105-Day Mission

The National Space Biomedical Research Institute (NSBRI) participated in the 105-day isolation study to gather data on crew health and performance during long-duration space missions. NSBRI's three research projects evaluated lighting countermeasures, measured the impact of stress and fatigue on work performance, and assessed interactions between crew members and with "mission control."

An international crew, consisting of four Russians and two European Space Agency-selected participants, began its 105-day stay inside the Institute for Biomedical Problems' (IBMP) isolation facility in Moscow on March 31, 2009. The crew members participated in activities simulating aspects of a long-duration spaceflight. The mission ended July 14.

The 105-day study was conducted through a partnership between IBMP and the European Space Agency. NSBRI participated through an international agreement with IBMP and managed the United States' scientific activities during the study.

IBMP's isolation facility is comprised of interconnected, self-contained modules that have medical and scientific research areas, sleeping quarters, a kitchen and an exercise facility.
