Company profile
researched Aug 2026Cosmic Shielding is an Atlanta-based space hardware company that develops radiation shielding built on its Plasteel technology. The company offers ready-to-integrate VPX enclosures and NVMe shields as well as fully custom shielded designs, with the stated aim of allowing modern commercial off-the-shelf (COTS) electronics — GPUs, storage devices, sensors, FPGAs, systems-on-module and systems-on-chip — to operate in high-radiation orbital environments from low Earth orbit to geostationary orbit and deep space.
The company positions its shielding as a way for spacecraft teams to shorten the path from concept to flight while reducing mass and cost relative to traditional radiation-hardened systems. Reported test results include reduction of radiation-induced single event effects by up to 10x (180 MeV/n xenon at HIMAC, on an Nvidia Jetson Orin NX 8GB), up to 7x longer mission operating life (63 MeV protons at TRIUMF, same device), and up to 15x cost savings versus conventional rad-hard hardware. Plasteel-shielded systems have flown on orbital missions and, according to the company, are currently shielding AI-capable GPUs and precision cameras in space.
Business model
Cosmic Shielding supplies radiation-shielded hardware products and engineering services to space hardware builders, offering both standardized product lines (VPX enclosures, NVMe shields) and custom shielded designs, alongside government contract work such as an awarded Pentagon TACFI contract.
Traction
Plasteel-shielded hardware reached orbit on the SpaceX Transporter-10 mission (March 2024, aboard Quantum Space's Scout-1), on Transporter-11 (August 2024, with Aethero, described by the company as the fastest Nvidia GPU system in space), and on Transporter-13 (March 2025, three shielded systems). The company lists CERN, the International Space Station, TRIUMF, HIMAC and NASA among mission partners and testing venues, and reports a $4M Pentagon contract awarded in 2025.
Latest developments
In September and October 2025 the company announced a $4M Pentagon TACFI contract to accelerate deployment of advanced space electronics. Three Plasteel-shielded systems launched on the Transporter-13 mission in March 2025, and the company announced a partnership with Aethero on a mission to develop capabilities for AI applications in Earth observation and in-space autonomy.
▸Full profile — market position, technology, go-to-market, geography
Market position
Cosmic Shielding presents itself as an alternative to traditional radiation-hardened electronics, claiming up to 15x cost savings, and has demonstrated flight heritage across multiple SpaceX rideshare missions.
Rather than requiring purpose-built radiation-hardened parts, the company shields commercially available electronics, enabling use of current-generation AI-capable GPUs and other COTS components while reducing lead time, mass and cost.
Technology
The core technology is Plasteel, a radiation shielding material/enclosure approach applied around commercial off-the-shelf electronics. It has been evaluated in particle-beam testing at facilities including HIMAC (180 MeV/n xenon) and TRIUMF (63 MeV protons) using an Nvidia Jetson Orin NX 8GB as the test article, with reported reductions in single event effects and extended operating life. Product formats include VPX enclosures, NVMe shields and custom shielding designs.
Go-to-market
The company sells directly to mission builders through its website and engages in partnerships with payload and edge-computing companies such as Aethero, together with U.S. defense contract awards.
Spacecraft, satellite and space-payload engineering teams deploying compute, storage, imaging and sensing hardware in orbit, plus defense customers via U.S. government contracting.
Geography
Headquartered in Atlanta, United States, with testing and mission partners including TRIUMF (Canada), HIMAC (Japan), CERN and NASA, and hardware flown on U.S. launches.
