I am aware of 15 possible meteor showers on Mars, need to verify the date of Sol 63 to see if it fits into any of those. <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

Hi MeteorWayne, It was on Sunday 7th March 2004. Hope that helps. BTW, I would like to see that list. Could it be posted or linked to on this thread please?

Not easily, although I do intend to summarize the data and post it. It's in a book, so I have to retype everything, and with my typing skill level, that ain't a good thing <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

A bit like me than. My typing skills are not up to much <img src="/images/icons/crazy.gif" /> . I just thought this was very interesting. First a possible Cepheid Meteor or Viking 2 Orbiter observation, than later on the Earth rose as the Morning Star, an interesting morning for the MER A Spirit. What ever the streak was, it is a first in planetary exploration. Also the first Earth observation as the Morning Star from Mars, so predawn twilight on Sol 63 is quite significant. <img src="/images/icons/laugh.gif" /> Andrew Brown. <div class="Discussion_UserSignature"> "I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Does anyone know if they are planning to observe comet Holmes with HiRISE? It must look awful from there! Also, it may have some scientific significance to observe a comet from 2 different angles (Earth & Mars).

3488 · Oct 31, 2007

Hi rasun, I like your suggestion very much. A great idea. HiRISE would show the comet very well indeed. I wonder if anyone in JPL has thought of this? Also the comet is likely to be visible in the martian night sky from the MERs too. From Mars, Comet 17/P Holmes is 1.330 AU. Also from Mars, Comet 17/P Holmes appears above the Square of Pegasus in Pegasus. Position of Comet 17/P Holmes as viewed from Mars. Interesting.

I dunno...Starry Night is giving me an distance between Mars and Holmes of ~1.2 AUs. Either way, the difference in brightness between there and here is less than a magnitude, though the coma will be noticeably larger. I'd dig a HiRISE view, myself.

3488 · Nov 2, 2007

Hi Thalion, I dunno either. Just done another Redshift chart, this time included the information for Comet 17/P Holmes from Mars. Friday 2nd November 2007. Over the last few days, looks like the distance has increased to 1.353 AU. Wonder why the descrepancy between Redshift & Starry Night? Seems strange.

You are always more than welcome MeteorWayne. Whilst trolling around, found this. To me it seems conclusive.

As the comet may reach naked eye visibility, just checked out the postion of Comet 8P/Tuttle as seen from Mars. Friday 30th November 2007.

Any ideas anyone?? MER A Spirit. Raw Pan Cam image Sol 1450. The Sun or a longer exposure of Phobos @ night Another here with excessive blooming. Common sense tells me it is the Sun, but the lighting seems a bit muted (short exposure or is the landscape Phobos lit)? Shame that JPL no longer displays the local Gusev / Meridiani times on the raw images of Spirit or Opportunity.

I take it that the images from the last post were of a low Sun over Gusev Crater? Anyway, last posting on this thread before the great switchover. Mars North Pole, Thursday 21st February 2008.

why is it that life withstand the conditions on mars? is it the temp? atmosphere? if there are ice caps doesnt that mean that there is water, if water exist, cant there be life?

Posted by swampcatYou are more than welcome swampcat. Also thanks for the explanation to the RonMaverick who was confused.MRO is orbiting Mars about 250 kilometres / 155 miles altitude.Also what about the below, the Jupiter MRO HiRISE observation from Mars orbit in January 2006? Also pretty cool.http://hirise.lpl.arizona.edu/jupiter.php

Also here, Earth seen from the surface, predawn by MER A Spirit Sol 63, one hour prior to sunrise. http://photojournal.jpl.nasa.gov/catalog/PIA05560 Unlabled.http://photojournal.jpl.nasa.gov/catalog/PIA05547 Labled.
