To say that 2015 has been a great year for planetary exploration would be an understatement, with fantastic new discoveries from around the Solar System. From our first ever close-up look at Pluto and its moons, to […]

The Saline Slopes of Mars: NASA Confirms Evidence for Flowing Liquid Water

False-color image of RSL on slopes in Hale crater. The blue color is thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site […]

Curiosity Rover Continues Journey Up Mount Sharp After Science Observations at 'Marias Pass'

After extensive investigations of rock layers in Marias Pass, a shallow valley near the base of Mount Sharp, the Curiosity rover is now heading southwest again, to continue gradually climbing the […]

Early Mars May Have Been Cold and Icy Rather Than Warm, According to New Study

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 latter, […]

The search for liquid water on Mars is one that has been on-going for decades. It can’t exist for long on the surface, as it will quickly sublimate into the cold, thin atmosphere. Aquifers deep […]

Follow the Water? No, Follow the Martian Salt

The next direction for NASA, in terms of searching for life on Mars, might not be “follow the water”—it might be “follow the salt.” Image Credit: NASA / JPL / MSSS
