* Somewhen in the year 2012, mur.at will have a nano satellite launched
* into a low earth orbit (310 km above the surface of our planet). The
* satellite itself is a TubeSat personal satellite kit, developed and
* launched by interorbital systems. mur.sat is a joint venture of mur.at,
* ESC im Labor and realraum.
