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

In January, 100 on-site contractors at JPL were let go after NASA instructed the lab to reduce spending in anticipation of a much tighter budget. In February, the lab laid off 530 employees — approximately 8% of its workforce — and another 40 contractors.

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.
