Spacelab Life Sciences 1: First Space Laboratory Dedicated to Life Sciences Research
NASA, Lyndon B. Johnson Space Center, 1989 - Government publications - 44 pages
The main purpose of the SLS-1 mission is to study the mechanisms, magnitudes, and time courses of certain physiological changes that occur during space flight and to investigate the consequences of the body's adaptation to microgravity and readjustment to 1-g. The SLS-1 investigations 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. Procedures and equipment for space biomedical investigations are also tested. These tests are essential to developing an effective and efficient laboratory for life sciences research on Space Station Freedom.

Page 4 - Sputnik 2, was launched carrying the first living creature into orbit, a dog named Laika (Figure 1). Laika was carried in a pressurized compartment in the satellite, but after a few days she died. Sputnik 2 reentered the Earth's atmosphere on April 14, 1958. While these animals were in space, instruments monitored various physiological responses as the animals experienced the stresses of launch, reentry, and the weightless environment. As scientists gained more experience with these...
Page 36 - Life sciences research in space demands heavy crew involvement as expert investigators, test subjects, and laboratory technicians. Crew members draw and process blood samples, record their own physiological symptoms, set up and participate in a variety of experiments, tend plant and animal experiments, and carry on their work much as they do in laboratories on the ground. The...

During these early missions, scientists began to learn about human responses to microgravity. However, the small Mercury, Gemini, and Apollo spacecraft had little room for research equipment.
