Saturn is truly the “Lord of the Rings” and one of the most majestic places in the […]

NASA's Low-Density Supersonic Decelerator Wraps Up Second Test Flight

From NASA: “LDSD is proceeding toward launch. The large scientific balloon – 34.4 million cubic feet in volume, has been undoing inflation over the last hour. When launched, the balloon and the test vehicle stand at a towering 980 feet tall.” The second test of LDSD took place Monday, June 8. Photo Credit: NASA

While Curiosity and Opportunity are still busy roving Mars, NASA has begun testing its next lander, InSight, scheduled to launch in March 2016. It will be the first mission devoted to studying the interior of […]

'Ocean Worlds Exploration Program': New Budget Proposal Calls for Missions to Europa, Enceladus and Titan

Artist’s conception of Europa’s interior, with water rising through cracks in the surface, depositing salts similar to sea salt on Earth. The ocean below may be a habitable environment for some kind of life. Image Credit: NASA/JPL-Caltech

The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which […]

Dark Material in Fractures on Europa's Surface Is Sea Salt, New Research Suggests

The darker-colored material within the fractures and elsewhere on Europa’s surface might be sea salt brought up from the ocean below. Image Credit: NASA/JPL/Ted Stryk

For over a decade, scientists have been curious about the long fractures on Europa’s icy surface and the darker-colored material they contain, as well as other relatively young geological […]

Enceladus' Water Geysers May Be 'Curtain Eruptions' According to New Study

The water vapor jets on Enceladus are now thought to mostly be more like diffuse “curtains” rather than separate plumes. Image Credit: NASA/JPL-Caltech/SSI/PSI

The water vapor geysers on Saturn’s moon Enceladus are one of the most fascinating phenomena in the Solar System; the jets spray far out into space in a dazzling display unseen […]

New NASA NExSS Coalition to Lead Search for Life on Distant Exoplanets
