MESSENGER is fast approaching the third and final Mercury flyby during its seven-year journey to the innermost planet.

A few weeks ago I gave a lunch talk at Cornell summarizing the MSL mission and particularly the instruments that it will carry and was shocked by the number of people who showed up!

Just a cool image to start the morning: after a 70-meter drive yesterday, Opportunity's following not one but two sets of its own tracks.

Greetings from Los Alamos New Mexico!

The images from the Lunar Reconnaissance Orbiter Camera or LROC are absolutely stunning.

There's a lovely new color HiRISE image of Spirit at Home Plate. It was captured on July 16 (sol 1,968), and Spirit is firmly entrenched at Troy, on the western side of Home Plate.

For a while, Mars was beating Spirit while she was down, throwing a dust storm at the rover where it's bogged up to its hubcaps in fluffy soil When lots of dust is lofted into the sky, the hazard is that when it comes down, it may come down on the rover and its solar panels. But it appears things on Spirit are still pretty clean.

High in the Arctic, just below Earth's north polar ice cap, biologists, geologists, and engineers come together in Svalbard every August to practice and prepare for an expedition to Mars.

While Spirit has been stuck at Troy, it's been taking numerous opportunities to capture photos with dramatic twilight lighting. On sol 2,002 (three sols ago, or August 21), it gazed toward the setting Sun, snapping the shutter roughly once a minute.

I really can't explain why it didn't occur to me to search for the rover in the image of Victoria crater released by the HiRISE team on Wednesday.

Today the HiRISE team released a lovely new view of Victoria crater, taken nearly a year after the Opportunity rover departed it.

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.

Samuel Lawrence

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?

Samuel Lawrence

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.
