+ *  Somewhen in the year 20xx, 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.
+ *
+ *  Please visit the project hompage at sat.mur.at for further information.
