Tolerance or Total Immunity?

For decades, designing electronics for space meant choosing between two extremes. Engineers could use radiation-hardened components that would survive high radiation exposure, although they would be more costly and slower to produce. Or they could rely on commercial-off-the-shelf electronics that delivered higher performance but little protection once they left Earth.

That clear divide is fading. Advances in design, testing, and manufacturing have changed the meaning of radiation resistance. Engineers now have more ways to balance performance, reliability, and cost efficiency without compromising mission goals or safety. The result is a new generation of radiation-resistant components that deliver the right level of protection for the environment they’re built for.

From Hardening to Tolerance

Radiation hardening has always been the benchmark for reliability. These components are designed to withstand the cumulative effects of ionizing radiation and single-particle strikes that can cause logic errors, latch-ups, or long-term degradation. Their performance is proven, and government and commercial customers alike are willing to pay for it, from oil and gas exploration to military and defense. The stakes are high, after all.

As mission demands expand from orbit to ocean, from geospatial observation to unmanned terrestrial systems, engineers face new priorities. Low-Earth-orbit constellations, CubeSats, and tactical defense platforms operate on tighter budgets and faster production cycles, driving the need for components that are reliable, scalable, and economical. Similar pressures exist in autonomous vehicles, marine exploration, and defense communications, where systems must handle radiation and thermal stress without the cost or lead times of complete hardening.

For these use cases, radiation-resistant devices strike the right balance, delivering protection from typical environmental exposure while maintaining the agility and scalability needed for shorter missions or faster production timelines.

Matching Protection to Mission Demands

Radiation resistance is not a one-size-fits-all measure. The right level depends on where and how the system operates. Spacecraft and deep-space probes require full hardening to ensure continuous operation through years of exposure. By contrast, low-orbit satellites, autonomous vehicles, and surface-based defense systems can perform reliably with components designed for tolerance rather than total immunity.

This shift is transforming how engineers approach reliability. Rather than defaulting to the highest level of hardening, they are choosing components that align with each mission’s unique risk, cost, and timeline. This model expands accessibility to the right radiation- and heat-resistant chips for the job – across the industry.

A Complete Portfolio of Resistance and Reliability

VORAGO’s expanding portfolio spans the full spectrum of radiation and heat-resistant solutions. From scalable, cost-effective processors like the VA4XXXX and VA4XXXX Vega to customizable, high-reliability VA42XXX, every design offers a tailored balance of protection, performance, and cost. This flexibility allows any customer to meet mission requirements, whether in orbit, undersea, or across terrestrial defense and commercial environments, without unnecessary redesign or delay.

Both the government and the private sector demand this kind of adaptability. From defense and aerospace programs to new energy exploration and global satellite networks supporting media and communications, radiation-resistant components are helping engineers push performance further, faster, and more efficiently than ever before.
