The steep lee sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune. Dark splotches are places where ice cracked earlier in spring, releasing sand. Soon the dunes will be completely bare and all signs of spring activity will be gone.

Scientists expect that spokes will soon cease to form as Saturn approaches northern equinox. The exact mechanism of spoke formation is still the subject of debate, but ring scientists do know that spokes no longer appear when the Sun is higher in Saturn\'s sky. It is believed that this has to do with the ability of micron-sized ring grains to maintain an electrical charge and levitate above the rings, forming spokes. Thus, these may be some of the last spokes ever imaged by Cassini.
This view looks toward the unilluminated side of the rings from about 38 degrees below the ringplane. The image was taken in visible light with the Cassini spacecraft wide-angle camera on Oct. 22, 2013.
The view was obtained at a distance of approximately 1.6 million miles (2.6 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 146 degrees. Image scale is 93 miles (150 kilometers) per pixel.

Busy day at Bagram
There’s a lot to like in this shot posted to the US Air Force’s flickr stream. A pair of Lockheed Martin F-16 Fighting Falcons prepare to taxi out to the runway while a US Army Boeing AH-64 Apache helicopter takes off at Bagram Airfield, Afghanistan, all against a backdrop of snow-covered mountains.

Training underwater on a life-size mockup of the Space Station is one way astronauts prepare for their mission. Floating underwater is one of the best ways train on Earth for weightlessness.
