\nMars Express, ESA\u2019s deep-space probe orbiting the Red Planet, carries a Visual Monitoring Camera that originally provided simple, low-resolution photos of the separation of the Beagle lander. It was then switched off, its prime assignment fulfilled.\n<\/p>\n
\nIn 2007, it was recommissioned as the \u2018Mars Webcam\u2019 and has since then provided a wealth of Mars images \u2013 including whole-planet views and images of the Mars crescent and limb not otherwise obtainable.\n<\/p>\n
\nImaging slots are scheduled on a time-available basis so as not to interfere with the probe\u2019s scientific instruments, and image sets are delivered only after science data have been downloaded.\n<\/p>\n
\nLinks to new image sets are automatically posted via Twitter (@esamarswebcam<\/a>) and Flickr<\/a>.\n<\/p>\n \nThe camera was off for several months during the recent eclipse season, when Mars Express passes through the planet\u2019s shadow during part of each orbit. This reduces the overall power available on board the spacecraft, meaning the camera can\u2019t be used.\n<\/p>\n \nHowever, it returned to action this week, delivering a set of 10 images<\/a> on Tuesday, which were acquired around 18:00 GMT the previous evening.\n<\/p>\n \nThe image above is a \u2018stack\u2019 created by amateur photographer Dylan O\u2019Donnell, in Australia. He used nine of the 10 to build a composite that removes some of the noise, blemishes and artefacts inherent to the native images.\n<\/p>\n \nVMC images have become very popular with amateur astronomers, photographers, planetologists and Mars enthusiasts<\/a>, who have used them to create artistic reworks and even to conduct scientific analysis of martian clouds, atmosphere and surface features.\n<\/p>\n \nIn 2015, ESA\u2019s international #VMCSchools campaign<\/a> invited students and youth groups to submit observation proposals, identifying the martian feature they wished to image in a scientific or artistic project. Proposals were accepted from Europe, the US, Argentina and Australia.\n<\/p>\n \nMore information<\/b>\n<\/p>\n \nhttp:\/\/blogs.esa.int\/vmc<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" \nMars Express, ESA’s deep-space probe orbiting the Red Planet, carries a Visual Monitoring Camera that originally provided simple, low-resolution photos of the separation of the Beagle lander.
