##  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.
