Tianwen Road

At the beginning of the Sui Dynasty, who preached? Since there was no form up and down, why should we investigate it? "-" Tianwen ". On April 24, 2020, China's planetary exploration mission was officially named "Tianwen", and the first Mars exploration mission was named "Tianwen-1". The Tianwen-1 mission has unprecedentedly achieved the three major tasks of "circling", "landing", and "patrolling" in one go. The Tianwen-1 probe consists of an orbiter, lander, and rover. It was launched by the Long March 5 Y-4 carrier rocket from the Wenchang Space Launch Site on July 23, 2020, and arrived near Mars in February 2021 for Mars capture. After three months of orbiting exploration, the lander separated from the orbiter and successfully landed on the surface of Mars on May 15.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Mars brake capture refers to the process by which a probe, when approaching Mars, ignites its main engine for a long time, causing the probe to decelerate rapidly in interplanetary space, allowing it to be captured by the Martian gravitational field and enter a fire orbit. The biggest challenge of this mission is the high delay in telemetry signals. The entire landing on Mars actually relies heavily on Tianwen-1 to handle it on its own, and the Earth's measurement and control stations find it difficult to real-time monitor the status of Tianwen-1, landing module, Mars rover, and lander during each stage of landing.
