This area was also used for follow-up searches for the lander after the initial identification (see §2.1.).

Location of the proposed Beagle 2 lander candidate. The entry, descent and landing (EDL) design was based on concepts developed for the Huygens parachute landing on Titan and NASA's Pathfinder and Mars Exploration Rovers (MERs), with adaptations and design changes as needed for Beagle 2 and MEX. This ellipse had an area of 14 500 km 2 posing a considerable challenge to any attempt to locate the lander and associated hardware. The 3-sigma landing ellipse size at the time of launch was 174 × 106 km with a 74.9° azimuth. The original, planned landing site in Isidis Planitia at 11.60° areocentric north latitude, 90.74° eastward longitude and –3367 m MOLA elevation (figures 1 and and2) 2) was described in. GAP was also designed to search for methane within the atmosphere as a potential biomarker and science objectives included attempting in situ K-Ar age dating of samples. It was also designed to study the inorganic chemistry and mineralogy of the landing site with its other instruments and take multispectral imagery with PanCam. Sub-surface samples would have been obtained using the so-called ‘mole’, a hammering self-burying penetrometer-type mechanism. 2 m) the surface using the gas analysis package (GAP) mass spectrometer and a stepped combustion-based system. 33 kg) was designed to search for extinct life via isotopically fractionated organic material on and below (approx. Beagle 2 was Europe's first Mars lander project.

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.īeagle 2 was the small (72.7 kg including entry and landing systems) UK-led probe which was part of European Space Agency's (ESA's) Mars Express (MEX) mission launched on 2 June 2003. 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. 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. 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. 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 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. 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 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.
