Costs, delays mount for Boeing's NASA launch system, audit finds

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.
