Before I saw this post of yours, I started my reply to D P Pierce's post with "Wow indeed!" too. On 2/28/2013 12:04 AM, Joe Bauman wrote:

Wow indeed! It's probably too much to ask to witness such a collision twice in one lifetime. On 2/27/2013 11:12 PM, D P Pierce wrote:

A number of posts about this on the Minor Planet Mailing List. Some posts are serious, some not so much. http://tech.groups.yahoo.com/group/mpml/ Checked TheSky and found from here in N. Utah there'll only be a short window to observe Mars that evening: Sun will set at 1841. Nautical dark at 1940. Astronomical dark at 2012. Mars will set at 2145. patrick On 27 Feb 2013, at 23:12, D P Pierce wrote:

Too, that date is nearly six months after opposition. Mars will be very small and far away. Even at opposition in 2014, it's only 15 arcseconds in diameter. Six months later in October, it will be 6 arcseconds, and probably not high enough for good seeing. It would take one heckuva wallop to be visible at all, and then maybe only as a couple of single-pixel frames in a high-magnification video sequence. No visible dust plumes, no visible craters. We'll have to settle for what any operating Mars probes or Hubble can image and beam back home- which could be pretty amazing...don't get me wrong, if an impact happens, it's literally a world-shaking event- but at this early stage, I predict that even a direct hit on the earth-facing side almost certainly won't be an observable visual event for the amateur astronomer, so a lot of folks might be getting their hopes up for something as visually stunning through the eyepiece as SL-9 hitting Jupiter. It's not even going to be close. On Thu, Feb 28, 2013 at 7:19 PM, Patrick Wiggins <paw@wirelessbeehive.com>wrote:

Hoping cameras from the orbiting craft could possibly record the impact (or shortly thereafter)...? ________________________________ From: Chuck Hards <chuck.hards@gmail.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Friday, March 1, 2013 8:59 AM Subject: Re: [Utah-astronomy] Possible Mars comet collion 2014 Too, that date is nearly six months after opposition.

Yep, Rich, that's my hope- I mentioned it. On Mar 1, 2013 9:13 AM, "Richard Tenney" <retenney@yahoo.com> wrote:

Here is good info on Mars for the 2014 opposition: http://spider.seds.org/spider/Mars/Add/2014_MARS.htm Rich, MRO has been in orbit around Mars since March of 2006. It's primary mission goals were accomplished long ago and it's now in extended-mission mode. Whether it's still operating by October of 2014 is a big question. I believe Mars Odyssey is still operating, but it's been there even longer than MRO. Cometary debris will also pose a hazard for any orbiting spacecraft. If MSL is still operating on the surface, it will also be in extended-mission mode by October 2014.
