Quite looking forward to ISON, (although I've seen enough "this one will be the brightest EVER" predictions fizzle out that I'm not counting any chickens) but this one could be a once-in-a-geological-age spectacular!

National Geographic:
Mars may have a really bad day next year on October 19th. That’s when there is a very slight chance a newly discovered comet may impact our neighboring planet, says NASA....
...If Siding Spring would hit, the force of impact may truly be monumental. Based on observations to date the comet nucleus could be a real monster – as big as 9 miles (15 km) to 31 miles (50 km) wide. With it’s velocity clocked at 35 miles (56 km) per second, the energy force of the collision could be measured in the billions of megatons, resulting in a crater hundreds of miles wide. This could be an impact that rivals the one that wiped out the dinosaurs 65 million years ago on our planet and would be bright enough to be even seen with the naked eye from Earth.

I sorta hope it hits. Can you imagine what the images from the Mars rovers would look like? Assuming they survive for a while, at least.

Nothing excites a geek like things that explode catch fire or self destruct. Bring on the collision.

i assume if they are far enough away to survive and colse enough to see something they will just see a dust storm.
