The instrument, called SOSP, was on board the EURECA satellite: European Retrievable Carrier. This satellite was deployed by the remote manipulator arm, on 1rst August, 1992. The spacecraft thrusters were fired to boost EURECA to its planned operating attitude of about 310 statute miles. One year after, it was to be retrieved on STS-57. The satellite was pointing the Sun during all the mission. Scientific data were got, on ground via ESOC (Darmstadt), directly in our institute and in near real time.
