US to seek Russian help in ISS flights
The United States will have to resort to Russia’s help in delivering its astronauts to the ISS over the next five years, the NASA chief said.
NASA’s Charles Bolden told Congress hearings that Russia’s astronaut delivery services would cost the US $450mln a year.
Washington stopped using shuttles last year and is currently busy designing a new spaceship and a heavy booster rocket.
Should it fail to develop a spacecraft fleet of its own by 2016, NASA will have to continue to seek Russia’s help.
