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&#8217;s aerodynamic shape and mass properties was key to achieve the Mars entry. In a research paper recently published in Space: Science &amp; Technology, Haogong Wei from the Beijing Institute of Spacecraft System Engineering conducted a ballistic range test to capture the supersonic dynamic characteristics of Tianwen-1.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2022-01-scientists-supersonic-dynamic-characteristics-tianwen-.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">How scientists tested the supersonic dynamic characteristics of the Tianwen-1 Mars Entry Capsule<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>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.
