SmallSat Europe Speaker Focus: Merek Chertkow, The Radiation Team

Why It Matters

By enabling cost‑effective radiation resilience, The Radiation Team accelerates deployment of dense LEO constellations and reduces barriers for satellite startups, reshaping the economics of space hardware. Its expertise also safeguards defense‑grade missions that face heightened radiation exposure in emerging orbital architectures.

Key Takeaways

• Legacy rad‑hard parts cost premium, unsuitable for proliferated LEO constellations
• The Radiation Team models orbit‑specific radiation, enabling COTS component use
• Offers end‑to‑end qualification from concept to flight for startups and defense
• Addresses software‑defined smallsat vulnerabilities highlighted by SDA analysis
• Supports upcoming Blackwing Sparrow nanosatellite pre‑flight testing

Pulse Analysis

Radiation remains the silent adversary of every spacecraft, yet traditional hardening solutions were built for a bygone era of expensive, single‑mission programs. Mil‑spec components and multi‑year qualification pipelines drove costs sky‑high, limiting access for the new wave of low‑cost, high‑volume LEO constellations. As satellite operators shift toward commercial off‑the‑shelf (COTS) electronics, the industry faces a paradox: cheaper hardware but heightened vulnerability unless mitigation is engineered at the system level.

Enter The Radiation Team, founded by former SpaceX and Blue Origin radiation leads. Chertkow’s playbook replaces blanket part‑list hardening with orbit‑specific modeling, quantifying dose rates for each mission profile and embedding shielding, error‑correction, and redundancy where they matter most. This approach directly addresses findings from recent Space Development Agency analyses that flagged persistent radiation gaps in software‑defined smallsats. By delivering end‑to‑end qualification—from early design trade studies to flight‑ready testing—the firm bridges the gap between budget‑constrained startups and the rigorous standards demanded by defense customers.

The broader implication is a democratization of space resilience. As LEO constellations swell and lunar missions emerge beyond Earth’s magnetosphere, the ability to certify COTS‑based hardware quickly and affordably becomes a strategic differentiator. Companies that ignore system‑level radiation engineering risk costly failures, while those that partner with specialists like The Radiation Team can accelerate launch schedules, protect investment, and maintain operational continuity in an increasingly contested orbital environment.
