The Many Hues of Mars.
I placed in the online group for the Mars Society-Chicago a report I intended to present to the 6th International Mars Conference.
It wasn't selected to be presented at the conference. However, if any one wants to read it, go to:
mars-chicago · This is the Mars Society - Illinois / Chicago Area Chapters Mailing List.
http://groups.yahoo.com/group/mars-chicago/
It's in the Files section under the title "The Many Hues of Mars."
You'll need to do a free registration to become a member of the group to access the files.
