The NASA-funded Jet Propulsion Laboratory in La Cañada Flintridge announced on Tuesday that it will lay off about 5% of its staff.

NASA’s Jet Propulsion Laboratory is preparing to lay off hundreds of employees this week, director Laurie Leshin said in a memo to staff sent Tuesday afternoon. The La Cañada Flintridge research institution will let go of approximately 325 employees across the organization on Wednesday,

The layoffs come several months after nearly 600 were let go in an action officials said was due to budget constraints.

Barely nine months after the last cut, NASA's Jet Propulsion Laboratory will again reduce its workforce. On Wednesday, the lab will lay 325 employees off, representing about 5 percent of the workforce at the California-based laboratory that leads the development of robotic space probes for NASA.
