\nExoMars was launched on a Proton-M rocket from Baikonur, Kazakhstan on 14 March 2016. Around seven months later, it arrived at Mars.\n<\/p>\n
\nAs part of preparations for its main science mission to analyse the atmosphere for gases that may be related to biological or geological activity, and image sites that might be related to these sources, the Trace Gas Orbiter has conducted two campaigns to test its science instruments \u2013 one last November and one last week.\n<\/p>\n
\nPresented here is one of the first image pairs taken by the orbiter\u2019s high-resolution camera on 22 November.\n<\/p>\n
\nThe images together form a stereo pair<\/a> of part of the Noctis Labyrinthus<\/a> region of Mars. The camera takes one image looking slightly forwards (bottom image<\/a> in this orientation), and then, after having flown over the area, it rotates to look \u2018back\u2019 to take the second part of the image (top<\/a>), in order to see the same region of the surface from two different angles.\n<\/p>\n \nBy combining the image pair, a 3D image can be constructed and information about the relative heights of the surface features can be seen.\n<\/p>\n \nThe images were taken to test the timing of the images as the spacecraft moves over the surface, in order to best reconstruct the stereo images. Additional tests were conducted last week to fine-tune the process.\n<\/p>\n \nNoctis Labyrinthus, or \u2018Labyrinth of the night\u2019, lies on the western edge of Valles Marineris, the grand canyon of the Solar System, and comprises a vast network of flat-topped plateaus and trenches. Landslides are seen in the flanks of the steep slopes.\n<\/p>\n \nSince arriving, the orbiter has also conducted a number of manoeuvres to change its orbital period and inclination, ready to begin the year-long aerobraking phase later this week. This process will use the planet\u2019s atmosphere to gradually slow the spacecraft speed and so move it into a 400 km near-circular orbit, from which the craft will conduct its main science mission.\n<\/p>\n \nThe images were taken by the CaSSIS<\/a> camera; the scale here is 7.2 m\/pixel and the images correspond to an area on Mars about 15 x 45 km.<\/p>\n","protected":false},"excerpt":{"rendered":" \nExoMars was launched on a Proton-M rocket from Baikonur, Kazakhstan on 14 March 2016.
