“The Government Accountability Office highlighted other potential problems, including too much weight in both the rocket and Orion capsule, design issues with a new engine for a booster, insufficient facilities for certain types of testing, and private industry’s inability to make the Orion capsule’s 1960s-style peel-away heat shield. None of the technical problems are “a fatal flaw,” the report’s author, Christine Chaplain told a House Science subcommittee Thursday.”

“But during a design review for Ares I in October 2007, engineers calculated that the rocket might vibrate so severely in the first few minutes of launch that it could actually destroy itself, threatening astronauts’ lives. The problem was made public in January, after the independent website NASA Watch and the Associated Press questioned NASA and filed Freedom of Information Act requests with the agency.”
