NASA AND INTERNATIONAL PARTNERS APPROVE YEAR-LONG SPACE STATION STAY
WASHINGTON
 -- NASA and its international partners have announced an agreement to 
send two crew members to the International Space Station on a one-year 
mission designed to collect valuable scientific data needed to send 
humans to new destinations in the solar system. 
The 
crew members, one American astronaut and one Russian cosmonaut, will 
launch and land in a Russian Soyuz spacecraft and are scheduled to begin
 their voyage in spring 2015. 
The space station serves
 as a laboratory for technological demonstrations and scientific 
research, including experiments that improve understanding of how the 
human body reacts and adapts to the harsh environment of space. Data 
from a year-long expedition also will help inform assumptions about crew
 performance and health, and will help reduce the risks associated with 
future exploration. 
"In order for us to eventually 
move beyond low Earth orbit, we need to better understand how humans 
adapt to long-term spaceflight," said Michael Suffredini, International 
Space Station program manager. "The space station serves as a vital 
scientific resource for teaching us those lessons, and this yearlong 
expedition aboard the complex will help us move closer to those 
journeys." 
During the 12 years of permanent human 
presence aboard the space station, scientists and researchers have 
gained valuable, and often surprising, data on the effects of 
microgravity on bone density, muscle mass, strength, vision and other 
aspects of human physiology. This year-long stay will allow for greater 
analysis of these effects and trends. 
"We have gained 
new knowledge about the effects of spaceflight on the human body from 
the scientific research conducted on the space station, and it is the 
perfect time to test a one-year expedition aboard the orbital 
laboratory," said Julie Robinson, NASA's program scientist for the 
International Space Station. "What we will gain from this expedition 
will influence the way we structure our human research plans in the 
future." 
The expedition also will serve as a test bed 
for future exploration technologies. Those innovative technologies, the 
logistics of the trip to and from the space station and the selection of
 the crew will be announced at a future time.
