Science on the International Space Station
Almost as soon as the International Space Station was habitable, people began to use it to study the impact of microgravity and other space effects on daily life. Astronauts on the space station conduct science daily across a wide variety of fields, including human life sciences, biological science, human physiology, physical and materials science, and Earth and space science. Over 600 experiments have been conducted on the space station so far, in over ten years of continuous research. With the completion of station assembly in 2011, space station laboratories can accommodate an unprecedented amount of space-based research.

Scientists from all over the world already are using International Space Station facilities. The scientists are putting their talents to work in almost all areas of science and technology. They are sharing this knowledge to make life on Earth better for people of all nations. We may not know the most important knowledge to be gained from the space station yet, but we do know that some amazing discoveries are on the way! Several recent patents and partnerships already have demonstrated benefits of the public's investment in station research. Accomplishments of early research, such as those identified here, give hints about the value of a fully utilized space station after assembly is complete.

La astronauta Peggy Whitson con el experimento Advanced Astroculture de la planta de soja Air Purification -- A novel air scrubber developed for a spaceflight plant growth chamber is now in widespread use on Earth for food preservation, doctors’ offices, and homes and offices. The scrubber kills 98 percent of airborne pathogens that pass through it.

El experimento de Flujo Capilar a bordo de la estacion espacial Fluid Flow Models -- Capillary flow experiments on the space station produced the first space-validated models describing fluid behavior and may lead to models predicting fluid flows such as groundwater and high-performance wicks used in electronics cooling.

Experimento de JAXA-Granada Crystallization Facilities a bordo de la estacion espacial Duchenne's Muscular Dystrophy -- Large, high-quality crystals of the HQL-79 protein were grown on the space station. These crystals allow researchers to determine the protein's 3-D structure more accurately and to develop a more potent form. This protein is part of a candidate treatment for inhibiting the effects of Duchenne's muscular dystrophy.

El experimento de materiales de la Estacion Espacial Internacional a bordo de la Estacion Espacial Durability of Materials -- Studies of how different materials withstand the harsh space environment provide a better understanding of their durability, with important applications to future spacecraft design. The Naval Research Laboratory and Boeing have used the space station materials test bed to shorten development time for satellite hardware components by as much as 50 percent.

El experimento del Sistema Portatil de Prueba y Desarrollo de Aplicaciones de Laboratorio en un Microprocesador a bordo de la estacion espacial Planetary Contamination Monitoring -- A handheld device used for rapid detection of biological and chemical substances on surfaces on the space station has the potential to monitor the spread of Earth-derived biological material on lunar and planetary surfaces after landings.

El astronauta Leroy Chiao lleva a cabo un experimento con Salzhan Sharipov a bordo de la estacion espacial Ultrasound from a Distance -- Ultrasound training methods developed for spaceflight have been used by the American College of Surgeons to teach ultrasound to surgeons. The methods could be adapted for diagnosis of injuries and illnesses in remote locations on Earth, including rural areas, disaster areas and the battlefield.

Experimento de sistemas de flujo de micro encapsulado en pulso a bordo de la estacion espacial Cancer Treatment Delivery -- The microgravity environment on the space station led the way for better methods of micro-encapsulation on Earth, which is a process of forming micro-balloons containing various drug solutions. Micro-encapsulation provides better drug delivery for several diseases including cancer and diabetes.

El astronauta John Phillips activa un experimento en el trasbordador especial Discovery Vaccine Development -- Studies of Salmonella bacteria on the space station have identified the controlling gene responsible for its increased virulence in microgravity. Finding the controlling gene resulted in the discovery of a candidate vaccine. Salmonella is one of the most common forms of food poisoning and a major cause of childhood death worldwide.
