Curiosity, NASA's Mars Rover, is roving. This 12-page eBooklet uses images from Solar System Live to show the positions of Mars and Earth (Mercury and Venus too) in their orbits on the day the spacecraft carrying Curiosity to Mars was launched (2011-11-26), the day Curiosity was gently lowered to the surface of Mars (2012-08-06), and the 1st and 15th of every month from September 2012 through September 2013 (26 images of the inner planets' orbits, four per page).
Hey, there is more: Solar System Live images of the inner planets' orbits at Mars opposition 2012-03-03 and conjunction 2013-04-17. Still more: Data, data, data about Mars and Earth, and a link to the Goddard Space Science Center where you can indulge your curiosity about Curiosity.

Most of our heroes are great mathematicians, physicists, and astronomers. Just for the fun of it, we wrote this 58-page document. It lists 53 mathematicians, physicists, and astronomers, one per page. For each entry, we show date of birth, the positions of the eight planets and dwarf planet Pluto on the birth date, a link to the person's Wikipedia web page, and a table of data about the eight planets, dwarf planets Pluto and Ceres, and Earth's Moon.
We also show you how to use the diagram of the planets' orbits to deduce what planets you can see and about what time of day (night) you can see them. We do this exercise with students we tutor – they like it.
