Re: [meteorite-list] Possible that comet will hit mars next year!!!
Just out of curiosity, what could this mean for the space-craft currently orbiting Mars? I mean even if this misses (which it probably will) a comet tail is pretty big and I'm sure there would be a lot of debris reaching Mars. If orbiters go down then I'm assuming the rovers do too. This could have some consequences many may not have even considered yet.

Re: [meteorite-list] Possible that comet will hit mars next year!!!
Hi Jeff, New data puts it so strike likelihood increasing. http://spaceobs.org/en/2013/02/27/new-data-concerning-the-close-approach-of-comet-c2013-a1-to-mars/ If not an impact this means the planet will pass through the comet's coma. Lots of dust and gas. Meteor showers at the surface and all the hardware we have put there will be at risk. They are going to have to give some serious thought as to how to protect the MRO. My nephew at Oxford Uni calculated (roughly at the moment) that the apparent mag of the explosion if there is an impact would be between mag -3 and -6 as seen from Earth (variation due to uncertainty in diameter of comet nucleus). I am surprised that there has not been more about this in the news, especially since the Russian meteor.

Would that be cool or what Thanks for the post...perhaps could re-direct to the Moon by accident of error? A new lunarmeteorite would arrive faster than a Martian.

wow That could be something to watch! But Im affraid it could be end not only for Curiosity but also for mars exploration for dozens of years if not more.

Re: [meteorite-list] Possible that comet will hit mars next year!!!
If only we were a few decades ahead in our space tech, then we could make sure the comet hits mars at a low angle for high ablation and begin our terraforming efforts! The gases from a 50 km comet will be substantial! Not to mention the heat/energy from impact could help raise temperature, which would turn Mar's dry ice into even more atmosphere; a nice chain reaction. -Yinan On Wed, Feb 27, 2013 at 7:59 AM, Marcin Cimala mar...@meteoryt.net wrote: wow That could be something to watch!

Re: [meteorite-list] Possible that comet will hit mars next year!!!
Hello Graham, With the current orbit from the MPC, my simulation has it missing Mars by a little over 700,000km, or about the same distance again from the MRO as MRO is from Mars at its furthest (according to what I've read of its altitude above the surface). Of course, I think everyone is anxiously awaiting every update as we get closer, to close the gap on uncertainty! I've yet to be able to dig up orbital elements for MRO. By my simulation, HST will be on the other side of the planet from closest approach and its view will be occluded. I'd love to figure out where MRO will be though - assuming that this first-blush ends-up being anywhere close to reality, and MRO is in position to train its instrumentation on C/2013 A1, and being the same distance from the comet that it is from Mars, the science could be _incredibly fortunate_, MRO paying for itself twice! --- Jodie Wednesday, February 27, 2013, 4:38:24 AM, you wrote: Has anyone come across this yet...unlikelybut would be quite an event?

Re: [meteorite-list] Possible that comet will hit mars next year!!!
Break out the 100mm binoculars and get ready. Time to go comet chasin again. I have about 5 or 6 under my belt, but I'll need darker skies this time around. I'm now living on the outskirts of Tampa, and the light pollution is pretty bad here. I'll need to drive about an hour north of here and get out into boonies so I can catch some comets - when the time comes. :) Let's hope a 2013 comet puts on a big show like comet Holmes did.
