My Pick of Pic's Jan 10, 2004 A View From Spirit on Sol 5 An excellent view from the MER-A lander on its fifth Martian day. There are so many wonderful features visible in this composite frame that it is difficult to know where to start. The smooth depression that dominates the left side of the image has been dubbed "Sleep Hollow". It is likely an impact crater that has eroded by wind over millions of years. Interestingly, it seems that Spirit has already been there. The dark spots in the dust are probably airbag marks made as the lander bounced across the surface. There are numerous dust or sand drifts and wind tails around rocks that give a good indication of wind direction. And several peaks and hills can be seen on the horizon. These landmarks provide valuable clues to the rover’s exact location. The apparent slope of the horizon is due to the slight tilt of the landing platform. JPL Home for the latest news
