Engineers at Lockheed Martin are adding structural braces to fix the cracks found in the first Orion capsule.
Engineers have designed a “doubler” to place over the cracks to ensure the craft can sustain loads from pressure, launch and landing. Geyer said two of the structural aids, similar to devices regularly used on airplanes, could be added to the spacecraft. “We’ve come up with a great plan to basically bridge over those cracks to distribute the load so we don’t see any issues on orbit,” Geyer said.
How reassuring.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I can only imagine the sorts of development problems that SpaceX and others have had with their items, but we’ll never know. As a federal program, everything is laid bare, by law.
What? You think SpaceX gets everything correct 100% of time? Of course they don’t. But they are not compelled to tell you anything about their missteps.
Aw, crud, I mistyped. I meant to say:
“With Orion, as a federal program, everything is laid bare, by law”
What they are adding, the rest of the world just calls ‘gussets’.
It just means they cut their design way to close to the structural limits of the material they are working with.
I bet they cut the material thickness back as far as possible just to save weight. And now that they have to add material to the structure to strengthen it they are losing a portion of that savings.
Just engineers over engineering something and typically running into problems easily foreseen that they thought they were smart enough to get around.
But this could be excused as exactly what we want NASA to do. Push the boundaries of everything right up to the breaking point so that private industry has a better idea of what they themselves can do in the real world.
I just wish their working projects didn’t cost so much and fail so regularly.
Reminds me of the saying…”You don’t want to ever see how sauseges are made.”
But I make sausage.
It would be nice to read Kelly’s opinion on this.
