Design and Validation of the Scientific Data Products for China’s Tianwen-1 Mission [PDF]
Space Science Reviews, 2021 AbstractThe Tianwen-1 mission is China’s first Mars exploration mission. To complete the scientific objectives of “orbiting, landing, and patrolling” in one mission, thirteen instruments for acquiring multi-disciplinary data are configured. The data products with rich ancillary data and flexible structures will facilitate the data application.

Powered-descent landing GNC system design and flight results for Tianwen-1 mission [PDF]
Astrodynamics, 2022 AbstractThe powered-descent landing (PDL) phase of the Tianwen-1 mission began with composite backshell—parachute (CBP) separation and ended with landing-rover touchdown. The main tasks of this phase were to reduce the velocity of the lander, perform the avoidance maneuver, and guarantee a soft touchdown.
