The U.S. Space Force’s 45th Weather Squadron predicts a 90% chance of favorable weather during tomorrow’s launch of NASA’s IMAP (Interstellar Mapping and Acceleration Probe) mission. The primary weather concern is the cumulus cloud rule.

SpaceX’s Falcon 9 rocket will launch NASA’s IMAP and its two rideshares no earlier than 7:30 a.m. EDT Wednesday, Sept. 24, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

NASA’s live IMAP blog coverage begins at 6 a.m. EDT Wednesday. Launch coverage begins at 6:40 a.m. EDT on NASA+, Amazon Prime, the agency’s website, and the agency’s YouTube Channel. NASA’s Spanish launch coverage also begins at 6:40 a.m. EDT on NASA+, and the agency’s Spanish-language YouTube channel.
