Happy 3rd Birthday Planet Four!

Today marks the third anniversary of Planet Four’s launch.  We couldn’t do this without each and every volunteer who has contributed to the project over the past 3 years. To each and every one of you, thank you!

We made this birthday mosaic of Mars (a full glob image taken by one the Viking spacecraft) assembled out of  ~16000 Planet Four tiles. If you’re interested in making your own, we used AndreaMosaic

If you have a spare moment, classify an image or the red planet at http://www.planetfour.org. Onward to year 4!
