The two WACs each have a field of view of 38.3°. PanCam and ISEM Calibration Target (PCT) design – Aberystwyth UniversityRadiometric and geometric calibration is overseen by MSSL with involvement from Aberystwyth, Joanneum Research and DLR. The final system component is the Optical Bench, which provides a planetary protection barrier to the external environment (including HEPA filters), as well as mechanical positioning of the PanCam components.
The PanCam science team has developed a detailed science traceability matrix which links the high level goals to instrument performance. The HRC hardware is produced by Kayser-Threde, Munich and DLR Institute for Planetary Research, Berlin, Germany.
The thing has to perfectly work as a whole. Some of the procedures have been tested in the field particularly during the Arctic Mars Analogue Svalbard Expeditions (AMASE) expeditions, as discussed in the next section. PanCam can view the lander top surface and verify mechanism deployments and potentially landing pad interaction with the regolith. TGO’s key goal was to gain a better understanding of methane and other atmospheric gases that could be evidence for possible biological or geological activity. Geologically investigate and map the rover sites including drilling locations. The possible landing sites have been selected with this mission in mind, and they are thought to have the potential for finding well-preserved organic material in them, particularly from the very early history of the planet. But with the slip back to 2020, the Mawrth Vallis and Aram Dorsum locations are once again under consideration. Study the properties of the atmosphere and variable phenomena, including water and dust content of the atmosphere. ExoMars is a joint endeavour between the European Space Agency and Russia's Roscomos agency, and consists of a 2016 Trace Gas Orbiter and Schiaparelli lander, and the 2020 Rover. ExoMars 2020 is the second phase of the ExoMars program (the first, launched in 2016, deployed the ExoMars Trace Gas Orbiter into Mars orbit to map the planet’s atmosphere). It uses RGB on chip filters. In the current ExoMars design, PanCam is the only instrument which can remotely sense the geological context of the landing site, provide detailed 3D terrain models and measure the surface Bidirectional Reflectance Distribution Function (BRDF). The satellite is still orbiting Mars fully operational and its high-gain antenna will be used to support communications between ExoMars 2020 and ground stations on Earth. Like in the previous ExoMars mission, a Russian Proton rocket, formally known as UR-500, has been selected to launch the mission on a, for now, undetermined date in 2020. ESA's ExoMars Trace Gas Orbiter has spotted new gas signatures at Mars.
PanCam arrangement on the rover (schematic). ISEM (Infrared Spectrometer for ExoMars), which will assess the mineralogical composition of surface targets and select suitable samples for further analysis by the other instruments. (b) High Resolution Camera (HRC) for high resolution colour images.
Launch: July 30, 2020, Cape Canaveral Air Force Station, Florida Landing: Feb. 18, 2021 Landing Site: Jezero Crater, Mars Mission Duration: At least one Mars year (about 687 Earth days)
A number of ExoMars-related field trials and tests have been performed in the last few years (see Figure 7), including participation in recent Arctic Mars Analogue Svalbard Expeditions (AMASE) 2008-11. The 83 µrad/pixel scale corresponds to a resolution of 0.17 mmat 2m distance. Exomars 2020 is the second and final mission of the ExoMars programme, the first one being ExoMars 2016. Data flow scenario for ExoMars PanCam radiometric and colourimetric image processing. ExoMars rover – a robotic vehicle – to the planet, with the landing scheduled for 2023. The key new aspect of the mission as a whole is the retrieval and analysis of samples from up to 2m under the oxidised surface of Mars. At each site, to conduct an integral set of measurements at multiple scales: beginning with a panoramic assessment of the geological environment, progressing to smaller-scale investigations on surface outcrops, and culminating with the collection of well-selected subsurface (or surface) samples to be studied in the Rover's analytical laboratory. A pair of Wide Angle Cameras (WACs) and a close-up High Resolution Camera (HRC) provide complementary imaging at different scales. ExoMars 2016 was led by the European Space Agency (ESA) in cooperation with Roscosmos, the Russian space agency, which provided the launch vehicle. Adron, to search for subsurface water and hydrated minerals under the subsurface beneath the rover and therefore select suitable areas for drilling and sample collection. PanCam layout (Credit: MSSL)A summary of the main characteristics of the WACs and HRC is shown in Table 1.Each of the WACs includes 11 filters comprising R,G and B colour bands, a geological filter set (optimised for use on Mars) and atmospheric filters to analyse the water and dust content in the Mars atmosphere. Even at the equator the range is quite extreme: perhaps as "warm" as 0C during the