The cosmic radiation shielding market size has grown strongly in recent years. It will grow from $1.23 billion in 2025 to $1.34 billion in 2026 at a compound annual growth rate (CAGR) of 8.9%. The growth in the historic period can be attributed to increasing research investments in radiation shielding for crewed space missions, development of nanotechnology-based shielding materials to enhance particle attenuation, rising satellite deployment driving demand for protective materials for onboard electronics, early adoption of simulation and modeling tools to evaluate shielding effectiveness, collaboration between space agencies and material scientists to advance in-situ shielding fabrication methods.

The cosmic radiation shielding market size is expected to see strong growth in the next few years. It will grow to $1.86 billion in 2030 at a compound annual growth rate (CAGR) of 8.5%. The growth in the forecast period can be attributed to growing need for advanced shielding solutions to support long-duration lunar and mars missions, increasing commercialization of space driving demand for lightweight and deployable radiation shields, advancements in multifunctional shielding materials offering combined structural and radiation protection, rising use of training and certification services to meet evolving space safety standards, expansion of private-sector space activities accelerating innovation in scalable radiation shielding technologies. Major trends in the forecast period include increasing development of lightweight radiation shielding for spacecraft mass optimization, rising use of multifunctional shielding materials integrating thermal protection and structural support, growing demand for radiation-resistant materials for long-duration lunar and mars missions, expansion of in-situ shielding technologies for extraterrestrial habitats, heightened adoption of deployable or inflatable shielding systems for mission flexibility.

The rising expenditure on space exploration is expected to drive the growth of the cosmic radiation shielding market in the future. Space exploration expenditure involves funding activities related to exploring outer space and securing national interests through space-based defense initiatives. This increase is motivated by heightened national security concerns, leading countries to invest heavily in protecting their space assets and maintaining strategic dominance in the space domain. A significant portion of this spending is focused on developing advanced shielding technologies to safeguard astronauts and equipment from cosmic radiation, which poses a critical challenge for long-duration missions beyond Earth’s orbit. These investments support research into innovative materials and designs that improve safety and mission success in deep space environments. For example, in April 2024, the World Economic Forum, a Switzerland-based NGO, projected the space economy's value to rise from $630 billion in 2023 to $1.8 trillion by 2035, with an annual growth rate of around 9%. Thus, growing space exploration and defense spending is propelling the cosmic radiation shielding market.

Leading companies in the cosmic radiation shielding market are focusing on innovative solutions such as Series A venture capital to accelerate R&D, commercialize advanced shielding technologies, and support long-duration space missions. Series A venture capital refers to the first major round of equity financing a startup receives from institutional investors or venture capital firms after seed funding, aimed at scaling the business, developing products, and achieving market traction. For example, in June 2023, Zero-Error Systems, a Singapore-based semiconductor company, raised $7.5 million in an oversubscribed Series A funding round to accelerate the development and commercialization of its advanced semiconductor solutions. The funding enables the company to expand R&D in Singapore, grow its team, and support global customer design-in efforts, accelerating global sales, enhancing its product roadmap, and meeting the growing demand for radiation-hardened semiconductor solutions designed for space applications such as low Earth orbit satellites and deep space rovers. Their technology protects commercial off-the-shelf semiconductor devices from cosmic radiation, ensuring power reliability and data integrity critical for space missions and advanced power management on Earth.
