Trzecia partia danych uzyskanych przez misję #Tianwen -1 została upubliczniona！ Dane te zostały zebrane przez 12 ładunków naukowych na pokładzie Tianwen-1 w grudniu 2021 r. Entuzjasta astronomii przetworzył dane i udostępnił nam niesamowite zdjęcia.

Bardzo spektakularne zdjęcie z orbity Marsa. Wspaniale pokazana Valles Marineris.

Zdjęcia Tianwen 1 posłużyły do stworzeni najdokładniejszej, kolorowej mapy Marsa:

A new high-resolution global color image dataset of Mars has been released, thanks to data gathered by China's Tianwen-1 mission. This dataset is a significant advancement for Mars exploration, offering unprecedented detail and accuracy for global color images of the Martian surface.

The Tianwen-1 mission, which began capturing data on July 25, 2022, has dramatically improved the situation. The mission's Moderate Resolution Imaging Camera (MoRIC) completed 284 orbits during its remote-sensing phase, capturing 14,757 images with resolutions between 57 and 197 meters. These images achieved comprehensive coverage of Mars. Additionally, the Mars Mineralogical Spectrometer (MMS) aboard Tianwen-1 collected 325 strips of data in the visible and near-infrared bands, with resolutions ranging from 265 to 800 meters.

Under the leadership of Professor Li Chunlai from the National Astronomical Observatory of the Chinese Academy of Sciences and Professor Zhang Rongqiao from the Lunar Exploration and Space Engineering Center, the Tianwen-1  science team, along with collaborators, processed the image data to produce a global map of Mars. This involved using bundle adjustment technology to optimize the original orbit measurement data by treating Mars as a unified adjustment network. The position deviation between individual MoRIC images was reduced to less than 1 pixel, resulting in a pixel-level "seamless" global image mosaic. The team ensured brightness and color consistency through color correction, creating a true-color reference for the Martian surface.

The result of this extensive effort is the Tianwen-1 Mars Global Color Orthomosaic 76 m v1, a global color image dataset with a resolution of 76 meters and a horizontal accuracy of 68 meters. This dataset represents the highest resolution true-color image map of Mars available to date, filling the gap in high-precision global color-image data at this scale. The new mapping product is expected to serve as a superior geographic reference for future Mars exploration missions and scientific studies, providing an essential tool for global mapping at scales of tens of meters, meters, and submeters.
