The process proved to be not only successful in space - it can also be used on Earth in vertical farms and urban plant factories. As a result, NASA scientists, working closely with the private sector, developed a fertilizer that would release its nutrients over a specific amount of time. Traditional fertilizer can’t be used on plants in space, as they’re not grown with traditional soil. Practical benefits for those on Earth have come from studying all these various forms of life in space. What we learn could influence our approach to growing different plant types in the future. So we examine their RNA to see how it’s giving directions and signals, and how that differs from the way plants behave on Earth.” Many types of plants are grown on the station, from flowering plants to leafy greens to vegetables. They no longer have a gravity signal for their root structure. They don't know which way is down anymore. Regarding plants, Buchli says: “Plants develop differently in microgravity.

And the genetic changes from one generation to another are easy to track.” We can trace the actual development of an organism from conception to birth to adulthood and old age. “Fruit flies multiply so quickly, we can observe several generations at one time. She explains how studying multi generational organisms can have a big impacts on our understanding of both animal and plant biology in space. Jennifer Buchli is the deputy chief scientist for the International Space Station Program Research Office at NASA’s Johnson Space Center. Why? This matters to scientists who are studying the effect of microgravity on bone loss. As such Roundworms were exposed to a microscopic obstacle course to study their unusual muscle strength, while Zebrafish have helped researchers develop countermeasures for muscle weakness.Īnother fish, the Japanese medaka, have helped improve our understanding of the mechanisms behind organ tissue changes.Īnd of course, one of the most common space travelers, the rodent, was found to be more physically active in space than their Earth-bound counterparts in one experiment. What can we learn from these amazing creatures that might help keep astronauts safer in extreme environments?Īstronauts exercise two hours a day and closely monitor their diet, however the loss of muscle mass that occurs in space is still a serious obstacle that researchers are working to overcome.

The tardigrade, or Water Bear, is well known to possess genes that can withstand extreme hot and cold temperatures, dehydration and radiation. Since many share similar cells, tissues and other organic structures to humans, each is studied for what they can reveal to help astronauts withstand the rigors of long-range space travel. To view the streaming station video on Feb.Animals that fly in the air, animals that swim, squirt and float in water, animals that, creep, crawl, walk and run on land – all are being studied to learn how they react, and adapt to microgravity conditions. Station residents have conducted important scientific experiments and gathered data to help assist future missions. Twenty-two crews have lived aboard the orbiting laboratory since 2000, including the current crew of five. Construction began in 1998 and will be completed in 2010. The station is a unique partnership between the space agencies of the United States, Canada, Europe, Japan and Russia. When the space shuttle is docked to the station, the stream will include video and audio of those activities. During "loss of signal" periods, Internet viewers may see a test pattern. Television from the station is available only when the complex is in contact with the ground through its high-speed communications antenna and NASA's Tracking and Data Relay Satellite System. The new in-cabin streaming video includes audio of communications between Mission Control and the astronauts, when available. Since March 2009, NASA has provided streaming video online of Earth and the station's exterior as the laboratory complex orbits 220 miles above Earth at 17,500 miles per hour. 1 and will be available during all crew duty hours. HOUSTON - NASA soon will provide Internet viewers an inside look at astronauts working in space by streaming video live from the International Space Station's laboratories.
