NASA responded to news that Boeing aims to lay off up to 400 workers from its Space Launch System program. The SLS rocket plays a key role in the Artemis moon program, the agency said.

Boeing informed its employees working on NASA's Artemis program that it was preparing for as many as 400 layoffs connected to the giant rocket under development amid possible shakeups to the country's return-to-the-moon initiative, the company said.

Boeing told employees in its SLS moon rocket program on Saturday that it plans to make around 400 layoffs as NASA's Artemis program suffers delays and cost revisions.
