Like all good journals this journal has changed over the years. Once a personal journal, then a travel journal I have returned this journal to the spirit of what a blog is and moved the travel aspect to one of my websites.

Water Ice at Mercury's Poles
The MESSENGER spacecraft has sent back evidence that Mercury has keep secrets in the shadowy craters at its poles. MESSENGER used three tests to reveal the evidence of water ice.
Using over 10 million laser pulses from MESSENGER's Mercury Laser Altimeter (MLA), MESSENGER has provided scientists with the first detailed models of the surface and near-surface temperatures of Mercury's north polar region, revealing evidence of thermally stable water ice.
Scientists have speculated for over 20 years on the possibility that Mercury might have water ice in its shadowed polar regions. MESSENGER has provided evidence that yes, there is water ice hiding away in the shadows of the Sun's closest planet's poles.

NOTICE: I love trying to make this a good travel journal and while I know I fall short of my dream, I also spend a LOT of time pondering and rereading comments to see if I should post or delete as robot SPAM. So... a few rules on the comments.
I want anyone, not only Blogger members or Open ID members to be able to comment, however... Please sign your comment, if you do not it will not be published. Anonymous comments help no one and are unreliable.
Also, if you have a strong enough opinion to post a comment, please take time and make it informative - if you had a good time somewhere detail what you mean, don't just say "This place was great!!! Loved the buffet!", and if you had a lousy time please detail it, don't just say "This place sucked and the pool smelled! Ruined my vacation!" I want to feel as if you really were there when I read your comments.
If you have a website or blog where you detailed your experience it is even better, include a link to your website or blog - just make sure it is not to a SPAM site made to endorse/defame a location, because I will delete any that do not strike me as being legitimate personal sites.
Thank you for your help in making it easier for me to know what is robotic SPAM and what are real personal reviews.
