SPHERES Tether Slosh combines fluid dynamics equipment with robotic capabilities aboard the ISS to investigate automated strategies for steering passive cargo that contain fluids. In space, the fluid fuels used by spacecraft can slosh around in unpredictable ways making space maneuvers difficult. SPHERES Tether Slosh uses two Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) robots tethered to a fluid-filled container covered in sensors to test strategies for safely steering spacecraft such as dead satellites that might still have fuel in the tank.

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 weightlessness 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 is a close-up view of the Drop Physics Module (DPM) in the USML science laboratory. The DPM was dedicated to the detailed study of the dynamics of fluid drops in microgravity: their equilibrium shapes, the dynamics of their flows, and their stable and chaotic behaviors. It also demonstrated a technique known as containerless processing. The DPM and microgravity combine to remove the effects of the container, such as chemical contamination and shape, on the sample being studied. Sound waves, generating acoustic forces, were used to suspend a sample in microgravity and to hold a sample of free drops away from the walls of the experiment chamber, which isolated the sample from potentially harmful external influences. The DPM gave scientists the opportunity to test theories of classical fluid physics, which have not been confirmed by experiments conducted on Earth. This image is a close-up view of the DPM. The USML-1 flew aboard the STS-50 mission on June 1992, and was managed by the Marshall Space Flight Center.

The crew patch for NASA's STS-83 mission depicts the Space Shuttle Columbia launching into space for the first Microgravity Sciences Laboratory 1 (MSL-1) mission. MSL-1 investigated materials science, fluid dynamics, biotechnology, and combustion science in the microgravity environment of space, experiments that were conducted in the Spacelab Module in the Space Shuttle Columbia's cargo bay. The center circle symbolizes a free liquid under microgravity conditions representing various fluid and materials science experiments. Symbolic of the combustion experiments is the surrounding starburst of a blue flame burning in space. The 3-lobed shape of the outermost starburst ring traces the dot pattern of a transmission Laue photograph typical of biotechnology experiments. The numerical designation for the mission is shown at bottom center. As a forerunner to missions involving International Space Station (ISS), STS-83 represented the hope that scientific results and knowledge gained during the flight will be applied to solving problems on Earth for the benefit and advancement of humankind.

Helms, payload commander, and payload specialist Jean-Jacques Favier, representing the French Space Agency (CNES), insert a test container into the Bubble Drop Particle Unit (BDPU) in the Life and Microgravity Spacelab (LMS-1) Science Module aboard the Space Shuttle Columbia. The fluid in the chamber is heated and the fluid processes are observed by use of three internal cameras mounted inside the BDPU. Investigations in this facility will help characterize interfacial processes involving either bubbles, drops, liquid columns or liquid layers.

In this photograph, astronaut Eugene Trinh, a payload specialist for this mission, is working at the Drop Physics Module (DPM), and mission specialist Carl Meade is working on the experiment at the Glovebox inside the first United States Microgravity Laboratory (USML-1) Science Module. The USML-1 was one of NASA's missions dedicated to scientific investigations in a microgravity environment inside the Spacelab module. Investigations aboard the USML-1 included: materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. The DPM is dedicated to the detailed study of the dynamics of fluid drops in microgravity. The Glovebox offers experimenters new capabilities and technologies in microgravity with a clean working space and minimizes contamination risks to both Spacelab and experiment samples. Payload specialists are professional scientists or engineers whose only assignment on a space flight is to carry out scientific and technological experiments. Their specific training for a space flight is usually limited to a short period of learning how to live and work in weightlessness. Mission Specialists are both professional scientists and career astronauts. Thus they are a link or bridge between the other crew members, and combine the functions of resident maintenance engineers, in-space counterparts of flight engineers in aircraft, and fully qualified scientists. The USML-1 flew aboard the STS-50 mission on June 1992, and was managed by the Marshall Space Flight Center.

Space Shuttle Columbia (STS-50) launched into history carrying crew of seven and its payload was comprised of the US Microgravity Laboratory 1 (USML-1).The USML-1 was one of NASA's missions dedicated to scientific investigations in a microgravity environment inside the Spacelab module. Investigations aboard the USML-1 included: materials science, fluid dynamics, biotechnology (crystal growth), and combustion science. Managed by Marshall Space Flight Center, the STS-50 mission was plarned for a 13-day duration, the mission ended with 14 days in space, the longest Shuttle mission to date.

