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 Space Launch System (SLS) team of potential layoffs, a worrying sign that NASA’s Moon rocket may be at risk after massive cost overruns and schedule delays. And also Trump.

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.

The aerospace company, which is the primary contractor for the rocket's large core stage, issued the notifications as part of the Worker Adjustment and Retraining Notification (or WARN) Act, which requires US employers with 100 or more full-time employees to provide a 60-day notice in advance of mass layoffs or plant closings.

Boeing announced Friday up to 400 of its workers within the SLS program could lose their jobs by April, putting future Artemis missions into question.

The development of the SLS rocket took too long and was too expensive. A reduced NASA budget could mean the end - and the loss of many jobs.

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.

A 60-day notice of involuntary layoffs will be issued to affected employees by the Seattle-based aerospace manufacturer in the coming weeks.
