MOSCOW (Sputnik) - Russian state space corporation Roscosmos is ready to provide a "safety net" to the US partners if Washington's tests of new manned spacecraft are delayed, Roscosmos chief Dmitry Rogozin said on Monday.

"We are ready to provide a safety net to US partners if tests of their new manned spacecraft are delayed. We agree with NASA's proposal to use US and Russian spacecraft in the future… to send mixed international crews to the International Space Station," Rogozin wrote on his Twitter blog.

According to media reports, NASA considers a possibility of signing a contract with Roscosmos so that Russia's Soyuz spacecraft will be used to deliver two US astronauts to the ISS in 2019 and 2020. This option is being considered as a backup plan in case there are any problems with tests of SpaceX's Dragon 2 and Boeing's Starliner spacecraft.
