Two questions : 1/ Can anyone suggest some software to predict visibility windows for particular orbital planes (and related, when is the southern hemisphere visibility op for the lastest Titan launch). 2/ Does anyone know of IRC chats relating to Sat observing/space science ? Thanks in advance.... Merry X-mas to all from downunder (blue skys and Mir passes on New years eve, there are some advantages to standing upside down on the planet !!!)
