The collapse of Io's primary atmosphere in Jupiter eclipse

Editors’ Highlight— The issue whether sublimation from the surface or volcanoes primarily sustain Io's sulfur-rich atmosphere has been debated for more than 20 years. This paper presents the first direct observations of a collapse of the atmosphere when the moon goes into shadow, indicating that sublimation.... more

A Cluster of Water Seeps on Mars?

From Research Spotlights— The discovery of dense concentrations of recurring flowlike features in two Valles Marineris chasms could aid in the search for life and influence future exploration of the Red Planet. One of the most significant discoveries revealed by the Mars Reconnaissance Orbiter.... more

Reconstructing Catastrophic Floods on Earth and Mars

Sarah Stanley, Freelance Writer

From Research Spotlights— A new theoretical model suggests that ancient floods that carved canyons on Earth and Mars may have been much smaller but lasted longer than previously thought. Catastrophic floods dramatically altered ancient landscapes on Earth and Mars, and their scars linger today..... more

Carbon Dioxide Frost May Keep Martian Soil Dusty

David Shultz, Freelance Writer

From Research Spotlights— Teaser: Temperature readings acquired from orbit show that Mars’s surface gets cold enough at night to allow layers of solid carbon dioxide frost up to several hundred micrometers thick to build up near the equator. Much of the discussion surrounding science on Mars.... more

Curiosity Sends Curious Water Data from Mars

Sarah Stanley, Freelance Writer

From Research Spotlights— The rover’s neutron spectroscopy instrument hints at an unexpected trend: The upper soil levels in the layers of Gale Crater’s Kimberley formation seem to hold more water-associated hydrogen. On 6 August 2012, NASA’s Curiosity rover landed on a Martian plain in the.... more

Thicknesses of mare basalts on the Moon from gravity and topography

Editors’ Highlight— This paper provides new estimates of the thickness of the mare on the Moon derived from recent high quality measurements of the Moon's gravity field by the GRAIL spacecraft.  The mare are large volcanic deposits that form the dark features we see on the Moon. They record a critical.... more Earth & Space Science News
