Neat look at the stages in Ares I's life...

From 2005 through early 2011, NASA conducted concept definition,
design, and development of the Ares I launch vehicle. The Ares I was conceived to serve as a crew launch vehicle for beyond-low-Earth-orbit human space exploration missions as part of the Constellation Program Architecture. The vehicle was configured with a single shuttle-derived solid rocket booster first stage and a new liquid oxygen/liquid hydrogen upper stage, propelled by a single, newly developed J-2X engine. The Orion Crew Exploration Vehicle was to be mated to the forward end of the Ares I upper stage through an interface with fairings and a payload adapter. The vehicle design passed a Preliminary Design Review in August 2008, and was nearing the Critical Design Review when efforts were concluded as a result of the Constellation Program s cancellation. At NASA Glenn Research Center, four subsystems were developed for the Ares I upper stage. These were thrust vector control (TVC) for the J-2X, electrical power system (EPS), purge and hazardous gas (P&HG), and development flight instrumentation (DFI). The teams working each of these subsystems achieved 80 percent or greater design completion and extensive development testing. These efforts were extremely successful representing state-of-the-art technology and hardware advances necessary to achieve Ares I reliability, safety, availability, and performance requirements. This paper documents the designs, development test activity, and results.

Has Boeing inherited all of the ICD's, CAD (CAM?) drawings, test results etc. from NASA for the upper stage to be integrated into SLS?

As penance for being a pain in the ass during the govt shutdown, I'm going to post pictures I took during a tour of the Ares I upper stage test bed at Glenn this summer during my stint as an intern. (I had permission.) After I post the pictures, I'll post a little summary of an interesting technical discussion I had with the guy who ran the testing.

The cone shape is the bottom of the simulated tank. These are some vertical panoramas.

Not all of these pictures are really great, but I figured I'd post them here in case anyone was curious.

The black part at the bottom is the "engine." It's attached firmly to the foundation. It can't be removed. If they want to use this room for something else, they'll have to leave that part in place, perhaps pour concrete over the hole.
