Deputy Prime minister Dmitry Rogozin announced Tuesday that Moscow forbids the US to continue to use Russian engines for launching American rockets. Russian-made RD-180 engines are fitted on the US Air Force’s Atlas V active expendable launch system rockets. Anticipating this Russian step, Washington went shopping in recent weeks for a substitute, but did not find one. Some US ICBMs are therefore idle. Washington was also informed that the use of the international space station by US astronauts would be withdrawn after 2020.
