Using an "image stacking and matching technique" called Super-Resolution Restoration (SRR), they've pieced together a zoomed-in version of the photo of the probe issued by Professor Mark Sims from the University of Leicester last year that confirmed the fate of the Beagle 2.
The new image gives a clearer look at the crash site and gives stronger evidence that the white mark on the planet's surface is indeed the probe.

When zoomed in further, the bright spot begins to resemble the ill-fated probe, which was launched by the European Space Agency back in December 2003 but lost contact with Earth and wasn't seen until last year.
The clearer image adds credence to the theory that it did in fact land on Mars but failed to unfurl its solar panels.

"Given the size of Beagle 2, even with super-resolution images you are not likely to see more than a series of blobs because it is so small," Sims, who worked on the original photo, said.
"What it does show is that it is on the surface and it is at least partially deployed."
The UCL team have released images of other parts of Mars, too, including the lake beds discovered by NASA's Curiosity rover, NASA's MER-A rover tracks and the Home Plate plateau.

The SRR technique stacks and matches pictures of the same area from different angles, allowing researchers to improve on the 25cm resolution limit on cameras currently orbiting Earth and Mars. The technique allows objects as small as 5cm to be seen from a 25cm telescope, the researchers say.
The scientists used between four and eight images of the surface of Mars taken with NASA's HiRISE camera to achieve the 5cm target resolution.
"We now have the equivalent of drone-eye vision anywhere on the surface of Mars where there are enough clear repeat pictures," Professor Jan-Peter Muller from the UCL Mullard Space Science Laboratory said in statement. "It allows us to see objects in much sharper focus from orbit than ever before and the picture quality is comparable to that obtained from landers."

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona).

Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars.

The dark, narrow streaks flowing downhill on Mars at sites such as this portion of Horowitz Crater are inferred to be formed by seasonal flow of water on modern-day Mars. The streaks are roughly the length of a football field.
The imaging and topographical information in this processed view come from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
These dark features on the slopes are called "recurring slope lineae" or RSL. Planetary scientists using observations with the Compact Reconnaissance Imaging Spectrometer on the same orbiter detected hydrated salts on these slopes at Horowitz Crater, corroborating the hypothesis that the streaks are formed by briny liquid water.

Recurring slope lineae (RSL) are active flows on warm Martian slopes that might be caused by seeping water. One of the most active sites known on Mars is in the central peaks (uplifted mountains of deep bedrock) of Hale Crater.
This image shows RSL extending downhill from bedrock cliffs, mostly towards the northwest (upper left). This image was acquired in middle summer when RSL are most active in the southern mid latitudes.
The RSL in Hale have an unusually "reddish" color compared to most RSL, perhaps due to oxidized iron compounds, like rust. Since HiRISE color is shifted to infra-red wavelengths, they are actually especially bright the near-infrared just beyond the range of human vision.

Seasonal frost commonly forms at middle and high latitudes on Mars, much like winter snow on Earth. However, on Mars most frost is carbon dioxide (dry ice) rather than water ice. This frost appears to cause surface activity, including flows in gullies. (Photo via NASA)
The image shows part of the Arabia Terra region, which is scattered with craters of varying sizes and ages. The craters in this image, caused by impacts in Mars’ past, all show different degrees of erosion. Some still have defined outer rims and clear features within them, while others are much smoother and featureless, almost seeming to run into one another or merge with their surroundings.
This color image was taken by Mars Express’s High Resolution Stereo Camera on 19 November 2014, during orbit 13728. The image resolution is about 20 m per pixel.

IN SPACE - SEPTEMBER 2: In this handout image provided by NASA/JPL-Caltech/MSSS, and captured by NASA's Curiosity rover, a rock outcrop called Link pops out from a Martian surface that is elsewhere blanketed by reddish-brown dust, showing evidence for an ancient, flowing stream, September 2, 2012. The fractured Link outcrop has blocks of exposed, clean surfaces. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Water transport is the only process capable of producing the rounded shape of clasts of this size. (Photo by NASA/JPL-Caltech/MSSS via Getty Images)
IN SPACE - AUGUST 8: In this handout image provided by NASA and released on August 8, 2012, the four main pieces of hardware that arrived on Mars with NASA's Curiosity rover are spotted by NASA's Mars Reconnaissance Orbiter (MRO). The High-Resolution Imaging Science Experiment (HiRISE) camera captured this image about 24 hours after landing. The large, reduced-scale image points out the strewn hardware: the heat shield was the first piece to hit the ground, followed by the back shell attached to the parachute, then the rover itself touched down, and finally, after cables were cut, the sky crane flew away to the northwest and crashed. The relatively dark areas in all four spots are from disturbances of the bright dust on Mars, revealing the darker material below the surface dust.

IN SPACE - AUGUST 5: In this handout image provided by NASA/JPL-Caltech/MSSS, This color thumbnail image was obtained by NASA's Curiosity rover during its descent to the surface on Aug. 5 PDT and transmitted to Spaceflight Operations Facility for NASA's Mars Science Laboratory Curiosity rover at Jet Propulsion Laboratory (JPL) in Pasadena, California. The image from Curiosity's Mars Descent Imager illustrates the roughly circular swirls of dust kicked up from the Martian surface by the rocket motor exhaust. At this point, Curiosity is about 70 feet (20 meters) above the surface. This dust cloud was generated when the Curiosity rover was being lowered to the surface while the Sky Crane hovered above. This is the first image of the direct effects of rocket motor plumes on Mars and illustrates the mobility of powder-like dust on the Martian surface. It is among the first color images Curiosity sent back from Mars. The original image from MARDI has been geometrically corrected to look flat. The MSL Rover named Curiosity is equipped with a nuclear-powered lab capable of vaporizing rocks and ingesting soil, measuring habitability, and whether Mars ever had an environment able to support small life forms called microbe.

His colleague, research associate Mr Yu Tao added: "Using novel machine vision methods, information from lower resolution images can be extracted to estimate the best possible true scene. This technique has huge potential to improve our knowledge of a planet's surface from multiple remotely sensed images."
"In the future, we will be able to recreate rover-scale images anywhere on the surface of Mars and other planets from repeat image stacks."
