Artist’s conception of Pluto’s surface, with the distant Sun and largest moon Charon in the sky. The surface is frozen now, but evidence suggests that rivers and lakes of liquid nitrogen once flowed here. Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Alex Parker As has been discussed extensively now on AmericaSpace, […] 
View overlooking part of High Dune, which is covered in smaller sand ripples. The image is white-balanced, to show how the scene would look under more Earth-like conditions. Image Credit: NASA/JPL-Caltech Since landing in 2012, the Curiosity rover has seen a lot of varied terrain within Gale crater, including ancient riverbed gravel, sandstone […] 
The edge of a dark sand dune field can be seen in this white-balanced Curiosity image from sol 1115 (Sep. 25, 2015). Image Credit: NASA/JPL-Caltech/MSSS Mars is often referred to as a desert world, being bone-dry for the most part, with dust and sand blanketing most of the surface. Some regions are covered […] 
Sedimentary strata at the base of Mount Sharp as seen at the Kimberly location. The strata in the foreground dip toward Mount Sharp, providing evidence of the former lake-filled depression that used to exist before most of the mountain formed. Image Credit: NASA/JPL-Caltech/MSSS Last week there was the exciting news that Mars still […] Illustration of debris flows inside Istok crater on Mars, which have provided evidence of large amounts of flowing water and mud in the past. The flows are very similar to ones on Earth in Arctic regions such as Iceland. Image Credit: Nature Communications The fact that Mars used to have large amounts of […] 
Colored mosaic of lakes near Titan’s north pole. Image Credit: NASA/JPL-Caltech/ASI/USGS Saturn’s largest moon, Titan, has seas and lakes of liquid methane and ethane dotting its surface, but one question scientists have been trying to figure out is how the hollows in the ground, which hold the lakes, form to begin with. Now, […] 
Conceptual image of the two competing warm and cold models of early Mars. Image Credit: Robin D. Wordsworth The debate over whether Mars used to be warmer and wetter or colder and wetter earlier in its history has been a long and contentious one. Now, a new study suggests it may be the […] The SkyTEM sensor suspended beneath a helicopter over Blood Falls and the Taylor Glacier in Antarctica. Photo Credit: L. Jansan Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for […] The ULA Delta-II tasked with launching NASA’s SMAP Earth Science satellite / mission. Photo Credit: Mike Killian / AmericaSpace Mother Nature and a relatively minor technical issue forced ULA to keep their Delta-II rocket, and NASA’s SMAP satellite, grounded at Vandenberg Air Force Base in southern California the last few days, but as […] Artist’s conception of an ocean-covered aquaplanet. Image Credit: Christine Daniloff/MIT With so many exoplanets now being discovered on a regular basis by astronomers, the focus has turned to what number of them might be habitable for some kind of life. For life as we know it at least, that depends on a number […] |
