Summary
| Description | 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 Bonnie 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. | |||||
