Active Planetary Space MissionsWe have a new location for information on planetary space missions. It's here at the Planetary Society. The chart is created by Olaf Frohn, and is updated every month. Free SoftwareStellarium is a fabulous planetarium program with a very realistic sky and simple controls. They've added some features in the latest version (0.18.2) and and a new rendering engine that may not be compatible with computers more than a year or two old without using command line options. See the Stellarium User Guide (pdf) under Command Line Options for options to try. My older laptop requires -a. https://stellarium.org. There’s also a web based version of Stellarium. It’s pretty much bare bones, but works much like the computer version. It’s located here: https://stellarium-web.org. Cartes du Ciel (Sky Charts) is a great telescope companion. It can be downloaded from http://astrosurf.com/astropc/. Virtual Moon Atlas is a great tool for reference at the telescope or desk. http://www.astrosurf.com/avl/UK_index.html. Celestia is a great 3D simulator of solar system objects and beyond. http://www.shatters.net/celestia/ Hallo Northern Sky is an interesting planetarium program. It seems not as polished as Stellarium, but has some cool features. I use it when planning star parties as a quick way to see what would be visible because it loads quickly http://hnsky.org/
