In caseSchiaparelli ’s crash - landingleft you thinking the European Space Agency ’s ExoMars missionary work was a bust , sleep assure it was n’t . The mission ’s scientific workhorse — its Trace Gas Orbiter ( TGO)—is perform beautifully , as evidenced by the first images and splashes of data ESA has now received back from the Red Planet .
In keeping with ExoMars’goal of learn preindication of lifespan , the TGO ’s agenda is to produce a detailed armory of uncommon accelerator pedal in Mars ’ lower atmosphere . These include water vapour , nitrogen dioxide , acetylene , and most significantly , methane , which is broken apart by sun . If methane is present in Martian air , something — either a biological or geological process — is resupplying it .
The TGO is also fit out with United States Department of State - of - the - art mental imagery equipment . If it does sniff something interesting , ESA will take elaborate photos of the corresponding spot on the aerofoil , so that a succeeding scouter can pay a visit .
Last month , the TGOwas captured by Mars ’ gravityinto a extremely oval-shaped compass . It ’s going to spent the next yr making that range orbitual before the genuine science set out , but in the meanwhile , ESA has plenty of time to examine and calibrate the space vehicle ’s instrument . Thanks to TGO ’s elbow grease over Thanksgiving , ExoMars has now produced its first glance of Mars ’ atmosphere , a couplet of endearing aerial photos and one 3D Reconstruction Period of a airfoil feature , Noctis Labyrinthus , from a pair of stereo images .
It ’s worth noting that because the TGO was just 146 miles ( 235 klick ) above the surface when these images were claim during a late approach , they ’re some of the closest image the orbiter will enamor , menstruation . By this time next twelvemonth , the spacecraft will be home in on its scientific discipline compass , a fix altitude of 250 naut mi ( 400 km ) . Hopefully by that point , ESA will have made the necessary correction to guarantee that the 2020 ExoMars lander does n’t suffer the same destiny as Schiaparelli .
