But that’s how all of SLS+Orion decision making has been. If all you have is a hammer, every problem looks like a nail. Virtually every decision has had a pre-determined outcome: If at all possible do it like Shuttle. If not, do it like Apollo.

It's not like solar arrays in space is cutting edge technology.

First use on a NASA capsule! /s

More than 200 billion in today's money and they can only come up with 8 things. Several of which like freeze-dried foods pre-date the program anyway.But I'm sure most people here are smart enough to evaluate a source and can identify it as a public relations handout and won't be prone to feeding an echo chamber.....right?

What's the x-axis?
Nah, I get the message of the graph -- it's just the inaccurate presentation that annoys me as an admitted data viz geek. (And, to be honest, I would generally hope for better from a technically-inclined "Senior Space Editor" at Ars.)
The X axis does not really need to be labeled. It is date and can easily be inferred from the blue line on the Y axis. There are six data points across approximately 7 years (2011 to 2018).
