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.

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.
Beaming scientists all around, spectacular images on large TV screens, and the best - or at least most exciting - yet to come: such was the extraordinary scene at the European Space Operations Centre in Darmstadt, Germany, today as the European Space Agency's Rosetta spacecraft reached its cometary destination.
After a journey of more than a decade, Rosetta has finally arrived at comet 67P Churyumov-Gerasimenko. Confirmation of the successful rocket firing came at about 9:30 UTC via a webcast from ESA's Operations Centre in Darmstadt, Germany.
A new video shows what a traveler aboard Mercury's MESSENGER spacecraft would see as they zipped over the planet's north polar region.
Larry Crumpler updates us on the Opportunity rover, which now holds the distance record for a rover on another planet and is about to climb up its highest crater rim segment yet.
Seven science instruments will help the Mars 2020 rover identify biosignatures and understand the history of the rocks it encounters on the surface of the red planet.
NASA Announces the Suite of Science Instruments on its Next Mars Rover Today
Will search for signs of past life

Today marks the unveiling of the suite of science instruments that will travel to Mars to look for signs of past life and help determine samples to store for possible return to Earth. The next rover mission will launch in 2020.
A journey of nearly a decade is almost over. Rosetta is making its final approach to comet 67P/Churyumov-Gerasimenko, and the comet's strange shape is beginning to come into focus. As of today, the spacecraft is only 2000 kilometers away from the comet, and 8 days away from arrival.
For the last four weeks, the name of the game for Curiosity has been driving. But these weeks of driving have been more challenging than they used to be.
Despite the fact that it hasn't moved for 6 months, the plucky Yutu rover on the Moon is still alive. Its signal is periodically detected by amateur radio astronomers, most recently on July 19. A story posted today by the Chinese state news agency offers a new hypothesis to explain the failure of the rover's mobility systems.
Technically, Pluto science observations don't begin for New Horizons until 2015, but the spacecraft will take a series of photos of Pluto and Charon from July 20 to 27 as it begins the first of four optical navigation campaigns.
I could not wait to post these amazing new images of comet Churymov-Gerasimenko from Rosetta. The nucleus of the comet is clearly a contact binary -- two smaller (and unequally sized object) in close contact.
Opportunity got off to a bumpy start in June, but the Mars Exploration Rover (MER) mission pressed on, continuing the exploration of Murray Ridge at the western rim of Endeavour Crater.
