Now that it's high summer in the Arctic, it's time for research expeditions to swarm northward to explore icy landscapes as analogues to Mars and other far-off places.

Jani talks about the importance of understanding analogs we can easily visit on Earth to processes happening across the solar system.

The Cassini spacecraft made its 59th flyby of Titan, Saturn's largest moon, on Friday, July 24, and in the last few hours we have received images from the RADAR instrument in SAR (Synthetic Aperture Radar) mode.

For over four decades, the lunar science community has absorbed the information from the Apollo missions. Although many important questions were answered, many important new questions are waiting to be tackled -- which is the very essence of science and exploration.

One primary goal of the LRO mission is to acquire the amazing bounty of scientific data necessary to enable future human lunar exploration and utilization. But why should we even bother going back?

It is a day where when all humans should take time to celebrate the momentous achievement that put two brave explorers on the face of another world. As Sir Arthur Clarke once famously said, the Apollo voyages will likely be the only events for which the 20th century will be remembered in the future, when humans live throughout the Solar System and beyond.

Grab your bell bottoms and Tang, and travel back to 1969 when Apollo 11's journey to the Moon captivated the world, and Neil Armstrong's and Buzz Aldrin's boot prints in the lunar dust transformed us into a multi-world species.

Buzz Aldrin

Apollo 11 astronaut Buzz Aldrin and Planetary Society founder Lou Friedman argue that it is time for humans to go beyond the Moon.

Each Titan flyby is not a fork in the road, but rather a Los Angeles style cloverleaf in terms of the dizzying number of possible destinations. So how did our current and future plans for the path of the Cassini spacecraft come to be? That's the question Dave Seal put to me since that's my job -- I am a tour designer.

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

David Seal explains the complications for Cassini coming from Titan's atmosphere and Solar Cycle.

David Seal muses on his time as the mission planner for Cassini, and the history behind its name, and astronomy in Rome.

Well, it looks like the next-generation rover that will be launching to Mars in 2011 (and happens to be the focal point of my PhD thesis) just got a name!

Sometimes it is a bit awkward being a planetary scientist.
