This creates temperatures high enough to ionize the gas molecules into a hot, dense plasma. To protect against damage, spacecraft are typically covered by a heat shield material that burns in a controlled manner. This process is called ablation. Though current materials are effective for present-day missions, future missions require better heat shields.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2023-01-tokamak-unique-validating-spacecraft-shield.html\" target=\"_blank\" rel=\"nofollow noopener\">Tokamak experiments provide unique data for validating spacecraft heat shield ablation models<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it.
