These turbulent clouds are on top of the world at Saturn. Our Cassini spacecraft captured this view of Saturn’s north pole on April 26 – the day it began its Grand Finale – as it approached the planet for its first daring dive through the gap between the planet and its rings. Although the pole is still bathed in sunlight at present, northern summer solstice on Saturn occurred on May 24, bringing the maximum solar illumination to the north polar region. Now the Sun begins its slow descent in the northern sky, which eventually will plunge the north pole into Earth-years of darkness. After almost 20 years at Saturn, our Cassini mission is expectedly coming to an end on Sept. 15. Hear from mission experts today, Aug. 29 at 2 p.m. EDT on nasa.gov/live.

Observing images of craters on Mars provides scientists insight into the water that carved them and the Red Planet's history of water activity.

What do you think this tadpole-shaped impact crater says about the water that used to fill it? Based on the terrain-height information and knowing that water always flows downhill, scientists were able to infer that the water in the tadpole crater was flowing down, and outward. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on our Mars Reconnaissance Orbiter. Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space mars