day, but falling to -90C at night. PanCam plays a key role as part of the lander payload in several ways associated with wide angle and high resolution imaging, as mentioned above. To collect scientific samples from different sites, using a rover carrying a drill capable of reaching well into the subsurface and into surface rocky outcrops. The PanCam team need to ensure that electronics and mechanical parts maintain reliable operation throughout a lengthy mission. This is important because due to the little protection that the tenuous Martian atmosphere offers from radiation and photochemistry, the possible organical remainings will have been better preserved under the surface, thus, underground samples are more likely to include biomarkers. Four sites were considered for the ExoMars rover, with the equatorial Oxia Planum site still considered primary for the new launch date. The Optical bench is at the top of the mast, the PCT is at the front of the rover, the FidMs on the top deck and the RIM near the front bogey of the rover.The PanCam calibration target (PCT) is implemented using coloured glass elements similar to ‘stained glass’ with a shadow post for relief. Mechanical configuration of WAC filter wheel and cameras (C.Theobald/MDO, MSSL-UCL). According to current plans, the ExoMars project will comprise four spacecraft: two stationary landers, one orbiter and one rover. In this second endeavour, Roscosmos has taken a step forward as besides providing the launching vehicle they are fully in charge of the landing platform’s and the descent module’s design and of their consequent construction. MSSL is leading the PanCam team to provide the rover's scientific cameras. 2. All mission elements will be sent in two launches using two heavy-lift Proton rockets. Its second part, scheduled for 2022, will send the 300 kg. Together they will address the question of whether life has ever existed on Mars. ExoMars 2020 will deliver a rover and a surface platform to our neighbour planet. These campaigns have been used, in combination with teams from other ExoMars instruments, to develop working procedures representative of a mission to Mars, as well as to test instrument performance, develop calibration techniques and pursue scientific investigations of particular areas.
Mission Name: Mars 2020 Rover Name: Perseverance Main Job: The Perseverance rover will seek signs of ancient life and collect rock and soil samples for possible return to Earth.
The rover is essentially a laboratory on wheels: once collected, a sample is delivered to the rover’s analytical laboratory, here, they are analyzed in-situ with next-generation instruments that should determine the soil composition and identificate the presence of different substances such as minerals, organic substances, and biomarkers.
This simulator includes representative (though not the final) filter wavelengths from which spectral information may be used to study mineralogy. The HRC has a field of view of 5°, and will also return 1024x1024 pixel images. Although we already had figures from previous sketches, we rushed on to create the first available scaled model of the rover’s latest and final design. ExoMars 2020 will deliver a rover and a surface platform to our neighbour planet. The AUPE PanCam simulator at tests in a Hertfordshire, UK quarry and at the AMASE campaign, SvalbardOther PanCam ground tests have included ‘blind’ geological identifications performed in the AU Mars analogue facility, tests in a quarry in Hertfordshire with the Astrium UK ‘Bridget’ prototype rover, tests as part of the SAFER campaign, tests in Iceland in 2013 and 2015, tests in Boulby mine and tests with the Raman team in Staffordshire, UK (2015). Unfortunately, the landing went wrong in the final phase and Schiaparelli crashed into the surface, but the telemetry of the descent was successfully sent and it has helped to improve future landing systems such as the one being used in ExoMars 2020. Ma_MISS (Mars Multispectral Imager for Subsurface Studies) will contribute to the study of the Martian mineralogy and rock formation. The Martian environment presents the main technological challenges facing PanCam. ESA. ExoMars is a joint endeavour between the European Space Agency and Russia's Roscomos agency, and consists of a 2016 Trace Gas Orbiter and Schiaparelli lander, and the 2020 Rover. The rover will collect some of this material with a drill, which is designed to extract samples from various depths, down to a maximum of two meters. Although we already had figures from previous sketches, once the final configuration was confirmed we rushed on to create the first available scaled model of the rover’s latest design. MicrOmega, a visible and infrared imaging spectrometer for mineralogy studies on Martian samples. 2020 ExoMar’s Rover relies on a science payload of nine instruments conceived either for the targeting or analysis of samples: PanCam (The Panoramic Camera), that will perform digital terrain mapping of Mars and look for possible sample’s location. (d) PanCam Optical Bench (OB) to house PanCam and provide planetary and dust protection.
