The EXI Hope digital exploration camera used 3 visible spectra, which are “blue, green and red”, in its first working mission after the successful entry into orbit of Mars, through which it has took the first image of Mars, and provided a precise, detailed image of the Red Planet’s atmosphere, in a first hint. Because the camera works efficiently, while the camera is the first of three scientific devices carried by the probe, and that it has indeed started its mission.
High precision
The first image of Mars taken at sunrise, which was characterized with great precision, revealed the “Olympus Society” volcano, which is the largest volcano on Mars and the largest volcano in the solar system.
The image was taken at an altitude of about 25,000 km above the surface of Mars, and in the upper left part of the image appears the North Pole of Mars, and the volcano “Olympus Society” may be seen in the center of the image with the advent of sunlight The image also clearly shows the three volcanoes near the equator on Mars: it is the summit of Ascius, the summit of Pavonis and the summit of ‘Arsia.
The details of the image showed snow clouds over the southern heights (bottom right of the image) as well as around the volcano “Olympus Munis”, which appears at the top left, and the clouds snow clouds are clearly visible (at the top of the image and to the right of the middle) when looking between the planet and the space around it, and the availability of these snow clouds which can be seen in different geographies and at different times of the day is a glimpse of the hopeful probe’s contribution to improving our understanding of the climate on Mars.
Ice gauge
The EXI digital exploration camera also measures ice and ozone in the lower layer of the atmosphere, as the camera is one of the successful innovations designed specifically to achieve the probe’s objectives by studying the atmosphere of the Red Planet, and it is considered a multi-wavelength radiation camera, capable of capturing 12-megapixel images with the maintenance of the radiative gradient required for detailed scientific analysis, and the camera consists of two objectives, one for ultraviolet rays and the other for color spectra, used to capture images with clear Mars detail.
The short focal length of the lens can reduce the time required for exposure to a very short time to capture still images orbiting the planet, and the camera’s sensor consists of a monochrome matrix of 12 megapixel with dimensions of 3: 4, and the image can be captured and stored on the memory chip so that it can be controlled in image size and resolution, which reduces the data transfer rate between the probe and the ground control center.
Important details
The sensor can capture 180 high-resolution images at a time, which means you can shoot 4K movie if needed, and the use of separate filters is an added feature that can provide better accuracy for each color, besides providing more precision details in the image, which helps to reduce the degree of uncertainty when measuring radiation for scientific imaging, and for the ultraviolet lens, the frequency range for short wavelengths would be included between (245-275) nanometers, while the frequency range for long wave would be between (305 – 335) nm, as for the other lens system, this would be a frequency Red color is (625-645) nanometers, the green color is (506-586) nanometers and the blue color is (405- 469) nanometers.
3 devices
The digital camera is one of 3 advanced scientific devices carried by the Hope probe to study Mars, which is the EMIRS infrared spectrometer, which measures the temperature and distribution of dust, water vapor and clouds Of ice in the lower layer of the atmosphere, and the UV spectrophotometer. EMUS, which measures oxygen and carbon monoxide in the Martian thermal layer, and hydrogen and oxygen in the outermost layer of Mars, and these three devices help give a complete picture of Mars’ climate and of its different layers of the atmosphere, which would provide an in-depth understanding of the processes in the atmosphere of the planet Mars.
