Hi all:
I have made some updates to Celestia Educational Activities to bring them up to date for 2013. These include references to the new planet around Aplha Centauri B, the landing of Curiosity on Mars, the progress made by the Dawn spacecraft to date, the retirement of the Space Shuttle fleet and other changes.
You can find the updates on my website at: http://gregs-educational.info I will also be updating the free files on motherlode in the coming weeks.
Enjoy
Frank
