ISS Science for Everyone

Science Objectives for Everyone
Human Research Facility-1 (HRF-1) provides an on-orbit laboratory that enables scientists conducting human life science research to evaluate the physiological, behavioral, and chemical changes induced by space flight. Research performed using HRF-1 provides data to help scientists understand how the human body adapts to long-duration spaceflight.

    Facility Description

    Facility Overview

    Human Research Facility-1 (HRF-1) consists of items mounted in a rack [based on the EXpedite the PRocessing of Experiments to Space Station (EXPRESS) rack design] as well as equipment kept in stowage and brought out as needed.
     
    (HRF-1) was launched aboard STS-102 (Discovery) March 8, 2001 and installed in the U.S. Lab. During Expedition 21/22, it was moved to the Columbus Module. The HRF-1 drawers provide power, command and data handling, cooling air and water, pressurized gas, and vacuum to experiments.
     
    The International Space Station (ISS) moderate temperature cooling loop is extended into the HRF to keep the rack at ambient temperature. Each payload can use up to 500W of power and the sum of all payloads can use up to 2000 W of power. HRF-1 is connected to the ISS video services and Ethernet, which allow the ISS and ground operations crews to control payloads. The rack has front-panel access ports for the laptop, vacuum system, deployed payloads, and nitrogen delivery system. HRF-1 houses many types of equipment.
     
    A stowage drawer holds the Ultrasound 2 which is ultrasound/Doppler equipment that has research and diagnostic applications. When deployed, the Ultrasound 2 is connected to the front of HRF-1 by cables that provide power and allow real-time downlink of scanhead video. Ultrasound images can also be saved to the unit and transferred to the HRF PC for later downlink. The Ultrasound 2 replaced the HRF Ultrasound, which was an HRF-1 rack-mounted device, in 2011.
     
    A portable computer (HRF PC) is used to install and execute software that supports HRF experiments. It is used to control equipment; to collect and store data, crew notes, and equipment notes; and to provide uplink and downlink capabilities. Another PC (designated HRF PC3) containing HRP experiment-specific software utilizes HRF Rack 1 for experiment data downlink. Both HRF PCs are capable of supporting Remote Desktop Protocol (RDP) allowing ground personnel to control of all the software on the HRF PC in real-time.
     
    Two Cooling Stowage Drawers (CSDs) provide stowage for equipment. When in operation, the drawers maintain a uniform temperature by improving air circulation in the rack to remove the heat generated by individual powered payloads that use HRF-1.
     
    The HRF 8PU Utility Drawer (installed in Expedition 36) provides stowage for consumables with added radio-frequency identification (RFID) capability built in that automates inventory of the RFID-tagged contents without crew intervention. The drawer also provides power and data connections on the front panel for deployed equipment requiring rack power. A second HRF 8PU Utility Drawer, which was launched on OA-4 during Expedition 45/46 and originally installed in HRF-2, was relocated to HRF-1 during Expedition 55/56 to allow a new centrifuge to be installed in HRF-2.
     
    The Space Linear Acceleration Mass Measurement Device (SLAMMD) was installed in HRF-1 during Expedition 11. The SLAMMD measures the on-orbit mass of the crew members by applying Newton's second law of motion (force equals mass times acceleration). This device can measure a mass between 95 and 240 lb using the force generated by two springs inside the SLAMMD drawer. Each spring is attached to a cam, which is also attached to a centrally located shaft with a flywheel mounted on top of it. The cam is designed such that, as the springs are stretched over a distance, a constant force is applied to the central shaft. A lanyard wrapped around the large flywheel is fed through a small slit on the SLAMMD front panel. The lanyard is latched onto the SLAMMD guiding arm, where the crew member sits for a body mass measurement. Attached to the guiding arm is a leg support assembly around which the crew member wraps his or her legs (as one would for a leg curl machine), a belly pad to help align the stomach, and a headrest. Hardware that is detached from SLAMMD when it is not deployed is stowed in an 8PU drawer. This drawer was removed and stowed outside HRF-1 when the HRF Racks were reconfigured during Expedition 55/56.
     
    HRF-1 was originally launched with the following components: the HRF Ultrasound, Gas Analyzer System for Metabolic Analysis Physiology (GASMAP), portable computer, workstation, and cooling stowage drawers. During Expedition 11, the GASMAP was moved to Human Research Facility 2 (HRF-2), and SLAMMD was moved to HRF-1 from HRF-2. During Expedition 13, the original workstation was replaced with the Workstation 2. During Expedition 28, the HRF Ultrasound was replaced with the Ultrasound 2. During Expedition 36, an 8PU Utility Drawer replaced one passive 4PU stowage drawer and the Workstation 2. During Expedition 55/56, an HRF 8PU Utility Drawer from HRF-2 replaced the SLAMMD Stowage Drawer in HRF-1 (the latter is now stowed outside the HRF Racks).
     
    Payloads in HRF-1 can operate independently of each other regardless of their cooling and power needs and the flight schedule. The HRF power converter delivers 120V of direct current (DC) power from the utility outlet panel to the rack and converts it to 28 Vdc for distribution to the payloads. Payload computer and video operations can be conducted from the ground or on the space station. The crew performs periodic checks of all connections and hardware and performs payload operations as needed.
