b'NASA is foregoing a launch opportunity Tuesday, Sept. 27,\\xa0and preparing for rollback, while continuing to watch the weather forecast associated with Tropical Storm Ian. During a meeting Saturday morning, teams decided to stand down on preparing for the Tuesday launch date to allow them to configure systems for rolling back the Space Launch System rocket and Orion spacecraft to the Vehicle Assembly Building. Engineers deferred a final decision about the roll to Sunday, Sept. 25, to allow for additional data gathering and analysis. If Artemis I managers elect to roll back, it would begin late Sunday night or early Monday morning.\\n\\n\\nEarlier in the week, crews conducted a fuel tanking test to ensure a fuel leak, which scrubbed the first two launch attempts, had been resolved. On Friday, officials talked with reporters about the testing data. That teleconference audio is in this podcast.\\n\\n\\nThe new cryogenic loading procedures and ground automation were designed to transition temperature and pressures slowly during tanking to reduce the likelihood of leaks that could be caused by rapid changes in temperature or pressure. After encountering the leak early in the operation, teams further reduced loading pressures to troubleshoot the issue and proceed with the demonstration test. The pre-pressurization test enabled engineers to calibrate the settings used for conditioning the engines during the terminal count and validate timelines before launch day to reduce schedule risk during the countdown on launch day.\\xa0\\xa0\\n\\n\\n\\n--- \\n\\nSend in a voice message: https://podcasters.spotify.com/pod/show/carolinaweather/message'
