Dec. 6, 10:30 a.m. EST: During tanking, two of four LH2 Engine Cutoff (ECO) sensors failed to respond appropriately, which is a Launch Commit Violation. The requirement to proceed calls for 3 of 4. The launch was scrubbed at 9:56 a.m. EST on the recommendation of Launch Director Doug Lyons.

Mission Management Team Chairman LeRoy Cain concurred following a short briefing on the issue. The ice inspection team will proceed with an abbreviated vehicle inspection prior to offloading the LO2 and LH2 and recycle for a launch attempt tomorrow, at 4:09 p.m.
