the image is Spirit's right-front wheel. Because that wheel no longer turns, Spirit drives backwards dragging that wheel. The drive on Sol 1806 covered about 30 centimeters (1 foot). The Rover Team had planned a longer drive, but Spirit stopped short, apparently from the right front wheel encountering the partially buried rock visible next to that wheel.
The Hazard Avoidance Cameras on the Front and Back of the Rover provide wide-angle views. The hill on the horizon in the right half of this image is Husband Hill. Spirit reached the Summit of Husband Hill in 2005".MareKromium

SOL1811-PIA11798.jpgDusty Solar Panels - Sol 181154 visiteCaption NASA:"NASA Mars Exploration Rover Spirit took this image using the left eye of its NavCam during the 1811th Martian Day, or Sol, of Spirit's mission on Mars (such as February 5, 2009). Contrast has been stretched to make dust on the Solar Panels more easily visible.
Engineering data from Spirit's power subsystem indicated that some dust blew off the Rover's Solar Array on the following day, Sol 1812 (such as February 6, 2009).
This image and one from Sol 1813 (such as February 7, 2009 - PIA11799) provide a before-and-after comparison of the dust visible on Spirit's rear Solar Array. The reduction in the dust coating is difficult to discern in the images. The Cleaning Event was detected by a change in electrical output from the Solar Panels.
Spirit's daily energy supply from the solar array increased by about 30 watt-hours, to about 240 watt-hours from 210 watt-hours. (Thirty watt-hours is enough to illuminate a 30 watt bulb for one hour.) Before the Sol 1812 cleaning, only 25% of sunlight hitting the array was getting past the dust to be used by the photovoltaic cells. That factor improved to 28% after the Cleaning Event.
Spirit took this image at about 14:49 MLT at Spirit's location inside Gusev Crater. The Rover's position was next to the Northern Edge of the low plateau called "Home Plate", visible beyond the Solar Panels".MareKromium
