'Lost' 2003 Mars Lander Found by Mars Reconnaissance Orbiter
NASA | JPL-Caltech | MRO | 2015 Jan 16
The Beagle 2 Mars Lander, built by the United Kingdom, has been thought lost on Mars since 2003, but has now been found in images from NASA's Mars Reconnaissance Orbiter.
A set of three observations with the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. They show that the lander survived its Dec. 25, 2003, touchdown enough to at least partially deploy its solar arrays.
Beagle 2 hitched a ride to Mars on the European Space Agency's long-lived Mars Express mission. It was a collaboration between industry and academia designed to deliver world-class science from the surface of the Red Planet. ...
HiRISE images initially searched by Michael Croon of Trier, Germany, a former member of the European Space Agency's Mars Express operations team, provide evidence for the lander and key descent components on the surface of Mars within the expected landing area of Isidis Planitia, an impact basin close to the equator. ...

Emily Lakdawalla, of the Planetary Society, has written an extensive
blog post about this, with lots of images and links.
I particularly liked this BBC article to which Emily linked:
What does Beagle2 say about how to handle failure?

NATURE:British Mars lander find is bittersweet victory
image: NASA/Goddard Space Flight Center
...Although images are not conclusive, Beagle 2 mission manager Mark Sims told journalists at a briefing in London that he was “very confident” that NASA had found the missing craft.
...When bouncing, the probe could have come down on a rock, or been unfortunate to land edge-on, where it was least protected by its airbags. Just like a bean can is more difficult to open if it's dented, on a damaged probe some of the solar panels could have been unable to deploy, says Sims. ...Data taken by the Mars Express orbiter after it released the lander suggests that at that time the planet's atmosphere may have been thinner than usual, so that it would have not sufficiently slowed the descent.
Yet another scenario is that one of the airbags may have failed to detach during landing and interfered with the deployment of the solar panels. Some interpretations of the images suggest an airbag is still attached, although their tan colour makes them difficult to pick out, he adds.
Sims says there are lessons to be learned from knowing Beagle 2’s fate. If he were to do the mission again, he would use a crushable airbag system that deflated on landing. He would also have put the antenna on the outside, so that contacting Earth would not depend on unfolding all the solar panels. Constraints on the mass and volume of Beagle 2 meant this had not been possible at the time, he adds...
