> The ~$5B figure is in the final para. And that still sounds like it excludes ground systems and Orion development costs. (Plus ~4 more years of ever-growing bloat, obviously.) There is a much more official and up to date figure: > We project the cost to fly a single SLS/Orion system through at least Artemis IV to be $4.1 billion per launch at a cadence of approximately one mission per year. https://oig.nasa.gov/docs/IG-22-003.pdf https://oig.nasa.gov/docs/IG-22-003.pdf From what I understand, that number does include ground systems. For what it's worth, NASA leadership continues to contest this value, although they refuse to publicly give their own value. To be fair to you, the $4.1B figure does not include development costs. I don't think there's an agreed upon way to include them, so everyone just mentions them separately. And they are quite... large.
