Later that year, reports surface that the service module is facing mass challenges and other technical problems.But in January 2014, ESA insists the module will be ready for the first flight in 2017.And if that's true, then Ares V would likely also not yet be ready to fly by now, because it would have run into almost identical limits.(Maybe Orion-Ares I would be up by now, but at the expense of uncrewed cargo launches and/or commercial crew vehicle development.Sure, NASA in the 1960's had more money, but NASA in the 2010's has the already-existing technology. Ares development fed directly into SLS development (and both started with Shuttle components as their starting points), they didn't throw away the Ares plans and start SLS totally from scratch.So there's a not-insane argument to be made that cancelling Constellation did very little to really cancel Ares, it just changed the name and a bit of the general layout.Though the rocket has yet to leave the pad, it's been a wild ride for what will eventually become NASA's first new crew vehicle in almost four decades. An operational date for the core vehicle is requested for December 31, 2016.
NASA announces the European Space Agency will provide Orion's service module, which provides the capsule with power and propulsion.NASA announces SLS has passed its KDP-C milestone, which locks in a baseline launch date of no later than November 2018.
