Develops deployable space solar arrays and radiators that launch compact (dining table size) and expand to football-field scale in orbit. Targets the 500x increase in space power demand expected by 2030, driven by orbital datacenters, space stations, and lunar outposts.
Patented deployable design (Pop-Up Extending Trusses/PETS and Hierarchical High-Expansion Ratio Deployable Structures/HERDS). LOIs from space companies totaling over $175M. First in-space demo flight planned Q2 2027. Technology delivers 10x more usable power without increasing launch mass. 100kW+ systems for orbital data centers.
Founded with NASA NIAC grant and Carnegie Mellon research funding. Core technology invented during Fogelson's PhD. Advisors include former AFRL Chief Scientist and MIT Aeronautics & Astronautics professor. Long-term vision: kilometer-scale space infrastructure including artificial-gravity stations.
AI-powered digital twins simulate the full deployment sequence of football-field-scale solar arrays in orbit, enabling real-time optimization of unfolding mechanics before and during mission execution.
A virtual copy of the solar array unfolds itself thousands of times in a computer before the real one ever tries it in space.
It's like rehearsing a giant origami unfold a million times in a video game so the one time you do it for real in zero gravity, every crease lands perfectly.
ML-driven anomaly detection continuously monitors deployed solar array structural integrity in orbit, predicting degradation and triggering autonomous protective responses before failures occur.
Smart sensors on the solar array act like a nervous system that feels damage coming before it happens and automatically protects itself.
It's like giving a bridge the ability to feel its own cracks forming and automatically reroute traffic away from the weak spots before anything breaks.
Generative AI and topology optimization algorithms explore millions of deployable structure configurations to discover novel array geometries that maximize power density while minimizing mass and stowed volume.
An AI architect designs millions of possible solar array shapes overnight and picks the ones that fold smallest, weigh least, and generate the most power.
It's like asking a million architects to each design a different folding umbrella overnight, then picking the one that folds into a thimble but opens to cover a parking lot.
Dr. Mitchell Fogelson (PhD CMU) invented BRL's core technology during his PhD working with NASA on kilometer-scale deployable structures. Published in top robotics and aerospace journals, received Editor Choice Best Paper Award from ASME JMD 2023. Pele Collins spent ~7 years at SpaceX leading Dragon parachute engineering and production across 30+ missions, also worked as Plasma-Facing-Components Technical team lead at Commonwealth Fusion Systems. Friends since 2013 as UPenn freshmen — 13 years of co-founder alignment.
