However, from a scientific perspective, the concern amounts from the cosmic disruption for researchers and others in the space industry.<\/p>\n<p>&#8220;With the advent of more affordable launch options large-scale commercial use of space has become a reality,\u201d explained Siegfried Eggl, co-lead of the study, and faculty member in the Department of Aerospace Engineering at the <a href=\"https:\/\/illinois.edu\/\" target=\"_blank\" rel=\"noopener\">University of Illinois Urbana-Champaign<\/a>. \u201cAs with so many ambitious projects, the increased presence of tens of thousands of artificial satellites in low-<a href=\"https:\/\/www.innovationnewsnetwork.com\/scientists-investigate-last-terra-incognita-earths-surface\/17881\/\">Earth<\/a> orbit comes with challenges.<\/p>\n<p>\u201cFor example, sunlight reflected off solar sails causes satellites to be bright enough to be visible with the naked eye. At times, those satellites are brighter than most stars on the sky. Because they are also fast moving, they pose a significant challenge to ground-based astronomy, but they may also affect wildlife relying on a starry sky to navigate.\u201d<\/p>\n<h3>What benefits are anticipated from the new centre?<\/h3>\n<p>The intention for the new centre is to bring all stakeholders together, so that practical solutions can be proposed and employed, inevitably minimising the potential adverse impacts of \u2018mega-constellations.\u2019<\/p>\n<p>\u201cUIUC is one of the main contributors to the new centre,\u201d Eggl added. \u201cThis speaks to the trust the international community puts in us to create links between aerospace industry, astronomers, regulators, and other stake holders.\u201d<\/p>\n<p>Eggl will coordinate the UIUC\u2019s attempted propositions for the centre and develop software that can help to better understand the impact of satellite mega-constellations on large astronomical surveys, such as, the upcoming \u2018Legacy Survey of Space and Time\u2019 conducted at the Vera C. Rubin Observatory.<\/p>\n<p>\u201cIn particular, I will study how constellations affect our ability to spot potentially hazardous asteroids and work with aerospace industry to mitigate any potentially negative effects to the largest possible extent,\u201d Eggl commented.<\/p>\n<p>\u201cThis astronomical survey ended just as the satellite constellations began to grow in earnest,\u201d concluded Robert Gruendl, co-lead, and production scientist for the Dark Energy Survey at NCSA. \u201cThe camera used for that survey, DECam, continues to operate at the Cerro Tololo Inter-American Observatory in Chile. We can use the infrastructure developed for the Dark Energy Survey to monitor the impact as the satellite constellations grow and to test strategies for mitigating their impact.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A research team has established a new International Astronomical Union Centre to protect the dark sky from satellite constellation interference.
