摘要：

First, the technical characteristics and difficulties in system design and ground verification are analyzed, considering the particularity of the mission type and the working environment in the process of Mars entry, descent, and landing (EDL). The system composition and main configuration involved in the Tianwen-1 probe’s EDL are then introduced. The EDL stage’s design schemes (including flight before atmosphere entry, aerodynamic deceleration, parachute deceleration, power deceleration, and landing buffer) and the selection process of the landing sites, ground simulations, and test verification conditions are discussed. Finally, the actual in-flight results are presented, and the effectiveness of the system design is verified. © 2022 Chinese Academy of Sciences. All rights reserved.
