The MIR and NIR channels follow on from TIMM-2 (Phobos-Grunt), Rusalka (ISS) and SOIR (Venus Express). A high resolution camera (5 metres per pixel) capable of obtaining colour and stereo images over a wide swathe. The ExoMars trace gas orbiter is designed to search for methane and other minor constituents of the Martian atmosphere on a global scale. Trace Gas Orbiter - Ultime notizie su Trace Gas Orbiter - Argomenti del Sole 24 Ore. Ultime notizie: Trace Gas Orbiter. CaSSIS characterises sites that have been identified as potential sources of trace gases and investigates dynamic surface processes – for example, sublimation, erosional processes and volcanism – which may contribute to the atmospheric gas inventory. Una lunga frenata attraverso l'atmosfera di Marte, con il cosiddetto aerobraking, ha messo la sonda ExoMars 2016 in orbita stabile e operativa: ora si comincia a cercare indizi di vita. The ExoMars Trace Gas Orbiter (TGO or ExoMars Orbiter) is a collaborative project between the European Space Agency (ESA) and Roscosmos that sent an atmospheric research orbiter and the Schiaparelli demonstration lander to Mars in 2016 as part of the European-led ExoMars programme. This measured hydrogen content can be related to the presence of water. The inclination of the TGO's orbital plane has been chosen to optimise the science that can be done with the instrument suite. This includes mapping the distribution of trace gases, identifying their sources and sinks, and studying geographical and temporal variability. This rotation system also enables the camera to acquire stereo images with only one telescope and focal plane assembly. Agrodolce. The orbiter science payload is primarily nadir pointing to keep the Martian surface in constant view. Another important objective is to image and to characterise features on the Martian surface which may be related to trace gas sources. Artist's impression of the Trace Gas Orbiter showing where the science instruments are located. The Trace Gas Orbiter carries scientific instruments for the detection of trace gases with an improved accuracy - 1000 times better - compared to previous measurements from orbit and ground-based measurements. The distribution of neutron velocities, which depends upon how much they were slowed down before escaping, can reveal much about the surface material since it depends on the composition of that material – primarily on its hydrogen content. La Divisione Sistemi Avionici e Spaziali di Finmeccanica fornisce invece sistemi fotovoltaici, unità di potenza e sensori di assetto e contribuisce alla realizzazione dello strumento CaSSIS. Facebook looking directly at the sunlight reflected from the surface and atmosphere of Mars. Mapping of the deuterium/hydrogen ratio (D/H) will also be performed, to provide new information on water reservoirs and atmospheric escape. Gli strumenti di ExoMars non confermano le misure di Mars Express e Curiosity: non c'è metano nell'atmosfera del Pianeta Rosso. It is also providing new data for the study of the temporal and spatial evolution of trace gases in the Martian atmosphere, and for the location of their source regions. The ExoMars Trace Gas Orbiter is an ESA and Roscosmos mission to Mars. The data assimilation technique adopted by the science team will allow them to model the atmospheric circulation. Atmosfera di Marte: c'è o non c'è metano? The joint ESA-Roscosmos ExoMars Trace Gas Orbiter, or TGO, arrived at the Red Planet in October 2016, and spent more than one year using the aerobraking technique needed to reach its two-hour science orbit, 400 km above the surface of Mars. This neutron detector can map hydrogen on the surface down to a metre deep, revealing deposits of water-ice near the surface. The team studied the atmosphere from this angle many times for more than seven months, scanning different altitudes between 20 and 400 km (12.4 and 248.5 mi) above the surface twice every four-day orbit. The ExoMars Trace Gas Orbiter (TGO) has detected a tinge of green in the atmosphere, making it …
