>Back in the olden days of software, "testing" is where the money was spent to actually make something work. Much less so for space hardware. A large part of the engineering effort goes into testing, but you have a complete thing that gets tested. You don't just half ass the design and completely redo it in testing. These things are all planned for very early on. Hardware design isn't at all agile. You might be right that there is a fundamental flaw that they realize would be extremely expensive to fix.
