Leon&amp;rsquo;s work looks at how to stop things that do this from melting. It&amp;rsquo;s pretty hard to travel fast enough to melt something unless you drop the object from space and so this problem usually only applies to rockets and re-entry vehicles.&amp;nbsp; Leon discusses some of these challenges and tells us a bit more about orbital travel.","author_name":"Verge of Discovery","author_url":"http:\/\/www.VergeofDiscovery.com\/","html":"<iframe title=\"Libsyn Player\" style=\"border: none\" src=\"\/\/html5-player.libsyn.com\/embed\/episode\/id\/4133826\/height\/90\/theme\/custom\/thumbnail\/yes\/direction\/forward\/render-playlist\/no\/custom-color\/88AA3C\/\" height=\"90\" width=\"600\" scrolling=\"no\"  allowfullscreen webkitallowfullscreen mozallowfullscreen oallowfullscreen msallowfullscreen><\/iframe>","thumbnail_url":"https:\/\/assets.libsyn.com\/secure\/item\/4133826"}
