The images released this time are in color, including orthographic projections of the eastern and western hemispheres of Mars, Robinson projection, and Mercator projection plus azimuth projection made in accordance with mapping standards, with a spatial resolution of 76 meters. it will provide a better quality base map for Mars exploration engineering and Mars scientific research.

The medium-resolution camera of the Tianmen-1 mission orbiter carried out 284 remote sensing images from November 2021 to July 2022, achieving global coverage of the Martian surface. The ground application system processes the 14757 image data to get the global color image of Mars.

The Chinese logo will be permanently engraved on the land of Mars.

The distribution map of ▲ 's 22 geographical entities has been published in authoritative domestic and foreign academic journals such as Nature (Nature), Nature-Astronomy (Nature Astronomy), Nature-Earth Science (Nature Geoscience), Science Progress (Science Advances) and National Science Review.

As previously reported by CTOnews.com, the Tianmen-1 probe was successfully launched on July 23, 2020, and successfully entered the orbit of the encirclement fire after a 202-day flight. On May 15, 2021, the landing patrol landed at the target landing site. I wish the Rong rover to carry out patrol exploration.

The National Space Administration News and publicity Center said that the first Mars exploration mission was successfully completed to orbit, land and patrol Mars in one step. The 13 payloads carried by the mission accumulated the original scientific data 1800GB, forming a standard data product.
