Flight Director Michel Denis confirms good separation of the @ESA_EDM module #ExoMars Signals from @ESA_TGO have been reacquired (1/2)
Signals from @ESA_TGO do not contain the telemetry (onboard status info) expected & this situation is now being investigated #ExoMars (2/2)

How did @ESA_TGO experience @ESA_EDM separation? With a little bump! Left rotation rates; right acceleration. All as expected! #ExoMars
