The men are slated to return to Earth in December.Previously, Russia flew three cosmonauts, with the remaining three positions filled by a combination of European, Japanese, Canadian and US astronauts, who are trained and overseen by NASA.. Ryazanskiy, 42, spent five-and-a-half China vacuum compressed bag Manufacturers months aboard the station in 2013-2014.The extra astronaut will effectively double the amount of time for research, program manager Kirk Shireman said at a station conference last week. Both spaceships have room for a fourth seat, bumping the station’s overall crew size to seven once Russia returns to full staffing. EDT (2154 GMT) as the $100 billion research outpost sailed about 250 miles (400 km) over Germany, a NASA TV broadcast showed.

 

NASA does not oversee the Russian staff, which was reduced to two in April until a long-delayed research module joins the station next year.Bresnik, 49, last flew on the space shuttle in 2009 during a space station assembly mission.The men will join two NASA astronauts and a Russian cosmonaut already aboard the station, a project of 15 nations.The men will join two NASA astronauts and a Russian cosmonaut already aboard the station, a project of 15 nations.Strapped inside the capsule, which blasted off aboard a Soyuz rocket from Kazakhstan six hours earlier, were Randy Bresnik, with the US National Aeronautics and Space Administration; Sergey Ryazanskiy, with the Russian space agency Roscosmos; and Italy's Paolo Nespoli, with the European Space Agency.By the end of next year, NASA intends to begin flying astronauts aboard space taxis under development by SpaceX and Boeing.NASA is using the station to prepare for human missions to the moon and Mars and to stimulate commercial space transportation, pharmaceutical research, manufacturing and other businesses. Nespoli, 60, is making his third space flight, having previously served on both space shuttle and space station crews.

 

Their arrival means the US space agency now has four crew members instead of three available for medical experiments, technology demonstrations and other research aboard the station, the US space agency said. A new crew arrived at the International Space Station on Friday, giving NASA for the first time four astronauts to boost US research projects aboard the orbiting laboratory.Their arrival means the US space agency now has four crew members instead of three available for medical experiments, technology demonstrations and other research aboard the station, the US space agency said.The agency also conducts physics, astronomy and Earth science investigations aboard the outpost, which has been staffed by rotating crews of astronauts and cosmonauts since 2000.A Russian Soyuz capsule carrying three spaceflight veterans slipped into a docking port aboard the station at 5:54 p
