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.
