Arabia Terra has always been a bit of a martian enigma. Planetary scientist Joel Davis takes us on a tour of its valley networks and their significance in telling the story of water on Mars.
Deepak Dhingra reports on a planetary analog field trip exploring a very young volcanic terrain in Idaho at Craters of the Moon National Monument and Preserve.
In a paper released in Geophysical Research Letters today, Eugene Shalygin and coauthors have announced the best evidence yet for current, active volcanism on Venus. The evidence comes from the Venus Monitoring Camera, which saw transient hot spots in four locations along a system of rifts near Venus' equator. They saw the hot spots in two distinct episodes in 2008 and 2009.
At the Geological Society of America conference this week, Curiosity scientists dug into the geology of Gale crater and shared puzzling results about the nature of the rocks that the rover has found there.

Sand Waves in the Desert
or “Pet Peeves and Deciphering Climate Change in the Solar System”
I have a pet peeve: the words dune and ripple are often used interchangeably, although they are quite distinct from one another. So what’s the difference between aeolian dunes and ripples? And why should anybody care?

The Planetary Society released an official statement today recognizing the unprecedented achievement of maintaining an operating rover on the surface of Mars for a decade.
Planetary Radio: Rise of the Europa Underground?
Planetary Scientist Alyssa Rhoden and friends have created Destination: Europa
This week's PlanRad talks to one of the creators of a new effort to build support for the Europa Clipper, a spacecraft that would tell us far more about what's going on under that icy moon's surface.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research. Here's the next step in that journey: the Geologic Time Scales of Earth and the Moon.
Was there rainfall on Mars? Recent work mapping valley networks suggests there probably was -- but only for about 200 million years. What does this mean for life, and the Curiosity mission?
