Additionally, the Artemis program plans to construct a residential area on the lunar surface, where crews will stay for long durations. In these environments with different gravity levels from Earth (0G in orbit and 1\/6G on the lunar surface), research is being conducted to understand how solid materials burn to ensure fire safety during long-term manned space activities. The photo shows the result of a combustion experiment on filter paper conducted using the Solid Combustion Experiment Module (SCEM) on the ISS. Ignition starts from the far right, and a unique phenomenon of microgravity is observed, where the flame becomes round and meanders as it spreads. By understanding the conditions under which fire spreads, we can establish fire safety policies.<\/p>\r\n<p>&nbsp;<\/p>\r\n<section class=\"e-separate e-object\">\r\n<div class=\"e-separate-item e-separate-half\">\r\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1-1024x482.jpeg\" alt=\"\" width=\"1024\" height=\"482\" class=\"aligncenter wp-image-116 size-large\" srcset=\"https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1-1024x482.jpeg 1024w, https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1-300x141.jpeg 300w, https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1-768x362.jpeg 768w, https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1-1536x723.jpeg 1536w, https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image1.jpeg 1920w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/p>\r\n<p>A flame spreading over a filter paper in a moderate opposed flow within SCEM on the ISS\/Kibo<\/p>\r\n<\/div>\r\n<div class=\"e-separate-item e-separate-half\">\r\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image2-e1709696020327.jpg\" alt=\"\" width=\"548\" height=\"400\" class=\"aligncenter wp-image-115 size-full\" srcset=\"https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image2-e1709696020327.jpg 548w, https:\/\/c-srup.eng.gifu-u.ac.jp\/en\/wp\/wp-content\/uploads\/2024\/01\/image2-e1709696020327-300x219.jpg 300w\" sizes=\"auto, (max-width: 548px) 100vw, 548px\" \/><\/p>\r\n<p>A trace of the pyrolysis zone captured by an infrared camera at the near-flammability limit<\/p>\r\n<\/div>\r\n<\/section>","protected":false},"featured_media":115,"parent":0,"menu_order":2,"template":"","class_list":["post-43","research","type-research","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"<title>Spacecraft Fire Safety \u2500What Are the Fire Safety Standards in Different Gravitational Environments?\u2500 -
