#  Somewhen in the year 2011, 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.
