The IML-1 mission was the first in a series of Shuttle flights dedicated to fundamental materials and life sciences research with the international partners. The participating space agencies included: NASA, the 14-nation European Space Agency (ESA), the Canadian Space Agency (CSA), The French National Center of Space Studies (CNES), the German Space Agency and the German Aerospace Research Establishment (DAR/DLR), and the National Space Development Agency of Japan (NASDA). Dedicated to the study of life and materials sciences in microgravity, the IML missions explored how life forms adapt to weightlessness and investigated how materials behave when processed in space. Both life and materials sciences benefited from the extended periods of microgravity available inside the Spacelab science module in the cargo bay of the Space Shuttle Orbiter. This photograph shows Astronaut Norman Thagard performing the fluid experiment at the Fluid Experiment System (FES) facility inside the laboratory module. The FES facility had sophisticated optical systems for imaging fluid flows during materials processing, such as experiments to grow crystals from solution and solidify metal-modeling salts. A special laser diagnostic technique recorded the experiments, holograms were made for post-flight analysis, and video was used to view the samples in space and on the ground. Managed by the Marshall Space Flight Center (MSFC), the IML-1 mission was launched on January 22, 1992 aboard the Shuttle Orbiter Discovery (STS-42).

This photograph shows activities during the International Microgravity Laboratory-1 (IML-1) mission (STS-42) in the Payload Operations Control Center (POCC) at the Marshall Space Flight Center. Members of the Fluid Experiment System (FES) group monitor the progress of their experiment through video at the POCC. The IML-1 mission was the first in a series of Shuttle flights dedicated to fundamental materials and life sciences research. The mission was to explore, in depth, the complex effects of weightlessness on living organisms and materials processing. The crew conducted experiments on the human nervous system's adaptation to low gravity and the effects on other life forms such as shrimp eggs, lentil seedlings, fruit fly eggs, and bacteria. Low gravity materials processing experiments included crystal growth from a variety of substances such as enzymes, mercury, iodine, and virus. The International space science research organizations that participated in this mission were: The U.S. National Aeronautics and Space Administion, the European Space Agency, the Canadian Space Agency, the French National Center for Space Studies, the German Space Agency, and the National Space Development Agency of Japan. The POCC was the air/ground communication charnel used between astronauts aboard the Spacelab and scientists, researchers, and ground control teams during the Spacelab missions. The facility made instantaneous video and audio communications possible for scientists on the ground to follow the progress and to send direct commands of their research almost as if they were in space with the crew.

iss053e027051 (Sept. 19, 2017) --- Flight Engineer Joe Acaba works in the U.S. Destiny laboratory module setting up hardware for the Zero Boil-Off Tank (ZBOT) experiment. ZBOT uses an experimental fluid to test active heat removal and forced jet mixing as alternative means for controlling tank pressure for volatile fluids. Rocket fuel, spacecraft heating and cooling systems, and sensitive scientific instruments rely on very cold cryogenic fluids. Heat from the environment around cryogenic tanks can cause their pressures to rise, which requires dumping or "boiling off" fluid to release the excess pressure, or actively cooling the tanks in some way.

STS053-09-019 (2 - 9 Dec 1992) --- A medium close-up view of part of the Fluid Acquisition and Resupply Equipment (FARE) onboard the Space Shuttle Discovery. Featured in the mid-deck FARE setup is fluid activity in one of two 12.5-inch spherical tanks made of transparent acrylic. Pictured is the receiver tank. The other tank, out of frame below, is for supplying fluids. The purpose of FARE is to investigate the dynamics of fluid transfer in microgravity and develop methods for transferring vapor-free propellants and other liquids that must be replenished in long-term space systems like satellites, Extended-Duration Orbiters (EDO), and Space Station Freedom. Eight times over an eight-hour test period, the mission specialists conducted the FARE experiment. A sequence of manual valve operations caused pressurized air from the bottles to force fluids from the supply tank to the receiver tank and back again to the supply tank. Baffles in the receiver tank controlled fluid motion during transfer, a fine-mesh screen filtered vapor from the fluid, and the overboard vent removed vapor from the receiver tank as the liquid rose. FARE is managed by NASA's Marshall Space Flight Center (MSFC) in Alabama. The basic equipment was developed by Martin Marietta for the Storable Fluid Management Demonstration. Susan L. Driscoll is the principal investigator.

Aboard the International Space Station (ISS), the Tissue Culture Medium (TCM) is the bioreactor vessel in which cell cultures are grown. With its two syringe ports, it is much like a bag used to administer intravenous fluid, except it allows gas exchange needed for life. The TCM contains cell culture medium, and when frozen cells are flown to the ISS, they are thawed and introduced to the TCM through the syringe ports. In the Cellular Biotechnology Operations Support System-Fluid Dynamics Investigation (CBOSS-FDI) experiment, several mixing procedures are being assessed to determine which method achieves the most uniform mixing of growing cells and culture medium.

