NASA's flagship space launch system being built by Boeing is taking years longer than expected with cost overruns of nearly $2 billion, an audit found Wednesday, raising questions about meeting a goal of returning humans to the moon by 2024.
The General Accounting Office (GAO) identified $1.8 billion in cost overruns, including $800 million that NASA obscured in previous reports on its Space Launch System (SLS), the rocket and capsule that will eventually take humans back to the moon.
The issues around the rocket's development, led by Boeing Co, mean that the first launch of the SLS originally scheduled for late 2017 could be delayed until June 2021.
Boeing's space division restructured the SLS leadership team in 2018 and early 2019 to adjust to the program challenges and simplified its manufacturing process, Boeing spokesman Jerry Drelling said.
