;;
;; 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.
