Raw image from Cassini’s last-ever flyby of Titan, taken on April 21, 2017. Photo Credit: NASA/JPL-Caltech/Space Science Institute NASA’s Cassini spacecraft has now officially entered the last phase of its mission – the “Grand Finale,” with the last-ever close flyby of Titan and the first of 22 final orbits which will take the […] 
Artist’s conception of the proposed Europa lander, with sampling arm extended. Image Credit: NASA/JPL-Caltech For decades now, Europa has beckoned – this moon of Jupiter which is frozen on the outside but hides a global ocean on the inside – has so far only been visited by spacecraft during brief flybys. Scientists and […] 
View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer […] 
Mosaic of images taken by Huygens during its descent to the surface of Titan, from an altitude of about 6 miles (10 kilometers). Riverbeds formed by liquid methane can be seen near the center of the image. Image Credit: ESA/NASA/JPL/University of Arizona Twelve years ago today, one of the most incredible space missions […] 
Charon (upper left) and Pluto as seen by New Horizons on July 14, 2015. Photo Credit: NASA/JHUAPL/SwRI Charon is Pluto’s largest moon and, despite being so cold and remote from the Sun, has been revealed to be a fascinating and active world, just like Pluto itself. Residing in the far outskirts of the […] 
View of Sputnik Planitia on Pluto. This vast region of nitrogen ice provides clues that a subsurface ocean of liquid water exists on Pluto. Photo Credit: NASA/JHUAPL/SwRI Pluto, a tiny frigid world in the distant outskirts of the Solar System, has been full of surprises, as first revealed by the New Horizons spacecraft […] 
Artist’s depiction of data being sent by New Horizons back to Earth. Image Credit: NASA/JHUAPL/SwRI To say that the New Horizons mission has been a success would be a massive understatement; this first-ever spacecraft to visit Pluto has revolutionized our understanding of this distant, small world. Pluto and its moons are complex and […] 
For the first time, x-rays have been detected around Pluto, as seen by Chandra (inset image). Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Chandra X-Ray Center It has been 14 months since the New Horizons spacecraft flew past Pluto and its moons, but data still continues to come in, and new […] 
The discovery of huge faults on Pluto provides evidence for a possible liquid water ocean beneath the ice crust. Photo Credit: NASA/JHUAPL/SwRI So-called “waterworlds” have been found to be surprisingly common in the Solar System—small icy moons which have ice crusts but oceans of liquid water below the surface. These include Jupiter’s moons […] 
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, […] |
