Boeing is exploring the sale of its space business, the Wall Street Journal has reported, citing people familiar with the matter.
The NASA business includes the troubled Starliner space vehicle and operations that support the International Space Station.
The US planemaker was not immediately available to respond to a Reuters request for comment.
The struggling aerospace company's Starliner spacecraft has been hindered for years by development delays and technical problems, with more than $1.8 billion in private cost over runs.
Two NASA astronauts that Boeing brought to the International Space Stations remain stuck there and are scheduled to return in February on a craft from rival SpaceX.
Boeing is also grappling with a labor action by about 33,000 workers at its civil planemaking arm leading to halt in production of its best-selling 737 MAX jets, and 767 and 777 widebodies.
