Almost, but not quite … The Opportunity rover is now driving to another area on the hillside […]

Pluto Once Had Rivers and Lakes of Liquid Nitrogen, New Horizons Data Suggests

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.

Pluto is a tiny world in the outer fringes of the Solar System; for many decades it was only a mere speck of light in even the […]

The Changing Bright Spots of Ceres: New Evidence for Geological Activity?

Artist’s conception based on a detailed map of the surface compiled from images taken from NASA’s Dawn spacecraft in orbit around the dwarf planet Ceres. New observations show that the bright spots change in brightness from day to night, suggesting that they change under the influence of sunlight as Ceres rotates, and may also indicate subsurface geological activity.

Destined to fly a slightly shorter increment than normal to the International Space Station (ISS), the Expedition 48/49 crew of Russian cosmonaut Anatoli Ivanishin, NASA astronaut Kate […]

New Study Suggests Mars' Ancient Surface Shifted and Tilted Due to True Polar Wander

A view of Mars showing the expansive Valles Marineris (center), which is the largest canyons system in the entire Solar System. Three of the four giant shield volcanoes that constitue the massive Tharsis region are seen at far left. A new study by an international team of planetary scientists has provided evidence that the formation of Tharsis had profound effects in the shaping of Mars' geomorphology and climate, ultimately tilting the surface by as much as 20 degrees relative to planet's axis of rotation.
