The Radiation Shield: Decoding Cellular Survival in Deep Space
When we design biological systems for outer space, we face an invisible, relentless enemy: cosmic radiation. Galactic Cosmic Rays (GCR) and unpredictable Solar Particle Events (SPE) strike with massive biological effectiveness. For both human astronauts and engineered microbes, unshielded space radiation shreds DNA, creates complex cellular mutations, and limits the very viability of long-duration missions to the Moon and Mars.
Welcome to Week 2 - Shield & Build: Deep Space Health & Off-World Manufacturing. To build a sustainable future on the high frontier, we must first understand the absolute boundaries of biological survival.
Join us for a masterclass briefing titled "The Radiation Shield: Decoding Cellular Survival in Deep Space," featuring PD Dr. med. vet. Christine E. Hellweg, Vice Director of the Institute of Aerospace Medicine and Head of the Cellular Protection Mechanisms working group at the German Aerospace Center (DLR).
Dr. Hellweg will deliver a comprehensive look into space radiation biology. Moving past low Earth orbit protections, she will reveal exactly how cosmic heavy ions and high-energy radiation impact cellular and molecular structures. Discover how researchers map out DNA damage and repair kinetics, how gravity interacts with radiation responses, and how these vital insights define the ultimate safety, architectural, and engineering limits for deploying synthetic biology and life-support systems in deep space.
What you’ll learn:
The Deep Space Radiation Field: The biological difference between Earth-orbit protection and the true interplanetary radiation environment.
Cellular Battlegrounds: How cosmic radiation triggers complex DNA double-strand breaks, inflammatory responses, and gene expression changes.
Engineering the Limits: How DLR maps bio-dosimetry and cellular survival to establish concrete guardrails for off-world biological manufacturing and astronaut health.
If you are a synbio engineer designing robust strains for space, a medical professional interested in space medicine, or an aerospace enthusiast, this briefing will show you exactly what it takes to survive the cosmos.
🎤 About the speaker
PD Dr. med. vet. Christine E. Hellweg - Vice Director, Institute of Aerospace Medicine at DLR
PD Dr. Christine E. Hellweg is a premier global authority in space life sciences and radiobiology. She serves as the Vice Director of the Institute of Aerospace Medicine at the German Aerospace Centre (DLR) in Cologne, where she also leads the Cellular Protection Mechanisms working group within the Radiation Biology department. Holding an extensive background in veterinary medicine, immunology, and molecular biology from the Freie Universität Berlin, Dr. Hellweg has spent decades investigating how extreme environments impact living systems at the cellular level.
As a Principal Investigator for numerous heavy-ion accelerator experiments and a key contributor to breakthrough space life science initiatives, such as the BioMoon mission concept, she routinely evaluates space radiation risks and countermeasures. Her pioneering research shapes radiation protection, biodosimetry, and safety frameworks for the European Space Agency (ESA), the European Commission, and the global space flight sector.
