This launch was supposed to happen on Dec 9, but the launch was scrubbed at T minus 7 seconds, even as fires burned beneath the rocket (a normal procedure to burn off excess hydrogen). Scrubbed again on Dec 18, Dec 19 (due to "elevated hydrogen levels within the port booster engine section"), and Dec 20. Delayed from Dec 30, Jan 6. The largest of the Delta 4 family, the Heavy version features three Common Booster Cores mounted together to form a triple-body rocket.
