Opportunity Rover Spots Greeley Haven on Mars

NASA - January 25, 2012


Explanation: Where on Mars should you spend the winter? As winter approached in the southern hemisphere of Mars last November, the Opportunity rover had just this problem -- it needed a place to go. The reduced amount of sunlight impacting Opportunity's solar panels combined with the extra power needed to keep equipment warm could drain Opportunity's batteries. Therefore Opportunity was instructed to climb onto the 15 degree incline of Greeley's Haven, shown as the rocky slope ahead. The incline increased power input as Opportunity's solar panels now have greater exposure to sunlight, while also giving the rolling robot some interesting landscape to explore. Visible in the distance, beyond Greeley Haven, lies expansive Endeavour Crater, the ancient impact basin that Opportunity will continue exploring as the Martian winter concludes in a few months, if it survives.






Coronal Mass Ejection and Auroras

As expected, a CME hit Earth's magnetic field on Jan. 24th at approximately 1500 UT (10 am EST). The impact produced a G1-class geomagnetic storm and bright auroras around the Arctic Circle. As the storm crested, Goran Strand of Ostersund, Sweden, took a panoramic photo and wrapped it 360-degrees to create this composition, which he calls "Planet Aurora".
