Are you looking for a free and unique calendar that you can print out and share with family and friends? The 2011 International Space Station calendar is a 14 page printout with a beautiful front cover, an inner page with an exploded diagram of the station, and a page for each of the months.
When you visit the International Space Station homepage look for the 2011 calendar download link (6.8 MB PDF file) highlighted in red below. There is a mislabeled hi-res version available as well (the file name says 2010 but it is actually a 2011 calendar). – Thanks for the tip on the hi-res version Kevin!
