Steve Cook, manager of the Ares I rocket at MSFC, stated, "Risk assessment is a very important part of the process. It allows us to identify issues that might impact the Ares I rocket. For example, we identified thrust oscillation - vibration in the first stage - as a risk. In response to this issue, we formed an engineering team. The team conducted detailed analyses and reviewed previous test data, and then recommended options to correct the problem."

Cook added, "We intend to hold a limited follow-up review next summer to fully incorporate the thrust oscillation recommendations into the stacked vehicle design. Identifying risks that can impact the project and resolving them is a necessary and vital part of the development process."

Now with the PDR completed, the detailed design phase will be implemented for the Ares I rocket.

First on the docket, according to NASA, is the critical design review process for the J-2X engine. It will supply power for the Ares I upper stage that sends the Orion space capsule into orbit after it separates from the Ares first stage. (See a video of the J-2X engine on YouTube.)

Cook comments: "We're excited about getting into full system engine tests with the new J-2X engine. This will be one of the safest, most affordable and highest performing rocket engines ever built, and testing is critical as we begin preparation for future flights."

The Ares I rocket is part of Project Constellation, the next-generation manned space program for the United States, which is directed by the National Aeronautics and Space Administration (NASA).
