Space Station Live: The Measure of the Marrow.

NASA Commentator Brandi Dean talks with Drs. Guy Trudel and Odette Laneuville of the University of Ottawa about the MARROW experiment now underway on board the International Space Station. The researchers believe that in weightlessness bone marrow may produce more fat cells than blood cells and leave astronauts susceptible to things like anemia or infection, similar to patients on Earth who are restricted to bed rest. In this experiment they’re gathering samples from space station crew members before, during and after their flights to measure for fat content in the marrow and begin to develop countermeasures that would help keep future astronauts safe on long-duration missions.
