This past year, the team assessed the return of additional crew on commercial capsules for contingency scenarios and used independent simulation analyses to confirm this capability poses no significant changes in splashdown conditions, thus ensuring additional options for returning crew safely if the primary return vehicle is disabled. Additionally, the NESC is providing key assessments for manual control using a “paper pilot” based on actual pilot responses. This study enabled manual control as a viable survival scenario if the flight computer fails during deorbit, entry, descent, and landing phases of flight. These efforts contributed to an independent verification and validation of commercial providers’ designs that supported certification of commercial flights to and from the ISS. <\/p>\n\n\n\n<p>Standing up a new independent M&S effort in support of the Mars Ascent Vehicle, a critical element delivering Martian soil and atmosphere samples for eventual return to Earth, provides value and increases confidence in the design of this key element for the Mars Sample Return Campaign. The Flight Mechanics team is contributing unique methodologies for studying the challenging dynamics of this two-stage solid motor design where the second stage is unguided and spin-stabilized. <\/p>\n\n\n\n<p><\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-cover \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1780\" height=\"1004\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?w=1780\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1); transform-origin: 43% 13%; object-position: 43% 13%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png 1780w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=300,169 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=768,433 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=1024,578 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=1536,866 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=400,226 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=600,338 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=900,508 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/02\/techup2023-pg48-art3.png?resize=1200,677 1200w\" sizes=\"(max-width: 1780px) 100vw, 1780px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">Frame of Mars ascent vehicle second stage separation dynamics from an M&S animation <\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Independent M&S of key staging and separation events for the SLS has resulted in affirmation of the SLS trajectory and guidance, navigation and control design.
