ExoMars Trace Gas Orbiter has had a productive science mission so far (finding no methane, which is a puzzle). If the rover lands successfully, the orbiter is going to take on a second job: rover data relay. To prepare for that work, ExoMars TGO will make a subtle change to its orbit on 15 June that will place it on course to be in the right place at the right time to relay the arriving rover’s telemetry to Earth. In the meantime, ExoMars TGO is performing regular tests of rover relay with Curiosity, giving ESA controllers valuable experience, and NASA scientists more data return. NASA provided its Electra relay radio packages to ESA to make all this as seamless as possible.

Meanwhile, the new Rover Operations Control Centre is a huge sandbox (dirtbox?) for engineers to play in. It's much like the In Situ Instrument Laboratory at the Jet Propulsion Laboratory where I’ve seen engineers work with models of Curiosity, the Mars Exploration Rovers, and InSight. I assume that when they're actually using it for testing they don't light it quite so dramatically!
