A\u00a0NASA\u00a0scientific balloon carrying a next-generation space science instrument has successfully launched over Antarctica, continuing a legacy of discovery that began at the University of\u00a0Hawai\u02bbi\u00a0at M\u0101noa.<\/p>\n
The mission, known as the Payload for Ultrahigh Energy Observations, or\u00a0PUEO, lifted off Dec. 20 (Dec. 19, Eastern Standard Time), from\u00a0NASA\u2019s launch facility near McMurdo Station. The balloon reached an altitude of about 120,000 feet and is now drifting high above the Antarctic ice while collecting data.<\/p>\n

PUEO\u00a0is designed to study tiny particles called neutrinos that travel through space at extremely high energies. When these particles strike the thick Antarctic ice, they create brief radio signals. From its vantage point far above the surface, the balloon-mounted instrument listens for those signals, using the ice below as a natural detector.<\/p>\n

By tracking these signals, scientists hope to learn more about powerful events in the universe, such as black hole formation and collisions between dense stars. The mission also includes two additional balloons that send test signals to help researchers confirm the instrument is working properly.\u00a0PUEO\u00a0is expected to remain airborne for several weeks, circling the continent as it gathers information.<\/p>\n
\u201cThis mission shows how ideas that start in\u00a0Hawai\u02bbi\u00a0can grow through years of collaboration and dedication into discoveries that help answer some of the biggest questions about our universe,\u201d\u00a0Department of Physics and Astronomy<\/a>\u00a0Professor Peter Gorham said. \u201cIt reflects the creativity and persistence of our students, researchers and engineers, and it points to a future where\u00a0UH\u00a0research continues to play a meaningful role in advancing science worldwide.\u201d<\/p>\n PUEO\u00a0builds on earlier work led by\u00a0UH\u00a0researchers through the\u00a0Antarctic Impulsive Transient Antenna<\/a>. That earlier project completed four balloon flights between 2006 and 2016 and helped open a new way of studying high-energy particles using radio signals detected over Antarctica.\u00a0ANITA\u00a0also recorded unusual particle events that scientists are still working to understand. With improved sensitivity and updated technology, PUEO aims to expand on those discoveries and clarify unanswered questions from the earlier missions.<\/p>\n ARTICLE CONTINUES BELOW AD<\/p>\n This is the second high-altitude scientific balloon launched from Antarctica this season with major\u00a0UH\u00a0involvement. On Dec. 15, a separate scientific balloon carried the\u00a0General AntiParticle Spectrometer experiment<\/a>\u00a0into the sky to search for rare cosmic antimatter linked to dark matter. Together, the missions highlight\u00a0UH\u2019s growing role in\u00a0NASA-led balloon research, using Antarctica\u2019s unique environment to study some of the most basic questions about the universe.<\/p>\n ARTICLE CONTINUES BELOW ADARTICLE CONTINUES BELOW AD<\/p>\n