The first United States Microgravity Laboratory (USML-1) flew in orbit inside the Spacelab science module for extended periods, providing scientists and researchers greater opportunities for research in materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. In this photograph, Astronaut Bornie Dunbar and Astronaut Larry DeLucas are conducting the Lower Body Negative Pressure (LBNP) experiment, which is to protect the health and safety of the crew and to shorten the time required to readapt to gravity when they return to Earth. When humans go into space, the lack of gravity causes many changes in the body. One change is that fluids normally kept in the lower body by gravity, shift upward to the head and chest. This is why astronauts' faces appear chubby or puffy. The change in fluid volume also affects the heart. The reduced fluid volume means that there is less blood to circulate through the body. Crewmembers may experience reduced blood flow to the brain when returning to Earth. This leads to fainting or near-fainting episodes. With the use of LBNP to simulate the pull of gravity in conjunction with fluids, salt tablets can recondition the cardiovascular system. This treatment, called "soak," is effective up to 24 hours. The LBNP uses a three-layer collapsible cylinder that seals around the crewmember's waist which simulates the effects of gravity and helps pull fluids into the lower body. The data collected will be analyzed to determine physiological changes in the crewmembers and effectiveness of the treatment. The USML-1 was launched aboard the Space Shuttle Orbiter Columbia (STS-50) on June 25, 1992.

S82-28911 (March 1982) --- The L-shaped experiment in the right half of this photo was one of a number of scientific experiments which made the trip for NASA's third space transportation system (STS-3) mission, along with astronauts Jack R. Lousma, pictured, and C. Gordon Fullerton. The experiment, making encore in space (it also flew on the Apollo Soyuz Test Project in 1985), is designed to evaluate the feasibility of separating cells according to their surface electrical charge. It is a forerunner to planned experiments with other equipment that will purify biological materials in the low gravity environment of space. The process of electrophoresis utilizes an electric field to separate cells, and other biological material in fluids without damaging the cells which can then be used in the study of cell biology, immunology and medical research. This photograph was taken with a 35mm camera by Fullerton. Photo credit: NASA

Astronaut Chiaki Mukai conducts the Lower Body Negative Pressure (LBNP) experiment inside the International Microgravity Laboratory-2 (IML-2) mission science module. Dr. Chiaki Mukai is one of the National Space Development Agency of Japan (NASDA) astronauts chosen by NASA as a payload specialist (PS). She was the second NASDA PS who flew aboard the Space Shuttle, and was the first female astronaut in Asia. When humans go into space, the lack of gravity causes many changes in the body. One change is that fluids normally kept in the lower body by gravity shift upward to the head and chest. This is why astronauts' faces appear chubby or puffy. The change in fluid volume also affects the heart. The reduced fluid volume means that there is less blood to circulate through the body. Crewmembers may experience reduced blood flow to the brain when returning to Earth. This leads to fainting or near-fainting episodes. With the use of the LBNP to simulate the pull of gravity in conjunction with fluids, salt tablets can recondition the cardiovascular system. This treatment, called "soak," is effective up to 24 hours. The LBNP uses a three-layer collapsible cylinder that seals around the crewmember's waist which simulates the effects of gravity and helps pull fluids into the lower body. The data collected will be analyzed to determine physiological changes in the crewmembers and effectiveness of the treatment. The IML-2 was the second in a series of Spacelab flights designed by the international science community to conduct research in a microgravity environment Managed by the Marshall Space Flight Center, the IML-2 was launched on July 8, 1994 aboard the STS-65 Space Shuttle Orbiter Columbia mission.

The first United States Microgravity Laboratory (USML-1) was one of NASA's science and technology programs that provided scientists an opportunity to research various scientific investigations in a weightless environment inside the Spacelab module. It also provided demonstrations of new equipment to help prepare for advanced microgravity research and processing aboard the Space Station. The USML-1 flew in orbit for extended periods, providing greater opportunities for research in materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. This photograph shows astronaut Ken Bowersox conducting the Astroculture experiment in the middeck of the orbiter Columbia. This experiment was to evaluate and find effective ways to supply nutrient solutions for optimizing plant growth and avoid releasing solutions into the crew quarters in microgravity. Since fluids behave differently in microgravity, plant watering systems that operate well on Earth do not function effectively in space. Plants can reduce the costs of providing food, oxygen, and pure water as well as lower the costs of removing carbon dioxide in human space habitats. The Astroculture experiment flew aboard the STS-50 mission in June 1992 and was managed by the Marshall Space Flight Center.

Vapor Crystal Growth System developed in IML-1, Mercuric Iodide Crystal grown in microgravity FES/VCGS (Fluids Experiment System/Vapor Crystal Growth Facility). During the mission, mercury iodide source material was heated, vaporized, and transported to a seed crystal where the vapor condensed. Mercury iodide crystals have practical uses as sensitive X-ray and gamma-ray detectors. In addition to their excellent optical properties, these crystals can operate at room temperature, which makes them useful for portable detector devices for nuclear power plant monitoring, natural resource prospecting, biomedical applications, and astronomical observing.

