Note that the lander is Schiaparelli, TGO (Trace Gas Orbiter) is just the "mothership" which it uplinks to; TGO achieving orbit, though, is still a special achievement.
Schiaparelli being lost is a 'well, go figure' moment; TGO being lost is an utter disaster.
Unfortunately landers are sexy, while science-rich orbiting probes aren't, so it's Schiaparelli that's getting all the press.
