NASA and Russia's space agency Roscosmos have signed a long-sought agreement to integrate flights to the International Space Station, allowing Russian cosmonauts to fly on U.S.-made spacecraft in exchange for American astronauts being able to ride on Russia's Soyuz, the agencies said Friday.
"The agreement is in the interests of Russia and the United States and will promote the development of cooperation within the framework of the ISS program," Roscosmos said in a statement, adding it will facilitate the "exploration of outer space for peaceful purposes."
