Down! It's done! Fire! BIT "Wisdom" set foot on Mars!
On May 15th,
The first Mars exploration mission of China-
Landed in a pre-selected landing area
In the southern Mars Utopia Plain
Left a Chinese mark on Mars for the first time
Taking an important step in China’s interstellar exploration journey
In the follow-up,
The Zhurong Mars rover will carry out
Global imaging self-inspection of the landing site
And leave the landing platform
To carry out inspections
Congratulations to Tianwen-1 for successfully landing on Mars!
"Tianwen-1" Knowledge Card
The "Tianwen-1" mission is the first step for
China to independently carry out interplanetary exploration.
To achieve “circumnavigation, landing, and patrol” of Mars through a single launch, that is, Mars circumnavigation, Mars landing, and Mars surface patrol.
Detailed flight mission
The whole process of the mission from Earth to Mars
Can be divided into six steps
The editor will take you to find out as follows!
Six steps for a mission from Earth to Mars
Earth-Mars transfer section
Mars orbital section
Mars mooring section
Off-orbit landing section
Scientific exploration section
The total weight of "Tianwen-1" is about 5 tons
Composed of orbiter and landing patrol
The landing patrol mainly includes entry module and Mars rover

In the morning of April 24
National Space Administration officially announced
The first Mars rover of China is named "Zhu Rong"
The full name is "Zhurong"
The first Mars exploration engineering probe of China
There are 13 kinds of payloads in total
Among them, 7 types of orbiters and 6 types of Mars rover
The first Mars exploration mission will
Collect important data such as the space environment and morphological characteristics, surface structure and atmospheric environment of Mars

Professor Xia Yuanqing
Guesting on CCTV's "Dialogue" program
The long journey of seeking scientific truth
The pursuit of technological innovation is endless
Behind the smooth landing of "Tianwen-1"
Are people from BIT escorting it!
A comprehensive simulation system for Mars precision landing navigation and guidance control was developed. The results have been applied to the project demonstration design and development of the "Tianwen-1" Mars lander autonomous navigation and guidance control system, and the Mars orbiter autonomous management and navigation control system.
Through the establishment of dynamics and kinematics models of the Mars rover, the problem of communication "black barriers" was analyzed, and the navigation scheme and guidance control scheme were designed to solve the problem of optimal energy consumption during the power descent phase and the problem of visual navigation during the landing phase. The research results provide a theoretical reference for the landing process of the Mars rover.
BIT people participated in the entry process aerodynamic thermal load analysis project of the landing patrol vehicle. The project results were used to predict the dynamic environment of vehicle landing process of the Mars landing patrol, which provided a design basis for the formulation of the entire vehicle's environmental conditions.
BIT people undertook the simulation analysis of the design verification of the pyrotechnic lock of the two-cabin connection unlocking mechanism of Tianwen-1 and the space life verification of the pyrotechnic agent, analyzed the low-temperature failure mechanism of the pyrotechnic lock design process, and the research was successfully implemented for the unlocking task of the pyrotechnic lock, providing technical guarantee.
From teachers and students to alumni
From school to the front line of retributing the country to the sky
Generations of BIT people
Become a forerunner and leader of aerospace power
For the smooth landing of "Tianwen-1"
And make outstanding contributions
The universe is vast, the stars are shining
Forge ahead, chase dreams in the universe
People of BIT
With a rigorous and scientific attitude and
The courage to be self-reliant
Bravely innovating "no man's land"
Struggle unremittingly on the road of "expanding the sky
Demonstrating the grandeur and great ambition, make new achievements!
