Saturn has a great many more moons than our planet – a whopping 62. A single moon, Titan, accounts for an overwhelming 96% of all the material orbit the planet, with a group of six other smaller moons dominating the Continue reading
This is very cute — Curiosity’s latest “selfie,” a mosaic made up of about a dozen images acquired with the rover’s Mars Hand Lens Imager (MAHLI) instrument on April 27-28, 2014 (Sol 613) with the 5.5-km-high Mount Sharp (Aeolis Mons) Continue reading
NASA’s Curiosity Mars rover reached the edge of a dune on Jan. 30 and photographed the valley on the other side, to aid assessment of whether to cross the dune. Curiosity is on a southwestward traverse of many months from Continue reading
Speeding toward pale, icy Dione, Cassini’s view is enriched by the tranquil gold and blue hues of Saturn in the distance. The horizontal stripes near the bottom of the image are Saturn’s rings. The spacecraft was nearly in the plane Continue reading
Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons. Lit terrain seen here is on the leading hemispheres of Rhea Continue reading
The international Cassini mission has spotted what appears to be a miniature extraterrestrial version of the Nile River: a river valley on Saturn’s moon Titan that stretches more than 400 km from its ‘headwaters’ to a large sea. It is Continue reading
Twin NASA probes orbiting Earth’s moon have generated the highest resolution gravity field map of any celestial body. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon’s internal Continue reading
Data from NASA’s Cassini spacecraft tie a shift in seasonal sunlight to a wholesale reversal, at unexpected altitudes, in the circulation of the atmosphere of Saturn’s moon Titan. At the south pole, the data show definitive evidence for sinking air Continue reading
This fantastic swirl of clouds at the Saturn’s north pole has been photographed by the Cassini spacecraft on November 27, 2012. The camera was pointing toward Saturn at approximately 224,618 miles (361,488 kilometers) away, and the image was taken using the Continue reading
The NASA Mars rover Curiosity began its flight to Mars on Nov. 26, 2011, from Cape Canaveral Air Force Station, Fla., tucked inside the Mars Science Laboratory spacecraft. One year after launch and 16 weeks since its dramatic landing on Continue reading
