 The observations using the radar systems that were missed while the software patch was being put in place, had been performed at least once previously during the mission and are scheduled for observation again later in the flight.SRL scientists say the impact of the temporary pause is minimal on the scientific investigations under way.One observation completed during the night was of a controlled oil spill in the North Sea designed to test the radar's ability to discern oil spills from the naturally produced film caused by fish and plankton in the water.
