Creta 2002, SPIE Symposium on Remote Sensing CONCLUSION The MSG-1 has been launched successfully on the 28/08/2002. The S/C has reached its orbit one week later. The in-orbit storage (IOS) activities started on 09/09/02 including manoeuvres and spin-up to 100rpm, launch locking device disactivation, move of the mirror to a storage position of 45 degrees and decontamination. All the planned procedures for the IOS have been executed nominally and the decontamination has shown that all the environmental temperatures are found homogeneous confirming the on-ground TV testing results. The imaging will start at the end of October 2002. Creta 2002, SPIE Symposium on Remote Sensing
