Unmanned Spaceflight.com _ Spirit _ Scientificamerican July 2005

This issue features a very nice geologic overview article titled "The Many Faces of Mars", by Philip Christensen. (The inventor of TES). The author is kind of amazed about how much the findings of Oppy and Spirit differ. Spirit being in what seems to be an ancient dessert without any traces of past liquid water and Oppy having landed on what appears to be an ancient lakebed. Great reading for only $5!

What you get for free:

-An editorial about the SpaceShuttle titled: "Lost in Space". (Need I say more?)
-An article by Mark Alpert called: Feeling the Pinch. Flying the Shuttle means cutting some science. (canceling the $4 million per year Voyager program is such an... "interesting" idea)

I bought it today, not online but dead tree version. But you guys beat me to it as alvays.
Looks interesting, and will provide me with some info on the results on the minerals at Burns cliff and Eagle crater. Image texts also describe 'geologically recent glacier flow' and landslides detected by spacecraft. With other texts on Mass and the Higgs field plus one on dinosaurs it will be the bedtime reading for the next couple of days.
