I have a sneaky suspicion that I will never be able to keep up with the Mars Phoenix mission and still be able to write about it when something special happens, so if you need your fix of the latest and greatest, here are some places to go:
NASA's page, of course.
The Arizona Phoenix page has lots of great background info.
Emily's blog at The Planetary Society.
Chris Lintott has been keeping tabs, and has videos of interviews with scientists on the Phoenix mission.
You never know what the HiRIse team will have.
Universe Today will always have article, of course, too!
Know any more? Leave 'em in the comments! You can use HTML to make the links, but it might get snagged by the spam filter. I check that pretty often, so don't fret if it gets swept up.
