There have been a number of attempts to find Beagle 2, but none have been successful. In 2004, the Mars Reconnaissance Orbiter (MRO) took images of the area where Beagle 2 was thought to have landed, but no sign of the lander was found. In 2015, the ExoMars Trace Gas Orbiter (TGO) also took images of the area, but again no sign of the lander was found.
The search for Beagle 2 is still ongoing, and it is possible that the lander will eventually be found. However, the chances of finding it are decreasing as time goes on, as the surface of Mars is constantly changing due to wind and dust.
