Ares was a boondoggle design forced on the engineers by management trying to maximize political paydirt. It was unworkable, unsafe, and inherently unflyable. It would not be fully functional until 2025, as first tier development on many components necessary had not yet even begun. The Ares launchers caused crippling compromises to Orion, sacrificing such features as two crew, part of the service life, ground landing, and reuse.
It helps to understand what Ares began as, and what they became. When originally proposed, there were 4 launchers written up, Ares I, III, IV and V. Ares I was a 4 segment SRB right off of the shuttle with an air-start version of the Shuttles RS-25 for upper stage. Ares III and IV were quick-develop using 3 and 4 RS-25, respectively, mounted to the bottom of the shuttles main fuel tank. Ares V was a 5 engine which also required stretching the shuttles main tank. Management decided on skipping the III and IV first-stage development (called LV 25 and 26 at the time) and pushing forward with Ares I and V. Then, someone decided on a need for a re-startable engine for the Ares I, the RS-25 is not restartable (as it was, to make it air-startable was difficult but not impossible, but to restart them is impossible due to the design). So, they needed the J-2S, but the J-2S off of Ares V was not strong enough, so new engine development, J-2X plus replace the shuttles SRB with new SRB which were 25% larger. But J-2X cost too much, and Ares V needed 2 of them, so they killed one, which then made Ares V not work, so scrapped the RS-25 there and replace with even larger Solid boosters, new engine again, and the Delta IV's RS-68. But the RS-68 has a critical problem of not handling too much heat (the two solid boosters produce TONS of BTU's) and would blow up mid-flight, requiring a new RS-68B model to solve that issue.....
And even now, it still cannot do its job.
