“Martian workplace experience” : What “special skills” did “Tianwen no.1” practice in one year?
China is the second country in the world to successfully make a soft landing on Mars.On February 10 last year, Tienwen 1 successfully carried out braking and capture, and then entered the orbit around Mars, becoming China’s first man-made Mars satellite and stepping into the “Martian career”.In a blink of an eye, Tianyun-1 has been working on Mars for a year.This year, it has developed a lot of “career skills” on Mars.In an interview with Chinanews.com.cn, Chu Yingzhi, deputy commander of the Tienwon-1 Orbiter at the Eighth Institute of The China Aerospace Science and Technology Corporation, said that the spacecraft has one of the most important features of the spacecraft.There are orbiting spacecraft in the sky and the Zhurong rover on the surface of Mars. The two are working at the same time, so they can compare and reference each other.Other countries’ Mars missions’ change shifts at different times, ‘he said.’ Even if you’re looking at the same place, there may be some changes at different times.The ‘simultaneous detection’ model promises more scientific discoveries.”The orbiter has photographed parts of Mars and is currently in an elliptical orbit, with its closest point about 400 kilometers from the surface and its farthest point 10,000 kilometers from the surface, according to the report.The Zhurong rover traveled about 1.5 kilometers.Chu yingzhi said that the two “simultaneous exploration” mode means that, for example, after the orbiter takes pictures of the whole Planet of Mars, it feels that one spot is found. If the Zhurong rover is not far away, it can drive there and have a look, one “far” and the other “close”, and cooperate to “double observation”.In general, there are two missions for Tianyun-1 to Mars: engineering, mainly to achieve the technical ability to reach Mars, land on Mars and patrol the surface of Mars;In terms of science, China wants to acquire first-hand Martian scientific data, including taking pictures of the planet and exploring the surface material composition, Martian topography and surrounding space environment.The Mars Tianyun-1 probe consists of a orbiter and a landing rover, including the Zhurong rover and an entry module.Surround has been a senior “track change expert”, after many track adjustment.Chu said that after landing on Mars, the orbiter will communicate with the Zhurong rover. There will be a “big antenna” between the orbiter and the Zhurong rover to relay the “curve” of scientific data acquired by the spacecraft back to Earth.But the orbiter didn’t stay in the relay orbit. After completing its phase mission, it was promoted to a remote sensing orbit.Chu said the orbiter currently orbits Mars in about eight hours.In its remote sensing orbit, the Tianyuan-1 orbiter is not only capable of “relay missions” to Zhurong, but also of global coverage of Mars, which means taking pictures of the entire planet.He said that this “global photo” is different from what the public might understand as “turning around and taking a panoramic picture”. The pictures taken by the Tianwen 1 surround camera are shot one by one, and then pieced together one by one. It is necessary to check whether there is any missing place, and if there is any “gap” between the pictures, they have to be reshot.He said there are two resolution cameras on the orbiter, a medium resolution camera that will take pictures of the planet, and a high resolution camera that will take a deeper look at areas of interest to get a fuller, clearer picture.Source: Chinanews.com
