One of the goals of SLS was to reuse remaining hardware from NASA’s Shuttle program where possible. This was intended to be a cost-saving measure, but given the high price of a single SLS stack costs more than two billion dollars: The SLS rocket for Artemis II (and each Artemis mission) costs approximately $4.1 billion per launch per the NASA OIG, with about half of that being tied up in the rocket and capsule. That’s a lot of money.
Still, there a lot of previously flown pieces of hardware on America’s newest moon rocket.