The Interferometer Protein Crystal Growth (IPCG) experiment was designed to measure details of how protein molecules move through a fluid. It was flown on the STS-86 mission for use aboard Russian Space Station Mir in 1998. It studied aspects of how crystals grow - and what conditions lead to the best crystals, details that remain a mystery. IPCG produces interference patterns by spilitting then recombining laser light. This let scientists see how fluid densities - and molecular diffusion - change around a crystal as it grows in microgravity. The heart of the IPCG apparatus is the interferometer cell comprising the optical bench, microscope, other optics, and video camera. IPCG experiment cells are made of optical glass and silvered on one side to serve as a mirror in the interferometer system that visuzlizes crystals and conditions around them as they grow inside the cell. This diagram shows the optical layout. The principal investigator was Dr. Alexander McPherson of University of California, Irvine. Co-investigators are William Witherow and Dr. Marc Pusey of NASA's Marshall Space Flight Center (MSFC).

Two researchers at the National Aeronautics and Space Administration (NASA) Lewis Research Center demonstrate the test equipment they devised to study the transfer of liquid in microgravity onboard the Apollo 14 mission. The test was an early step in developing the ability to transfer liquids from a tanker vehicle to spacecraft in space. Researchers needed to know the tank’s outflow characteristics, the fluid’s behavior when entering new tank, and the effects of accelerations. Others had performed some calculations and analytical studies, but no one had examined the complete transfer from one tank to another in microgravity. The early calculations concluded that the transfer process was impossible without devices to control the liquid and gas. This investigation specifically sought to demonstrate the effectiveness of two different surface-tension baffle designs. The experiment was an entirely closed system with two baffled-tanks. The researchers also built a similar device without the baffles. The experiment was carried onboard the Apollo 14 spacecraft and conducted during the coast period on the way to the moon. The two surface tension baffle designs in the separate tanks were shown to be effective both as supply tanks and as receiver tanks. The liquid transferred within two percent of the design value with ingesting gas. The unbaffled tanks ingested gas after only 12-percent of the fluid had transferred.

Adding microscopic rachets on the surface may passively enable mobility of vapor bubbles and prevent this damage. (Image courtesy of: Techshot, Inc.)

This photograph shows the Skylab Materials Processing Facility (M512) and the Multipurpose Furnace System (M518). This facility, located in the Multiple Docking Adapter, was developed for Skylab,and accommodated 14 different experiments that were carried out during the three marned missions. The abilities to melt and mix without the contaminating effects of containers, to suppress thermal convection and buoyancy in fluids, and to take advantage of electrostatic and magnetic forces and otherwise masked by gravitation opened the way to new knowledge of material properties and processes. This beginning would ultimately lead to the production of valuable new materials for use on Earth.

This is a Space Shuttle Columbia (STS-52) onboard photograph of the United States Microgravity Payload-1 (USMP-1) in the cargo bay. The USMP program is a series of missions developed by NASA to provide scientists with the opportunity to conduct research in the unique microgravity environment of the Space Shuttle's payload bay. The USMP-1 mission was designed for microgravity experiments that do not require the hands-on environment of the Spacelab. Science teams on the ground would remotely command and monitor instruments and analyze data from work stations at NASA's Spacelab Mission Operation Control facility at the Marshall Space Flight Center (MSFC). The USMP-1 payload carried three investigations: two studied basic fluid and metallurgical processes in microgravity, and the third would characterize the microgravity environment onboard the Space Shuttle. The three experiments that made up USMP-1 were the Lambda Point Experiment, the Space Acceleration Measurement System, and the Materials for the Study of Interesting Phenomena of Solidification Earth and in Orbit (MEPHISTO). The three experiments were mounted on two cornected Mission Peculiar Equipment Support Structures (MPESS) mounted in the orbiter's cargo bay. The USMP program was managed by the MSFC and the MPESS was developed by the MSFC.

As NASA plans for future spaceflight programs to low-Earth orbit and beyond, teams of engineers at Kennedy are gaining experience in designing and flying launch vehicle systems on a small scale. Four teams of five to eight members from Kennedy are designing rockets complete with avionics and recovery systems. Launch operations require coordination with federal agencies, just as they would with rockets launched in support of a NASA mission. Photo credit: NASA_Jim Grossmann

ISS036-E-011481 (24 June 2013) --- Russian cosmonaut Fyodor Yurchikhin, Expedition 36 flight engineer, participates in a session of extravehicular activity (EVA) as work continues on the International Space Station. During the six-hour, 34-minute spacewalk, Yurchikhin and Russian cosmonaut Alexander Misurkin (out of frame), Expedition 36 flight engineer, replaced an aging fluid flow control panel on the station's Zarya module as preventative maintenance on the cooling system for the Russian segment of the station. They also installed clamps for future power cables as an early step toward swapping the Pirs airlock with a new multipurpose laboratory module. The Russian Federal Space Agency plans to launch a combination research facility, airlock and docking port late this year on a Proton rocket. Yurchikhin and Misurkin also retrieved two science experiments and installed a new one.
