The transfer module carries three black-and-white cameras, which engineers can use to monitor the BepiColombo mission to confirm that different pieces of the spacecraft are deploying properly — and to take some pictures for us Earthlings during the long journey. Here, one of those cameras can see part of the module's solar power system.