The first United States Microgravity Laboratory (USML-1) provided scientific research in materials science, fluid dynamics, biotechnology, and combustion science in a weightless environment inside the Spacelab module. This photograph is a close-up view of the Glovebox in operation during the mission. The Spacelab Glovebox, provided by the European Space Agency, offers experimenters new capabilities to test and develop science procedures and technologies in microgravity. It enables crewmembers to handle, transfer, and otherwise manipulate materials in ways that are impractical in the open Spacelab. The facility is equipped with three doors: a central port through which experiments are placed in the Glovebox and two glovedoors on both sides with an attachment for gloves or adjustable cuffs and adapters for cameras. The Glovebox has an enclosed compartment that offers a clean working space and minimizes the contamination risks to both Spacelab and experiment samples. Although fluid containment and ease of cleanup are major benefits provided by the facility, it can also contain powders and bioparticles; toxic, irritating, or potentially infectious materials; and other debris produced during experiment operations. The facility is equipped with photographic/video capabilities and permits mounting a microscope. For the USML-1 mission, the Glovebox experiments fell into four basic categories: fluid dynamics, combustion science, crystal growth, and technology demonstration. The USML-1 flew aboard the STS-50 mission in June 1992.

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.

The module will be left behind so it can be used for microgravity experiments in fluid physics, materials science, biology and biotechnology. Space shuttle Discovery will deliver its payload to the station on the STS-133 mission. Launch is targeted for Nov. 1 at 4:33 p.m. EDT. Photo credit: NASA_Jack Pfaller

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 is a close-up view of the Astroculture experiment rack in the middeck of the orbiter. The Astroculture 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 USML-1 flew aboard the STS-50 mission on June 1992 and was managed by the Marshall Space Flight Center.

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.

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).

The USML-1 flew in orbit for extended periods, providing greater opportunities for research in materials science, fluid dynamics, biotechnology, and combustion science. In this photograph, astronaut Carl Meade is reviewing the manual to activate the Generic Bioprocessing Apparatus (GBA) inside the Spacelab module. The GBA for the USML-1 mission was a multipurpose facility that could help us answer important questions about the relationship between gravity and biology. This unique facility allowed scientists to study biological processes in samples ranging from molecules to small organisms. For example, scientists would examine how collagen, a protein substance found in cornective tissue, bones, and cartilage, forms fibers. In microgravity, it might be possible to alter collagen fiber assembly so that this material could be used more effectively as artificial skin, blood vessels, and other parts of the body. The USML-1 was managed by the Marshall Space Flight Center and waslaunched aboard the Space Shuttle Orbiter Columbia (STS-50) on June 25, 1992.

The Space Shuttle was designed to carry large payloads into Earth orbit. One of the most important payloads is Spacelab. The Spacelab serves as a small but well-equipped laboratory in space to perform experiments in zero-gravity and make astronomical observations above the Earth's obscuring atmosphere. In this photograph, Payload Specialist, Ulf Merbold, is working at Gradient Heating Facility on the Materials Science Double Rack (MSDR) inside the science module in the Orbiter Columbia's payload bay during STS-9, Spacelab-1 mission. Spacelab-1, the joint ESA (European Space Agency)/NASA mission, was the first operational flight for the Spacelab, and demonstrated new instruments and methods for conducting experiments that are difficult or impossible in ground-based laboratories. This facility performed, in extremely low gravity, a wide variety of materials processing experiments in crystal growth, fluid physics, and metallurgy. The Marshall Space Flight Center had overall management responsibilities.

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. This photograph shows Astronaut Larry De Lucas wearing a stocking plethysmograph during the mission. Muscle size in the legs changes with exposure to microgravity. A stocking plethysmograph, a device for measuring the volume of a limb, was used to help determine these changes. Several times over the course of the mission, an astronaut will put on the plethysmograph, pull the tapes tight and mark them. By comparing the marks, changes in muscle volume can be measured. The USML-1 was launched aboard the Space Shuttle Orbiter Columbia (STS-50) on June 25, 1992.

