Stories, updates, insights, and original analysis from The Planetary Society.
The United States Geological Survey recently issued an improved version of the Viking color map of Mars. This 40-year-old data set still provides the prettiest global-scale map of the planet.
Animated maps of the planets show the spheres in motion.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
An interview with Bruce Murray from 2001 about his perspectives on Mars science and exploration: past, present, and future.
A new slant on Martian landscapes from Mars Global Surveyor.
I've been waiting for the publication of this book for years. Phil Stooke's International Atlas of Mars Exploration, just published by Cambridge University Press, is an exhaustively awesome labor of love, chronicling the first five decades of Mars exploration in pictures, maps, and facts.
Jason Davis put together this neat summary of the checkered history of Mars exploration.
I've had a fun morning of noodling around learning how to write KML files, and have produced one for Google Mars that shows you all of the Mars Orbiter Laser Altimeter tracks that cross the area Opportunity has driven through already, as well as the area of Endeavour crater.
Or: Emily reads you the table of contents of Icarus.
Carbonate rocks should be all over Mars. But it's been hard to find carbonates—surprisingly so.
I think a goodly proportion of you readers have already figured this out for yourselves since it was launched last March, but I didn't download and install it until last weekend, so this is new to me: Google Mars is awesome.
The HiRISE public suggestion tool, called HiWish, is a Web site that allows you to log in and select a spot on Mars as a suggestion for where the HiRISE instrument should take an image.
The science team for Mars Orbiter Camera, or
Planetary cartographer Phil Stooke has been working on a cool project to compose and compare maps of Mars that show how we saw the planet throughout the Space Age.
An article in the September 26 issue of Science neatly explains why only the southern half of Mars is strongly magnetized.
We first spotted the strange bright feature colloquially known as
There have been so many missions to Mars, which have sent back so much data, that figuring out how to find images of places on Mars can be really overwhelming.
It's now been nine days since Mars Global Surveyor was last heard from.
During April 2005, the Mars Global Surveyor happened to pass relatively close to Odyssey and Mars Express. What resulted were remarkably clear pictures of human-made spacecraft orbiting and alien world.
