The Tianwen-1 Mars entry capsule successfully landed on the surface of Mars in southern Utopia planitia on May 14th, 2021 at 23:18 UTC. One of the biggest challenges it faced is that a typical blunt body such as the capsule suffers dynamic instability in during supersonic travel. Investigating the unstable Mach range of flight and confirming the design of the lander's aerodynamic shape and mass properties was key to achieve the Mars entry.
