The electric sands of Titan



Atlanta GA (SPX) Mar 29, 2017
Experiments led by researchers at the Georgia Institute of Technology suggest the particles that cover the surface of Saturn's largest moon, Titan, are "electrically charged." When the wind blows hard enough (approximately 15 mph), Titan's non-silicate granules get kicked up and start to hop in a motion referred to as saltation. As they collide, they become frictionally charged, like a balloon rubbing against your hair, and clump together in a way not observed for sand dune grains on Earth - they ... read more

Mars dust storm west of Opportunity starting to abate
Pasadena CA (JPL) Mar 27, 2017
Opportunity is just outside the rim of Endeavour Crater, heading to the gully, named 'Perseverance Valley.' The large regional dust storm to the west of the rover's site has started to abate, although there is still a lot of dust in the atmosphere and rover energy levels are affected. On Sol 4672 (March 16, 2017), Opportunity drove over 141 feet (43 meters) to the south. Owning to the elev ... more