This is a photograph of the Spacelab module for the first United States Microgravity Laboratory (USML-1) mission, showing logos of the Spacelab mission on the left and the USML-1 mission on the right. The USML-1 was one part of a science and technology program that opened NASA's next great era of discovery and established the United States' leadership in space. From investigations designed to gather fundamental knowledge in a variety of areas to demonstrations of new equipment, USML-1 forged the way for future USML missions and helped prepare for advanced microgravity research and processing aboard the Space Station. Thirty-one investigations comprised the payload of the first USML-1 mission. The experiments aboard USML-1 covered five basic areas: fluid dynamics, the study of how liquids and gases respond to the application or absence of differing forces; crystal growth, the production of inorganic and organic crystals; combustion science, the study of the processes and phenomena of burning; biological science, the study of plant and animal life; and technology demonstrations. The USML-1 was managed by the Marshall Space Flight Center and launched aboard the Space Shuttle Orbiter Columbia (STS-50) on June 25, 1992.

A wide-angle view of the floor of the Space Station Processing Facility. The floor is filled with racks and hardware for processing and testing the various components of the International Space Station (ISS). At center left is the Zenith-1 (Z-1) Truss, the cornerstone truss of the Space Station. The Z-1 Truss was officially turned over to NASA from The Boeing Co. on July 31. It is scheduled to fly in Space Shuttle Discovery's payload pay on STS-92 targeted for launch Oct. 5, 2000. The Z-1 is considered a cornerstone truss because it carries critical components of the Station's attitude, communications, thermal and power control systems as well as four control moment gyros, high and low gain antenna systems, and two plasma contactor units used to disperse electrical charge build-ups. The Z-1 truss and a Pressurized Mating Adapter (PMA-3), also flying to the Station on the same mission, will be the first major U.S. elements flown to the ISS aboard the Shuttle since the launch of the Unity element in December 1998. The large module in the upper right hand corner of the floor is the U.S. Lab, Destiny. Expected to be a major feature in future research, Destiny will provide facilities for biotechnology, fluid physics, combustion, and life sciences research. It is scheduled to be launched on mission STS-98 (no date determined yet for launch)

The laboratory module in the cargo bay of the Space Shuttle Orbiter Columbia was photographed during the Spacelab Life Science-1 (SLS-1) mission. SLS-1 was the first Spacelab mission dedicated solely to life sciences. The main purpose of the SLS-1 mission was to study the mechanisms, magnitudes, and time courses of certain physiological changes that occur during space flight, to investigate the consequences of the body's adaptation to microgravity and readjustment to Earth's gravity, and to bring the benefits back home to Earth. The mission was designed to explore the responses of the heart, lungs, blood vessels, kidneys, and hormone-secreting glands to microgravity and related body fluid shifts; examine the causes of space motion sickness; and study changes in the muscles, bones and cells. The five body systems being studied were: The Cardiovascular/Cardiopulmonary System (heart, lungs, and blood vessels), the Renal/Endocrine System (kidney and hormone-secreting organs), the Immune System (white blood cells), the Musculoskeletal System (muscles and bones), and the Neurovestibular System (brain and nerves, eyes, and irner ear). The SLS-1 was launched aboard the Space Shuttle Orbiter Columbia (STS-40) on June 5, 1995.

STS050-S-001 (January 1992) --- Designed by the flight crew, the insignia for the United States Microgravity Laboratory (USML-1), captures a space shuttle traveling above Earth while trailing the USML banner. The orbiter is oriented vertically in a typical attitude for microgravity science and in this position represents the numeral 1 in the mission's abbreviated title. This flight represents the first in a series of USML flights on which the primary objective is microgravity science, planned and executed through the combined efforts of the United States of America's government, industry and academia. Visible in the payload bay are the Spacelab module, and the extended duration orbiter "cryo" pallet which will be making its first flight. The small g and Greek letter mu on the Spacelab module symbolize the microgravity environment being used for research in the areas of materials science and fluid physics. The large block letter U extends outside the patch perimeter, symbolizing the potential for the experiments on this flight to expand the current boundaries of knowledge in microgravity science. The Stars and Stripes of the USML block letters and the United States landmass in the Earth scene below reflect the crew's pride in the United States origin of all onboard experiments. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the forms of illustrations by the various news media. When and if there is any change in this policy, which is not anticipated, the change will be publicly announced. Photo credit: NASA
