+ * 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.
