Until now, the permanent ISS crew has comprised one Russian and one American, on board for six months at a time. Increasing the crew would mean that European and Japanese astronauts could go on longer missions.
Anatoly Perminov, director of the federal space agency Roskosmos, said the lengths of the flights will not change. He said Russia had suggested making them one year, but that the United States did not agree.
