jsc2016e107373 (8/29/2016) --- Photographic documentation taken of REALM-1 (ISS OPNOM RFID Logistics) flight hardware in bldg 14 prior to delivery for launch. The RFID-Enabled Autonomous Logistics Management (REALM) (RFID Logistics Awareness) investigation tests a radio-based inventory control system to keep track of everything inside the football-field-sized ISS. Some aspects of the technology are commonly used on Earth, but other aspects are experimental in nature.

Sellers, STS-112 mission specialist, uses virtual reality hardware in the Space Vehicle Mockup Facility at the Johnson Space Center (JSC) to rehearse some of his duties on the upcoming mission to the International Space Station (ISS). This type of virtual reality training allows the astronauts to wear a helmet and special gloves while looking at computer displays simulating actual movements around the various locations on the International Space Station (ISS) hardware with which they will be working.

This diagram shows the flow of recyclable resources in the International Space Station (ISS). The Environmental Control and Life Support System (ECLSS) Group of the Flight Projects Directorate at the Marshall Space Flight Center is responsible for the regenerative ECLSS hardware, as well as providing technical support for the rest of the system. The regenerative ECLSS, whose main components are the Water Recovery System (WRS), and the Oxygen Generation System (OGS), reclaims and recycles water and oxygen. The ECLSS maintains a pressurized habitation environment, provides water recovery and storage, maintains and provides fire detection / suppression, and provides breathable air and a comfortable atmosphere in which to live and work within the ISS. The ECLSS hardware will be located in the Node 3 module of the ISS.

STS079-302-006 (16-26 Sept. 1996) --- Astronauts Jerome (Jay) Apt (right) and Carl E. Walz, both mission specialists, tilt the Active Rack Isolation System (ARIS) hardware which was included on this flight to evaluate conditions and hardware requirements for the International Space Station (ISS). The ARIS is designed to isolate certain experiments from major disturbances that are expected to be found on the ISS, such as vibrations caused by the movement of mechanisms and crew members and the operation of equipment. STS-79 was chosen for the inclusion of the experiment because the Shuttle-Mir complex more closely approximates the acceleration environment of the ISS.

ISS011-E-09359 (21 June 2005) --- Astronaut John L. Phillips, Expedition 11 NASA ISS science officer and flight engineer, tries to sort out various hardware in the Unity node of the International Space Station (ISS).

The Jet Propulsion Laboratory has designed and built an electronic nose system -- ENose -- to take on the duty of staying alert for smells that could indicate hazardous conditions in a closed spacecraft environment. Its sensors are tailored so they conduct electricity differently when an air stream carries a particular chemical across them. JPL has designed and built a 3-pound flight version (shown with palm-size control and data computer). The active parts are 32 sensors, each with a different mix of polymers saturated with carbon. When certain chemicals latch onto a sensor, they change how the sensor conducts electricity. This signal tells how much of a compound is in the air. The electronic nose flown aboard STS-95 in 1998 was capable of successfully detecting 10 toxic compounds.

The ISS is shown in the configuration that it was during the STS-121 mission. The background shows the nighttime Earth with a dawn breaking over the horizon. STS-121, ISS mission ULF1.1, was the final Shuttle Return to Flight test mission. This utilization and logistics flight delivered a multipurpose logistics module (MPLM) to the ISS with several thousand pounds of new supplies and experiments. In addition, some new orbital replacement units (ORUs) were delivered and stowed externally on the ISS on a special pallet. These ORUs are spares for critical machinery located on the outside of the ISS. During this mission the crew also carried out testing of Shuttle inspection and repair hardware, as well as evaluated operational techniques and concepts for conducting on-orbit inspection and repair.

The ELaboratore Immagini TElevisive - Space 2 (ELITE-S2) facility provides the experiment hardware to investigate the connection between brain, visualization and motion in the absence of gravity.

jsc2021e066967 (9/2/2021) --- A preflight view of the Tanpopo-4 hardware. Tanpopo is a Japanese astrobiological space exposure experiment on ISS. There are 7 small cells containing microorganisms, mosses and organic compounds to be determined their stabilitites and alterations (Tanpopo-4).

Water and nutrients are being added to plants in the Veggie hardware in NASA Kennedy Space Center's ISS environment simulator chamber. Mizuna mustard, Outredgeous lettuce and Waldmann's green lettuce are growing in Veggie. Growth in the chamber mimics the growth of plant experiments in the Veggie plant growth system on the International Space Station.
