Predicting the degree of degradation of space debris is therefore of great concern for space<br>agencies such as ESA and NASA in order to mitigate population risks and environmental concerns.<br>With the great concern, the analysis of the re-entry space debris and the estimation of the on-ground<br>risk are becoming important topics in space science. In this paper, analysis of post shock relaxation<br>data and by-products generation has been conducted. The results have shown that there are large<br>differences in between equilibrium post shock assumptions and non-equilibrium assumptions at high<br>altitudes. The non-equilibrium effects are strong at high altitudes, and consequently the equilibrium<br>flow underestimates the flow temperatures as well as dissociated atoms, resulting in a difference in<br>by-products generation, implying the importance of considering the non-equilibrium flow effects on the<br>re-entry analysis.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-401.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Seong-Hyeon Park, Javier Navarro Laboulais, P\u00e9n\u00e9lope Leyland, Stefano Mischler<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-0401<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1006],"tags":[1289,1290,1291,1192],"class_list":["post-16386","post","type-post","status-publish","format-standard","hentry","category-hisst-2022","tag-by-products","tag-non-equilibrium","tag-post-shock","tag-space-debris","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16386","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16386"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16386\/revisions"}],"predecessor-version":[{"id":16388,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16386\/revisions\/16388"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16386"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16386"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16386"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
