Common Questions
What is BARDA and why is it involved in Artemis II?
BARDA is the US biodefence agency. It partners on AVATAR to study deep-space radiation effects, which advances both space medicine and terrestrial radiological countermeasures.Source: NASA AVATAR experiment overview
What does BARDA normally do?
BARDA develops medical countermeasures for chemical, biological, radiological, and nuclear threats, including vaccines and treatments for public health emergencies.Source: BARDA agency overview
How does space radiation research benefit biodefence?
Deep-space radiation data from crew organ chips informs how ionising radiation damages human tissue, directly relevant to radiological attack countermeasures.Source: NASA AVATAR experiment overview
Who else is involved in the AVATAR experiment?
BARDA partners with NIH/NCATS, Space Tango, Emulate Inc., and the Wyss Institute on the organ-on-chip payload.Source: NASA AVATAR experiment overview

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.
