Rocket Lab experienced a structural failure of the Neutron rocket's Stage 1 tank during a hydrostatic pressure test on January 21. The incident occurred at the Space Structures Complex in Middle River, Maryland, and resulted in the tank's rupture, while causing no significant damage to the testing facilities.

The company is currently analyzing the situation to assess its impact on the Neutron's launch schedule, which has already been pushed from 2025 to 2026. The next Stage 1 tank is in production, and Rocket Lab plans to provide an update during its upcoming quarterly financial call in February.

Neutron is designed to be a partially reusable two-stage launcher, capable of sending 13,000 kg to low Earth orbit. The first launch was initially expected in 2026, but the tank failure raises concerns regarding potential further delays.
