Dust storms are beginning to whirl around Mars as spring blooms in the southern hemisphere of the planet and along the equator where the Mars Exploration Rovers (MERs) are roving into their fourth year with a second banner month of exploration.
There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!
Winter time is observing time at the Oak Ridge Observatory in Massachusetts, when humidity is low and the sky is often clear. And so it has been for the Optical SETI telescope, which opened its doors in April 2006.
Located in the southern part of the continent of South America, Southern SETI has a continuous view of densest star-fields in our galaxy. And, since 1990, it has been sponsored and supported by The Planetary Society.
This amazing view was captured by the CIVA camera on Rosetta's Philae lander just four minutes before its closest approach to Mars on February 25, 2007. The spacecraft was only 1,000 kilometers above the planet.
It's easy to forget that Mars is another such world with cloudy weather and seasonally varying climate. This lovely image release from the CRISM instrument on Mars Reconnaissance Orbiter brings that point home.
