Later today we expect to see the Delta IV launch its final mission. About two weeks ago ULA was forced to scrub its last attempt after issues with a pumping system arose in the final minutes of the countdown. A question I’ve seen popping up in a few groups was “Why is ULA retiring the Delta IV?” It’s a valid question, the large capable rocket seems like it should have a long life ahead still but alas, ULA has other plans.
