One instrument named BioSensor, an autonomous fluidic-based system developed and built at NASA Ames, is based on the BioSentinel CubeSat. The BioSensor contains 16 microfluidic cards that house dry yeast cells in tiny compartments. Once LEIA arrives on the Moon, NASA scientists will direct BioSensor to release a liquid with nutrients that will cause the yeast to grow \u2013 like the process of blooming yeast when baking at home. The BioSensor will then measure the growth and metabolic activity of the yeast using a three-color LED detection system and a dye that provides a readout of yeast cell activity. Changes in cell activity may indicate radiation damage.<\/p>\n\n\n\n<p>The two other LEIA instruments are radiation detectors that will measure the yeast\u2019s radiation exposure and collect detailed measurements of radiation levels on the lunar surface \u2013 an important contribution to risk assessments for future crewed missions. <\/p>\n\n\n\n<p>The Airborne Radiological Enhanced-sensor System (ARES) linear energy transfer (LET) spectrometer is a charged particle detector and is similar to the LET instrument currently <a href=\"https:\/\/www.nasa.gov\/image-feature\/ames\/nasa-extends-biosentinels-mission-to-measure-deep-space-radiation\">taking measurements aboard BioSentinel<\/a>. <\/p>\n\n\n\n<p>The Miniature Fast Neutron Detector (Mini-FND) detects neutral particles \u2013 called neutrons \u2013 and was specifically chosen for LEIA because it measures a type of space radiation that hits and is reflected by the lunar surface but cannot be detected by the ARES instrument. <\/p>\n\n\n\n<p>LEIA is scheduled to land in the South Pole region of the Moon in 2026. It is currently scheduled to be the first biology payload delivered through NASA\u2019s CLPS initiative. <\/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\/2023\/08\/acd23-0020-035-1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"2048\" height=\"1534\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?w=2048\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"\" style=\"transform: scale(1.2); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg 7348w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=300,225 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=768,575 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=1024,767 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=1536,1151 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=2048,1534 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=400,300 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=600,449 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=900,674 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=1200,899 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/08\/acd23-0020-035-1.jpg?resize=2000,1498 2000w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">A pair of Lunar Explorer Instrument for space biology Applications, LEIA, manifold-mounted microfluidic cards being filled with growth medium containing blue dye at NASA\u2019s Ames Research Center in California\u2019s Silicon Valley.<\/div><div class=\"hds-credits\">NASA\/Dominic Hart<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p><strong>Milestones<\/strong><\/p>\n\n\n\n<ul>\n<li>September 2021: The LEIA project selected two NASA Ames-based teams, led by principal investigators Andrew Mark Settles and Sergio Santa Maria, to develop the yeast experiments.<\/li>\n\n\n\n<li>June 2022: The LEIA suite, including BioSensor, ARES, Mini-FND, and the biology experiments, was selected for delivery to the lunar surface through the CLPS initiative.<\/li>\n<\/ul>\n\n\n\n<p><strong>Collaborators<\/strong><\/p>\n\n\n\n<ul>\n<li>NASA Ames manages the LEIA mission and leads the mission’s science, systems engineering, and operations. <\/li>\n\n\n\n<li>NASA\u2019s Johnson Space Center in Houston provides the ARES LET spectrometer.<\/li>\n\n\n\n<li>The Southwest Research Institute in Boulder, Colorado, is developing and providing the Mini-FND.
