This is a Space Shuttle Columbia (STS-65) onboard photo of the second International Microgravity Laboratory (IML-2) in the cargo bay with Earth in the background. Mission objectives of IML-2 were to conduct science and technology investigations that required the low-gravity environment of space, with emphasis on experiments that studied the effects of microgravity on materials processes and living organisms. Materials science and life sciences are two of the most exciting areas of microgravity research because discoveries in these fields could greatly enhance the quality of life on Earth. If the structure of certain proteins can be determined by examining high-quality protein crystals grown in microgravity, advances can be made to improve the treatment of many human diseases. Electronic materials research in space may help us refine processes and make better products, such as computers, lasers, and other high-tech devices. The 14-nation European Space Agency (ESA), the Canadian Space Agency (SCA), the French National Center for Space Studies (CNES), the German Space Agency and the German Aerospace Research Establishment (DARA/DLR), and the National Space Development Agency of Japan (NASDA) participated in developing hardware and experiments for the IML missions. The missions were managed by NASA's Marshall Space Flight Center. The Orbiter Columbia was launched from the Kennedy Space Center on July 8, 1994 for the IML-2 mission.

Astronaut Carl E. Walz, mission specialist, flies through the second International Microgravity Laboratory (IML-2) science module, STS-65 mission. IML was dedicated to study fundamental materials and life sciences in a microgravity environment inside Spacelab, a laboratory carried aloft by the Shuttle. The mission explored how life forms adapt to weightlessness and investigated how materials behave when processed in space. The IML program gave a team of scientists from around the world access to a unique environment, one that is free from most of Earth's gravity. Managed by the NASA Marshall Space Flight Center, the 14-nation European Space Agency (ESA), the Canadian Space Agency (SCA), the French National Center for Space Studies (CNES), the German Space Agency and the German Aerospace Research Establishment (DARA/DLR), and the National Space Development Agency of Japan (NASDA) participated in developing hardware and experiments for the IML missions.

Astronaut Donald Thomas conducts the Fertilization and Embryonic Development of Japanese Newt in Space (AstroNewt) experiment at the Aquatic Animal Experiment Unit (AAEU) inside the International Microgravity Laboratory-2 (IML-2) science module. The AstroNewt experiment aims to know the effects of gravity on the early developmental process of fertilized eggs using a unique aquatic animal, the Japanese red-bellied newt. The newt egg is a large single cell at the begirning of development. The Japanese newt mates in spring and autumn. In late autumn, female newts enter hibernation with sperm in their body cavity and in spring lay eggs and fertilized them with the stored sperm. The experiment takes advantage of this feature of the newt. Groups of newts were sent to the Kennedy Space Center and kept in hibernation until the mission. The AAEU cassettes carried four newts aboard the Space Shuttle. Two newts in one cassette are treated by hormone injection on the ground to simulate egg laying. The other two newts are treated on orbit by the crew. The former group started maturization of eggs before launch. The effects of gravity on that early process were differentiated by comparison of the two groups. The IML-2 was the second in a series of Spacelab flights designed to conduct research by the international science community in a microgravity environment. Managed by the Marshall Space Flight Center, the IML-2 was launch on July 8, 1994 aboard the STS-65 Space Shuttle Orbiter Columbia mission.

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.

STS-94 Commander James D. Halsell, Jr., arrives at the Shuttle Landing Facility aboard a T-38 jet in preparation for the reflight of the Microgravity Science Laboratory-1 mission. Launch is scheduled for July 1, 1997, at 2:37 p.m. EDT. The laboratory was scheduled to fly again with the full complement of STS-83 experiments after that mission was cut short due to a faulty fuel cell. During the scheduled 16-day STS-94 mission, the experiments will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducts combustion, protein crystal growth and materials processing experiments
