NASA's SLS Rocket: $6 Billion Over Budget and 6 Years Late.

NASA's Space Launch System (SLS) rocket, designed to take astronauts to the moon, is $6 billion over budget and six years behind schedule, according to a new audit from NASA's Inspector General. The report foresees "additional cost and schedule increases" that could potentially jeopardize the entire Artemis mission if problems aren't handled. The SLS uses older technology, including engines salvaged from retired Space Shuttles, which has caused cost and schedule overruns. The Inspector General blames the use of "cost-plus" contracts that allow suppliers to inflate budgets more easily, instead of fixed-priced contracts.
