WASHINGTON, April 18, 2014 /PRNewswire-USNewswire/ -- When the SpaceX-3 cargo resupply mission launched to the International Space Station April 18, an experiment designed by Durham Veterans' Affairs Medical Center of Durham, N.C., was among the cargo headed to space.
The experiment, APEX-02-2, investigates how cells adapt to the space environment using the model eukaryotic organism, Saccharomyces cerevisiae (yeast). Researchers will be able to identify factors associated with how genetic information is transferred and the associated signaling pathways that are involved in microbial growth and physiological responses in the space environment.
SpaceX-3 is NASA's third contracted resupply mission to the space station by U.S. company SpaceX of Hawthorne, Calif. SpaceX's Dragon spacecraft launched atop the company's Falcon rocket from the Cape Canaveral Air Force Station in Florida at 4:58 p.m. EDT.
SpaceX developed its Dragon capsule, the only cargo spacecraft currently servicing the space station with the capability to return cargo back to Earth, with NASA and now successfully has completed three missions to the orbiting outpost. Expedition 39 crew members captured the SpaceX-3 Dragon using the station's robotic arm at 7 a.m. Wednesday, April 16. The capsule is scheduled to remain attached to the station unit May 18. It then will return to Earth and splash down in the Pacific Ocean, off the coast California. It will return samples from scientific investigations currently underway aboard the space station.
The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has had continuous human occupation since November 2000. In that time it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.
