This is what a recent study presented at the <em>56<sup>th<\/sup> Lunar and Planetary Science Conference<\/em> hopes to address as William O\u2019Hara, who is the Executive Director of Explore Titan investigated what physical attributes a human will experience when standing on Titan\u2019s surface. This study has the potential to help scientists, engineers, mission planners, and the public better understand the risks associated with sending humans to far-off worlds for long periods of time and how to develop technologies to mitigate these risks.<\/p>\n<\/p><\/div>\n<div class=\"youtube-video\">\n<p>\n              <iframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/FFAX2Bhw-dg\" frameborder=\"0\" allowfullscreen=\"\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"><\/iframe>\n            <\/p>\n<\/p><\/div>\n<div class=\"text\">\n<p>For the study, O\u2019Hara used a combination of data evaluation and computer models to simulate what a human would experience standing on the surface of Titan under a variety of conditions, including physical, visual, audio, and scent. As O\u2019Hara notes, this is due to the limited literature, including news articles and scientific studies, regarding sending humans to Titan, including colonization. For context, the surface temperature of Titan is -179 degrees Celsius (-290 degrees Fahrenheit), the surface pressure of Titan is 1.5x Earth&#8217;s surface pressure, and the surface gravity of Titan is just under 14 percent of Earth&#8217;s surface gravity.<\/p>\n<p>In the end, O\u2019Hara concluded that \u201cadditional information\u201d is required to better understand what a human would experience standing on the surface of Titan, including involving lighting and standing at various locations across Titan\u2019s surface. While not mentioned in the study, the surface of Titan only receives approximately 0.1 percent of the light that Earth receives, which accounts for Titan only receiving 1 percent of the light from Earth, with 90 percent of this number being reduced from Titan\u2019s thick and hazy atmosphere.<\/p>\n<\/p><\/div>\n<div class=\"youtube-video\">\n<p>\n              <iframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/ILQ5X97Ak18\" frameborder=\"0\" allowfullscreen=\"\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"><\/iframe>\n            <\/p>\n<\/p><\/div>\n<div class=\"text\">\n<p>For context, this compares to approximately civil twilight on Earth, which occurs about ten minutes after sunset. This is in stark contrast to images sent back by the Huygens probe, which landed on Titan\u2019s surface in January 2005 and showed a bright surface, which was created from various image processing techniques. Therefore, humans would not experience the same lighting as the Huygens probe gave the impression existed on the surface of Titan. <\/p>\n<p>The study notes, \u201cThis study is the first attempt at aggregating what we know about Titan to factually estimate the experience of a human on its surface.\u00a0 The results will inform future work including surface EVA [extravehicular activity] space suit design, habitat design, virtual reality simulations and terrestrial analog exploration. Next steps will be to extract from this work environmental requirements and potential hazards that will need to be addressed.\u201d<\/p>\n<\/p><\/div>\n<div class=\"youtube-video\">\n<p>\n              <iframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/St2JL4tb85Q\" frameborder=\"0\" allowfullscreen=\"\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"><\/iframe>\n            <\/p>\n<\/p><\/div>\n<div class=\"text\">\n<p>This study comes as NASA is preparing to send its Dragonfly quadcopter mission to land on Titan\u2019s surface and \u201chop\u201d across various regions to better understand the habitability potential of Titan, whose diameter is approximately 50 percent larger than Earth\u2019s Moon. Dragonfly is currently slated to launch in July 2028 and land on Titan\u2019s surface in 2034, which will be followed by a science phase that is slated to last approximately 3.3 years. Along with imaging cameras, Dragonfly\u2019s scientific instruments will include a mass spectrometer, gamma-ray spectrometer, neutron spectrometer, and seismometer.<\/p>\n<p>As this study notes, the literature of sending humans to Titan is still limited, possibly due to the current focus involving sending humans back to the Moon and on to Mars. Another reason could be the distance, as spacecraft currently take approximately six years to travel from Earth to Titan, so this would require substantial logistical hurdles to accommodate humans traveling such an enormous amount of distance and time.<\/p>\n<\/p><\/div>\n<div class=\"youtube-video\">\n<p>\n              <iframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/kx4UzkzjERM\" frameborder=\"0\" allowfullscreen=\"\" style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\"><\/iframe>\n            <\/p>\n<\/p><\/div>\n<div class=\"text\">\n<p>The study concludes by stating, \u201cThis work benefits follow on efforts to further mature concepts for human missions deeper into our solar system following NASA\u2019s blueprints.\u201d<\/p>\n<p>What will humans experience when standing on the surface of Titan in the coming years and decades?
