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 the […]

A Martian Paradox: Curiosity Rover Findings Raise New Questions About Water on Ancient Mars

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 billions […]

Long after its incredible encounter with Pluto and its moons in 2015, the New Horizons spacecraft is continuing its journey deeper into the Kuiper Belt in the outer reaches of the Solar System. Mission scientists and engineers are now preparing […]

PHOTOS: Dream Chaser Delivered to Edwards AFB for Next Flight Test

Sierra Nevada Corporation’s Dream Chaser spacecraft was delivered to NASA’s Armstrong Flight Research Center this week, where it will undergo several months of testing in preparation for its second approach and landing flight. The data SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, […]
