Comet Siding Spring is going to make a very close approach to Mars in October. Any comet dust that reaches Mars has the potential to inflict significant damage on the spacecraft orbiting the planet. As it turns out, however, Mars and its orbiters are likely to see very few, if any, impacts. Why?

After setting the new off-Earth rover distance record in July, Opportunity roved on in August, driving south along the eastern edge of Endeavour Crater's western rim to Wdowiak Ridge on its journey to the next big destination, Marathon Valley.
The Mars gremlins really had it in for Curiosity this month. A computer glitch and slippery sand conspired to delay the rover's progress toward Mount Sharp. And shifting rocks proved unsafe for drilling. The rover will continue driving toward Mount Sharp, departing Bonanza King without drilling, skirting Hidden Valley along a plateau to its north.
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.
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.
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.
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.
The Planetary Society has been selected as an education outreach partner on the just-selected NASA Mars 2020 Mastcam-Z instrument, led by Jim Bell, Planetary Society Board president and Arizona State University professor.
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.
One of the hot topics of the 8th International Conference on Mars was the nature of Mars' ancient past. Abigail Fraeman reports on our updated view of whether Mars was ever warm and wet.
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.
Several announcements for proposed missions to Mars and on the planning for a NASA return to Europa that highlight the contrasts in planning missions for these two high priority destinations.
