Astronaut James S. Voss, Expedition Two flight engineer, works with a series of cables on the EXPRESS Rack in the United State's Destiny laboratory on the International Space Station (ISS). The EXPRESS Rack is a standardized payload rack system that transports, stores, and supports experiments aboard the ISS. EXPRESS stands for EXpedite the PRocessing of Experiments to the Space Station, reflecting the fact that this system was developed specifically to maximize the Station's research capabilities. The EXPRESS Rack system supports science payloads in several disciplines, including biology, chemistry, physics, ecology, and medicine. With the EXPRESS Rack, getting experiments to space has never been easier or more affordable. With its standardized hardware interfaces and streamlined approach, the EXPRESS Rack enables quick, simple integration of multiple payloads aboard the ISS. The system is comprised of elements that remain on the ISS, as well as elements that travel back and forth between the ISS and Earth via the Space Shuttle.

Developed by Boeing, at the Marshall Space Flight Center (MSFC) Space Station Manufacturing building, the Window Observational Rack Facility (WORF) will help Space Station crews take some of the best photographs ever snapped from an orbiting spacecraft by eliminating glare and allowing researchers to control their cameras and other equipment from the ground. The WORF is designed to make the best possible use of the high-quality research window in the Space Station's U.S. Destiny laboratory module. Engineers at the MSFC proposed a derivative of the EXPRESS (Expedite the Processing of Experiments to the Space Station) Rack already used on the Space Station and were given the go-ahead. The EXPRESS rack can hold a wide variety of experiments and provide them with power, communications, data, cooling, fluids, and other utilities - all the things that Earth-observing experiment instruments would need. WORF will supply payloads with power, data, cooling, video downlink, and stable, standardized interfaces for mounting imaging instruments. Similar to specialized orbital observatories, the interior of the rack is sealed against light and coated with a special low-reflectant black paint, so payloads will be able to observe low-light-level subjects such as the faint glow of auroras. Cameras and remote sensing instruments in the WORF can be preprogrammed, controlled from the ground, or operated by a Station crewmember by using a flexible shroud designed to cinch tightly around the crewmember's waist. The WORF is scheduled to be launched aboard the STS-114 Space Shuttle mission in the year 2003.

ISS006-E-08773 (14 December 2002) --- View of a bubble formed as a result of a Zeolite Crystal Growth (ZCG) experiment in the Destiny laboratory on the International Space Station (ISS). Expedition Six Commander Kenneth D. Bowersox used a Space Station drill to mix 12 Zeolite samples in clear tubes. Scientists on the ground watching on TV noticed bubbles in the samples. Bowersox used a modified mixing procedure to process autoclaves to isolate bubbles.  He re-inserted the samples in the ZCG furnace in Express Rack 2 in the U.S. laboratory/Destiny. This experiment has shown that the bubbles could cause larger number of smaller deformed crystals to grow. Bowersox rotated the samples so that the heavier fluid was thrown to the outside while the lighter bubbles stayed on the inside.

iss056e158493 (Aug. 27, 2018) --- NASA astronaut Serena Auñón-Chancellor works to calibrate a Bone Densitometer aboard the International Space Station's U.S. Destiny laboratory. The device measures the mass per unit volume (density) of minerals in bone using using Dual-Energy X-ray Absorptiometry (DEXA). It is being developed from commercial off-the-shelf hardware and is being designed to fit into an EXPRESS Rack locker. The Bone Densitometer takes quantitative measures of bone loss in mice, during orbital space flight, which are necessary for the development of countermeasures for human crew members, as well as for bone-loss syndromes on Earth, by commercial entities. Planned studies, both academic and commercial, require on-orbit analytical methods including bone densitometry.

iss056e195892 (Sept. 27, 2018) --- Flight Engineer Serena Auñón-Chancellor of NASA monitors the arrival of the H-II Transfer Vehicle-7 (HTV-7) before it was captured during Expedition 56 by Commander Drew Feustel operating the Canadarm2 robotic arm. The HTV-7 from the Japan Aerospace Exploration Agency (JAXA) delivered six new lithium-ion batteries and adapter plates to upgrade the International Space Station's power systems. The Japanese resupply ship also delivered science experiments and research hardware including a new sample holder for the Electrostatic Levitation Furnace (JAXA-ELF), a protein crystal growth experiment at low temperatures (JAXA LT PCG), an investigation that looks at the effect of microgravity on bone marrow (MARROW), a Life Sciences Glovebox, and additional EXPRESS Racks.

SL3-88-004 (July-September 1973) --- A vertical view of the Salinas River Valley area south of Monterey Bay, California area is seen in this Skylab 3 Earth Resources Experiments Package S190-B (five-inch Earth terrain camera) photograph taken from the Skylab space station in Earth orbit. The valley is an irrigated agricultural area, and is indicated by the dark-green and light-gray rectangular patterns in the centre of the picture. The city of Salinas is barely visible under the cloud cover at the top (north) end of the valley. The dark mass on the left (west) side of the valley is the Santa Lucia mountain range. The Big Sur area is on the left and partly covered by clouds. The Diablo Range forms the dark mass in the lower right (southeast) corner of the photograph. The town of Hollister is the gray area in the dark-green rectangular farm tracts which occupy the floor of the San Benito Valley in the upper right (northeast) corner of the photograph.  The Salinas River flows northwestward toward Monterey Bay. The towns of Soledad, Greenfield and King City appear as gray areas along U.S. 101 in the Salinas Valley. The geology of the area is complex, and has been racked by several earthquakes resulting from movement along the San Andreas and subsidiary faults.  Here, the surface expression of the San Andreas Fault can be traced from a point just west of Hollister at the contrast of dark brown and tan to a point about one inch left of the lower right (southeast) corner of the picture. Subsidiary faults are indicated by the curving trend of the rocks along the right side. The photograph will provide detailed information on land use patterns (Dr. R. Colwell, University of California, Berkeley) and fault tectonics (Dr. P. Merifield, Earth Science Res., Inc. and Dr. M. Abdel-Gawad, Rockwell International). Federal agencies participating with NASA on the EREP project are the Departments of Agriculture, Commerce, Interior, the Environmental Protection Agency and the Corps of Engineers. All EREP photography is available to the public through the Department of Interior’s Earth Resources Observations Systems Data Center, Sioux Falls, South Dakota, 57198. Photo credit: NASA
