Key hardware includes a laptop computer, computer workstation, ultrasound imager and gas analyzer.
The Human Research Facility provides an on-orbit laboratory that will enable life science researchers to study and evaluate the physiological, behavioral and chemical changes in human beings induced by space flight. Research performed with the Human Research Facility will provide data relevant to longer term adaptation to the space flight environment. The Human Research Facility is a rack which provides services and utilities to experiments and instruments installed within it. These include electrical power, command and data handling, cooling air and water, pressurized gases and vacuum. The first of two Human Research Facility racks will be transported to the International Space Station during the second expedition.
