The Main Control Room at ESA’s European Space Operations Centre (ESOC) in Darmstadt today 
️
This room sees launches, landings, mission sims, & more, & has been the scene of some of the greatest days in ESA’s history (& mine).
The spacecraft the MCR talks to are in, err, space 
️, but several have siblings at ESOC, engineering models with the same electronics & software, used to test procedures before uplinking to the real thing.
