However image captured, C/2013 A1 was 8.5 million km (5.3 million miles) away. 3I/ATLAS's close approach to Mars, it much further, @28 million km (18 million miles) from the Mars Planet. European Space Agency says its Mars Express & ExoMars Trace Gas Orbiter (TGO) spacecraft will observe 3I/ATLAS on 3 October 2025, around the time of comet's closest approach to Mars Instruments on these spacecraft include Mars Express’s High Resolution Stereo Camera (HRSC) and ExoMars TGO’s Colour & Stereo Surface Imaging System (CaSSIS), cameras used primarily to photograph Mars Red Planet, but may be turned towards 3I/ATLAS to capture views of the comet from another world. ESA they'll attempt to measure spectrum of light from comet use Mars Express’s OMEGA & SPICAM spectrometers and TGO’s NOMAD spectrometer. These instruments will be able to study light from the 3i thereby reveal more about the comet's composition chemical makeup. ESA says 3I/ATLAS would only take up less than a pixel in images captured by Mars Express and the ExoMars Trace Gas Orbiter. "We expect better images of halo of gas around. So perhaps shouldn't expect anything spectacular, image-wise missions, instead science that astronomers can delve into...
