Rosetta spent the week transitioning to a lower orbit from which it continues to observe the comet. This weekend, the mission will select about five landing sites for more detailed study. They have also now estimated the mass of the comet.
Tanya Harrison reports on Canada's efforts to simulate a Mars sample return mission here on Earth.
Now that a Tiger Team has assessed the nature and causes of damage to Curiosity's wheels, I can finally answer your frequently-asked questions about what wheel damage means for the mission, and why it wasn't anticipated.
Opportunity just completed its first drives upslope on its long journey toward the crest of the highest rim segment of Endeavour crater, “Cape Tribulation.” Larry Crumpler gives us an update on what to expect next from the little rover that could.
Interstellar Dust Grains Found by Stardust@home
(and The Planetary Society Helped)
Seven possible interstellar dust grains have been found by Stardust@home, a citizen scientist project that The Planetary Society helped out early on. The dust grains would be the first ever examples of contemporary interstellar dust.
Rosetta has nearly completed its first funky three-cornered orbit in front of the comet. Each day we're getting views of the nucleus from more directions. I step you through Churyumov-Gerasimenko's geography.

"A Spacecraft for All" is a new website by Google Creative Labs that will host citizen science data from the ISEE-3 Reboot Project.
Now that we have reasonable confidence that our Mars orbiters will be safe from the close passage of comet Siding Spring, we are free to be excited about the opportunity that the encounter represents. At a community workshop on August 11, representatives from Mars missions shared their plans for great comet science.
Jason Perry brings us a report on recent ground-based observations that shed new light on the most powerful of Io’s volcanic eruptions.

It's official: Opportunity has traveled farther and lived longer than any other vehicle on another planet, driving to a place in history with an out-of-this-world distinction no one even imagined when the robot field geologist left Earth 11 years ago.
What's that in the distance? A binary star? Those are two little round worlds dancing in circles, whirling around a point in space located between the two of them. It's Pluto and Charon, clearly separated by New Horizons' camera.
On October 19, 2014, Comet Siding Spring is going to have an extremely close encounter with the planet Mars. The bottom line: it seems most likely that our Martian spacecraft will be absolutely fine.
