A large comet, said to be the size of the one killed the dinosaurs on Earth, is headed towards Mars.

Do you think it will kill all the dinosaurs on Mars also?

Oh no! Someone save the Curiosity! And the Opportunity!

That said, they're more interested in capturing images of a close encounter, and the whole impact thing seems to be more of a ratings grab.

We may not have the Opportunity to save our Curiosity. A shame.

The dinosaurs were supposed to have been killed by the afteraffects of an asteroid impact and not a comet--a big rock vs a big snowball--so I doubt a comet would have much of an affect on the Martians, although the water it brings would probably be good for their planet.

As far as I know we've still got one or two satellites orbiting Mars for mapping purposes. It would be interesting if they could provide immediate before and after pictures of the impact, should it occur.

When I heard about this comet (Siding Springs) & it's close encounter with Mars next year, I had to wonder if Curiosity & Opportunity were deliberately sent there to observe & record the event. I suppose it could be just a coincidence?

Here's a few stats I dug up:

"The core of the comet is 50 kilometers large"

"It was said that the comet was moving in the direction opposite to the planets of the solar system. Therefore, the speed in the possible impact will be very high - about 56 kilometers per second" (over 125,000 MPH)

"If it happens, the impact will produce an explosion, the power of which will be equivalent to 20 billion megatons of TNT."

"our Mars rovers and orbiting armada of planetary observation satellites will have a very intimate view of this historic moment. It has the potential to be a more impressive sight than Comet ISON’s inner-solar system trek later this year"

I was listening to Astrophysicist James McCanney on 'Coast to Coast' last night. He's the proponent of the electric universe theory & plasma discharge comet theory. He said the comet doesn't even have to hit Mars to put on a huge celestial show, it just has to come close.

I heard that too. I guess the bang, if it hits, would be a lot bigger than I thought. If it looks like it's going to hit or even come close, NASA should set up a worldwide pay-per-view. Revenues from that might pay their bills for a few years.
