Peer-reviewed literature and official NASA/ESA sources report that high-resolution imaging from the Mars Reconnaissance Orbiter successfully identified the crashed Beagle 2 lander, which was deployed by the Mars Express mission.
The 2003 Beagle 2 Mars lander has been identified in Isidis Planitia at 90.43° E, 11.53° N, close to the predicted target of 90.50° E, 11.53° N. Beagle 2 was an exobiology lander designed to look for isotopic and compositional signs of life on Mars, as part of the European Space Agency Mars Express (MEX) mission. The 2004 recalculation of the original landing ellipse from a 3-sigma major axis from 174 km to 57 km, and the acquisition of Mars Reconnaissance Orbiter High Resolution Imaging Science Experiment (HiRISE) imagery at 30 cm per pixel across the target region, led to the initial identification of the lander in 2014. Following this, more HiRISE images, giving a total of 15, including red and blue-green colours, were obtained over the area of interest and searched, which allowed sub-pixel imaging using super high-resolution techniques. The size (approx. 1.5 m), distinctive multilobed shape, high reflectivity relative to the local terrain, specular reflections, and location close to the centre of the planned landing ellipse led to the identification of the Beagle 2 lander. The shape of the imaged lander, although to some extent masked by the specular reflections in the various images, is consistent with deployment of the lander lid and then some or all solar panels. Failure to fully deploy the panels-which may have been caused by damage during landing-would have prohibited communication between the lander and MEX and commencement of science operations. This implies that the main part of the entry, descent and landing sequence, the ejection from MEX, atmospheric entry and parachute deployment, and landing worked as planned with perhaps only the final full panel deployment failing.
The Mars Reconnaissance Orbiter is uniquely qualified to meet objectives required by human missions to Mars. Landing site characterization capabilities include imaging for boulders and terrain difficult for landing and/or driving, understanding soil compaction for future construction, plus locating resources such as sub-surface ice deposits and caves. During the entry, descent and landing phase, the UHF radio can provide real-time data return, while several instruments can provide weather and atmospheric density information. The high-resolution imager can capture photos of a vehicle mid-descent and after touchdown. These capabilities could prove vital for determining the root cause after an anomaly. Once human presence on Mars is established, the UHF radio can provide positioning information, relay data from equipment placed outside of direct communication with the landing site and possibly serve as a back-up communication system during extravehicular activities. Other MRO capabilities include creating stereo maps for extravehicular route planning, dust storm prediction and monitoring, atmospheric density measurements for aerobraking, improvement of spacecraft ephemerides to assist with precisely targeted landings and finding lost hardware in orbit and on the ground.

This annotated image shows a bright feature interpreted as the United Kingdom's Beagle 2 Lander with solar arrays at least partially deployed on the surface of Mars.
Beagle 2 was released by the European Space Agency's Mars Express orbiter but never heard from after its expected Dec. 25, 2003, landing. This and other images from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter have located the lander close to the center of its planned landing area.
The 10-meter scale bar indicates a dimension of 32.8 feet. The location is approximately 11.5 degrees north latitude, 90.4 degrees east latitude.
The image is an excerpt from HiRISE observation ESP_039308_1915, taken Dec. 15, 2014.

ESA - Beagle-2 lander found on Mars
The UK-led Beagle-2 Mars lander, which hitched a ride on ESA’s Mars Express mission and was lost on Mars since 2003, has been found in images taken by a NASA orbiter at the Red Planet.
Beagle-2 was released from its mother craft on 19 December 2003 and was due to land six days later. But nothing was heard from the lander after its scheduled touchdown, and searches by Mars Express and NASA’s Mars Odyssey mission were fruitless.
Now, over a decade later, the lander has been identified in images taken by the high-resolution camera on NASA’s Mars Reconnaissance Orbiter. The lander is seen partially deployed on the surface, showing that the entry, descent and landing sequence worked and it did indeed successfully land on Mars on Christmas Day 2003.
Close-up of Beagle-2 on Mars
“We are very happy to learn that Beagle-2 touched down on Mars. The dedication of the various teams in studying high-resolution images in order to find the lander is inspiring,” says Alvaro Giménez, ESA’s Director of Science and Robotic Exploration.
“Not knowing what happened to Beagle-2 remained a nagging worry. Understanding now that Beagle-2 made it all the way down to
