As shown in the slide below, the spacecraft would release a tethered device that creates a magnetized plasma, which in turn interacts with the atoms in the atmosphere in a manner that creates drag. The size and mass of such a system is much less than for a reentry shield and big parachutes. So it would allow for greater payload mass for missions to Mars or other bodies in the solar system with atmospheres.<\/p>\n<p>Find more details in these resources:<\/p>\n<ul>\n<li><a href=\"http:\/\/www.nasa.gov\/directorates\/spacetech\/niac\/2012_phase_I_fellows_kirtley.html\" target=\"_d\">A Plasma Aerocapture and Entry System for Manned Missions and Planetary Deep Space Orbiters &#8211; NASA<\/a><\/li>\n<li><a href=\"https:\/\/docs.google.com\/file\/d\/0Bx2cC35KJTwsYU5rblJ1UGVWVEk\/edit\" target=\"_d\">Magnetoshells Plasma Aerocapture for Manned Missions and Planetary Deep Space Orbiters, David Kirtley, John Slough, Anthony Pancotti &#8211; NIAC Symposium &#8211; Mar.12.2013 (pdf)<\/a><\/li>\n<\/ul>\n<p><a href=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"2754\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=2754\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell.jpg\" data-orig-size=\"500,379\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"Magnetoshell\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell.jpg\" class=\"aligncenter size-full wp-image-2754\" alt=\"Magnetoshell\" src=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell.jpg\" width=\"500\" height=\"379\" srcset=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell.jpg 500w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2013\/06\/Magnetoshell-300x227.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>NextBigFuture points to a neat concept for slowing a spacecraft when it enters an atmosphere.
