Our Story
Particle Path Assurance was founded in 2024 with a clear mission: to be the first radiation effects testing facility designed specifically for industrial space customers. Unlike traditional university research labs, government facilities, or repurposed medical centers, we prioritize commercial space companies' needs with transparent processes, modern logistics, and space-industry expertise.
Our founders recognized that the space industry was rapidly expanding, but radiation effects testing facilities hadn't evolved to meet the unique needs of commercial space companies. Traditional facilities were designed for academic research or government programs, leaving commercial space companies struggling with long wait times, opaque processes, and facilities not optimized for their operational requirements.
We built Particle Path Assurance from the ground up with space industry customers in mind. Every aspect of our facility, from the dual-beam capability to the 24/7 operations, is designed to support the fast-paced, mission-critical nature of commercial space operations.
Our Mission
To provide industrial-first radiation effects testing that enables commercial space companies to validate their missions with confidence, speed, and transparency.
Our Vision
To be the trusted partner for radiation effects testing as the space economy scales from startups to major aerospace companies.
