At about 1: 00 a.m. on May 15, the Tianwen -1 probe was de-orbited in its mooring orbit and maneuvered to Mars into orbit. At about 4 o'clock, the landing rover separated from the orbiter. After about 3 hours of flight, it entered the Martian atmosphere. After about 9 minutes of deceleration, hovering, obstacle avoidance and buffering, it successfully soft landed in the pre-selected landing area. After about 30 minutes of separation, the orbiter was lifted and returned to the berthing orbit to provide relay communication for the landing patrol. Subsequently, the "Zhu Rong" rover will carry out global imaging, self-inspection, departure from the landing platform and patrol detection in turn.
my country's first Mars exploration mission was officially approved in 2016. It is planned to achieve Mars orbiting, landing and patrolling through a mission, conduct global and comprehensive orbiting exploration of Mars, and carry out regional patrol exploration on the surface of Mars. The Tianwen 1 probe consists of a orbiting device and a landing patrol device. The landing patrol device includes the "Zhu Rong" rover and the entry module. Since the successful launch of the probe on July 23, 2020, it has completed one deep space maneuver and four midway corrections in the ground fire transfer phase. On February 10, it successfully captured Mars and entered a large elliptical ring fire orbit, becoming China's first artificial Mars satellite. On February 24, 2021, the Tianwen -1 probe successfully implemented the third near-fire braking. After entering the Mars berthing orbit with a cycle of 2 Mars days, it carried out global remote sensing exploration of Mars and conducted a detailed survey of the pre-selected landing area., Detection and analysis of topography, sand and dust weather, etc., to prepare for landing on Mars. During the implementation of the mission, the China National Space Administration has carried out relevant project cooperation with ESA, Argentina, France, Austria and other international space organizations and national space agencies. At present, the probe has been in space for 295 days, about 0.32 billion kilometers from the earth.
Mars exploration is risky and difficult, and the mission faces challenges such as the interplanetary space environment, the thin atmosphere of Mars, the topography of the fire surface, etc. At the same time, it is affected by long distances and long delays, and there are difficulties such as environmental uncertainty, complex landing procedures, and inability to intervene on the ground during the landing phase. The Tianwen -1 mission broke through key technologies such as the second cosmic speed launch, interplanetary flight and measurement and control communication, and exoplanet soft landing, and realized my country's first exoplanet landing. It is another significant development in the development of China's aerospace industry. milestone.
