Continuing my Christmas shopping advice tradition, I’m again recommending that readers consider The Year In Space Desk Calendar and Year In Space Wall Calendar as gifts for others and as well as for yourselves. My wife has used the space desk calendar for years and years and I always have the wall calendar on my studio wall.
The calendars are published in co-operation with the Planetary Society and contain a profusion of wonderful space related images. Get a big discount on a new membership to the Planetary Society when buying a calendar.
There is also a free Year In Space Online Calendar.
