 *  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.
