The launch of a United Launch Alliance Atlas V carrying the SBIRS GEO Flight 5 mission for the U.S. Space Force’s Space and Missile Systems Center (SMC) has been scrubbed.

During Centaur liquid oxygen (LOX) chilldown operations, the team identified an anomalous system response that could not be resolved within the launch window.

Launch is now scheduled for 1:31 p.m. EDT on Tues., May 18, 2021.
