As we enter 2018, NASA’s Curiosity rover continues to be busy exploring on top of Vera Rubin Ridge, on the lower flanks of Mount Sharp. The rover is gradually […]

'Strange Life' on Titan? New Organic Molecule Discovery Could Mean It's Possible

Titan, as seen in radar images from NASA’s Cassini spacecraft, is a complex world with methane/ethane rain, rivers, lakes and seas. Could it support life of some kind? Image Credit: NASA/JPL

Saturn’s largest moon Titan is a bizarre place with a thick and hazy nitrogen atmosphere, vast hydrocarbon dunes and methane/ethane rain, rivers, lakes […]

Nearing the End: Cassini Prepares for Spectacular 'Grand Finale' Orbits at Saturn

Cassini is now entering the Grand Finale phase of the mission, which will end on Sept. 15, 2017, after the spacecraft plunges between the planet and rings 22 times. Image Credit: NASA/JPL-Caltech

NASA’s Cassini mission to Saturn has been one of the most successful and awe-inspiring ever, studying the giant ringed planet and its […]
