description: "Momentus reported that its Vigoride 7 orbital vehicle successfully completed over 50 controlled thruster firings, reducing altitude by nearly 20 km. The test validated a 3D-printed titanium fuel tank holding pressure as designed and demonstrated stable performance from first in-orbit momentum wheels. Additionally, the water-propellant Microwave Electrothermal Thruster system has been used over 400 times since 2023, supporting technology maturity claims for additive manufacturing in spacecraft production."
