This impact, should it occur, would not delay terraforming, or cause significant long-term issues with Mars.
We also won't have the ability to really begin terraforming Mars anytime soon, with or without it.

Possible, but they won't be big enough fragments to worry about, and the odds of any given piece of ejecta heading toward earth are quite slim.

No and no.
We don't want to deflect it, and even if we did, we do not have time. It's better to observe it.
An impact of this size on Mars won't do anything to the rest of the solar system, or Earth, except maybe give someone some tiny martian meteorites to dig up well into the future.

No plausible mission to deflect such an object would ever be manned.

Almost no plausible mission to deflect such an object would ever involve trying to "blow the crap" out of it.

We have sent probes past comets and landed on an asteroid. We have the technology to intercept and deflect such object, if given forewarning and time to do so.
However, we have neither the time, nor anything close to a compelling reason, to want to move this object.

Have you never heard of Shoemaker–Levy 9?

It's probably too small an impact to do anything that significant, and because there isn't much of an atmosphere currently, much dibris tossed up will settle much more rapidly than they would on Earth. Some will persist longer for the same reason, and lower gravity, but they won't kick start terraforming.

Earth has been hit by similar objects.

This chance exists without Mars being hit, and would actually be ever so slightly higher if Mars didn't removing one NEO.

This impact couldn't "wreck" Mars.

This would be like spitting an ice chip at a passing train and worrying that it would ricochet into your car parked 12 blocks away.

It's not that big.

Searching around a bit, it seems it all sprung up from a JPL orbit-thingy-widget that showed the comet and Mars on top of each other. But that program is not precise enough and by current estimates the closest approach will be more than 2,000,000 kms away from Mars. Impact is still not ruled out completely, as they are still observing the trajectory (70~ days so far, which is kinda short for such a far away and relatively small thing), but don't get your hopes up.
It's far less likely to impact at this point than not.
People still like discussing the hypothetical.Edited by Blameless - 2/26/13 at 6:07am
