Martian Crater May Once Have Held Groundwater-Fed Lake

  A NASA spacecraft is providing new evidence of a wet underground environment on Mars that adds to an increasingly complex picture of the Red Planet’s early evolution. This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water. Image Credit: [continue reading]

Ice on Lakes and Seas at Saturn's Moon Titan

  A new paper by scientists on NASA’s Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing lakes and seas of liquid hydrocarbon on Saturn’s moon Titan. The presence of ice floes might explain some of the mixed readings Cassini has seen in the reflectivity of the surfaces of lakes [continue reading]

Titan's Seasonal Changes Affect It More Than Thought

  Detailed observations of Saturn’s moon Titan have now spanned 30 years, covering an entire solar orbit for this distant world. Dr Athena Coustenis from the Paris-Meudon Observatory in France has analysed data gathered over this time and has found that the changing seasons of Titan affect it more than previously thought.  An artist’s impression [continue reading]

Sailing the Seas of Saturn's Moon Titan

  Humanity has landed a rover on Mars. Now, say scientists, it’s time to land a boat on Titan. This outlandish scenario could become reality, according to engineers presenting their proposals today (27 September 2012) at the European Planetary Science Congress.  Paddle concept for TALISE probe. This rendering of the proposed TALISE probe shows one possible [continue reading]
