Cosmic Shielding Corporation

Cosmic Shielding Corporation is a US-based advanced materials company developing Plasteel — a novel multifunctional shielding polymer claimed as the world's first structural material that simultaneously provides radiation protection and load-bearing capability for spacecraft, potentially enabling significant mass savings compared to traditional spacecraft shielding approaches that add dedicated radiation shielding mass without structural contribution.

Conventional spacecraft radiation shielding faces a fundamental mass efficiency problem: the trapped radiation environments of the Van Allen belts (primarily electrons up to several MeV and protons up to hundreds of MeV) and galactic cosmic rays damage sensitive electronics, degrade solar cells, and threaten crew health, requiring protective shielding. Traditional solutions include thick aluminum walls (high density, adds structural mass), graded-Z shields (multiple layers of different atomic number materials optimized for specific particle spectra), and hydrogen-rich polyethylene panels (effective against proton/neutron radiation). Each approach adds non-structural mass that drives up launch cost at $3,000-30,000/kg depending on the vehicle.

Plasteel's claimed innovation is delivering radiation attenuation through the spacecraft structural material itself — meaning the housing that provides mechanical protection and structural rigidity simultaneously provides radiation shielding, potentially replacing or supplementing aluminum walls with a lighter dual-purpose material. For CubeSats and small satellites where every gram of non-payload mass is costly, an integrated structural-shielding material could meaningfully improve payload fraction.

Three Plasteel systems were launched aboard a SpaceX Transporter-13 rideshare mission — validating that Plasteel survives the mechanical loads of launch and the thermal cycling of early on-orbit operations. The Air Force Research Laboratory (AFRL) awarded $4 million for electronics performance modeling, tasking Cosmic Shielding with characterizing how Plasteel protects specific electronics components from defined radiation dose rates and particle spectra — the technical data required for DoD satellite program qualification and for demonstrating radiation shielding effectiveness to potential satellite manufacturer customers.

The AFRL contract signals defense customer interest in Plasteel for military satellite programs operating in challenging radiation environments (MEO orbits, beyond GEO, nuclear event survivability scenarios). Competitors include traditional shielding suppliers (Ultramet for refractory shields, Materion for graded-Z shield products) and emerging materials approaches from startups developing boron nitride nanotube (BNNT) and polymer composite radiation shielding technologies.
