Week of 27 March: the ECLAIRs and MXT instruments were taken out of the transport boxes and placed on mechanical supports. The electronic boxes of the two computers were tested on their own, then connected to ECLAIRs and MXT: “everything is ok”. Checks were carried out to verify the mechanical interfaces of the French instruments with the PIM (Payload Interface Module, between the instruments and the satellite). This ensures that ECLAIRs and MXT are aligned on the same optical axis. On Sunday, the French team discovered the city of Shanghai and in particular People’s Square with its cherry blossom trees.
