I loved this video from NASA but could not help but reflect on the fact that I had seen all before... http://www.jpl.nasa.gov/news/news.php?release=2013-360

Ah Cool! And thanks!!!

Ah cool! This is most appreciated.

Hi Downloaded charts but my angles are funny when I try to use a paper drawn protractor. However, I noticed that you use a nifty on-screen protractor in your screen shots. Can you tell me where to get it so that I can use it with your charts? Thanks
