520-Day Mission


The National Space Biomedical Research Institute (NSBRI) participated in the Russian 520-day Mars Mission Simulation conducted by the State Scientific Center of the Russian Federation – Institute for Biomedical Problems (IBMP) of the Russian Academy of Sciences.

A six-man international crew began their 520-day stay inside IBMP's isolation facility in Moscow on June 3, 2010, and the simulation ended Nov. 4, 2011. The crew had a mission schedule full of more than 90 experiments and realistic scenarios, including emergency situations, 20-minute communications delays and a trip to the martian surface.

The mission was broken into 250 days for the trip to Mars, 30 days on the surface, and 240 days for the return to Earth.

Supported by NSBRI, the U.S. scientific team participating in the study monitored the six crew members' rest-activity cycles, performance and psychological responses to determine the extent to which sleep loss, fatigue, stress, mood changes and conflicts occur during the mission.
