With the (possibly incorrect) thread title as it currently stands, this is a relevant and interesting read.
The interesting part was waiting 12 years for another orbiter to image the landing area to figure out what went wrong with Beagle 2.
If ExoMars/Schiaparelli never sends a signal indicating what happened, would NASA's Mars Reconnaissance Orbiter HiRISE camera been able to photograph Schiaparelli (the lander) and figure out what went wrong?
The Beagle 2 is 2 meters across and Schiaparelli has a 2.4 m diameter.
