Background

BARDA is a partner on the AVATAR organ-on-chip experiment aboard Orion, contributing biodefence expertise to deep-space radiation research on the first crewed lunar flight since Apollo.

The Biomedical Advanced Research and Development Authority is part of the US Department of Health and Human Services. Normally focused on medical countermeasures for chemical, biological, radiological, and nuclear threats, BARDA funds the development of vaccines, therapeutics, and diagnostics for public health emergencies.

BARDA's involvement reflects the dual-use Nature of the AVATAR technology. Radiation response data gathered from crew-specific organ chips in deep space has direct applications in BARDA's terrestrial mandate: understanding how ionising radiation damages human tissue at the cellular level informs both space medicine and radiological countermeasure development.

Common Questions
What is BARDA and why is it involved in Artemis II?
