Russia aims to build its own orbiting space base when the International Space Station (ISS) is no longer serviceable - to launch missions to the Moon and Mars.
The ISS has been under constant occupation by astronauts since November 2000 but due to structural fatigue needs to be decommissioned by 2030.
After this Roscosmos plans to take the modules it built for the ISS and use them as the base parts of its new orbiting space station - which will take a decade to build.
The Russian agency says the aim would be to use the new space station as a place to assemble and refuel spacecraft before launching them further into the solar system.

Dmitry Rogozin, head of Roscosmos, said the platform was 'for exploring far-out space' and would include flights to Mars, the Moon and asteroids.
'We're going to put together spacecraft in orbit for flights to Mars, the moon, and to asteroids, because it's very difficult and challenging to bring such an entire construction up from Earth,' Rogozin said.
He saw Russia was open to the idea of working with other countries on their new space station - which would double as a refuelling station and assembly point.
Russia plans to send a crewed mission to the Moon by 2028 - four years after the US Artemis mission will put the first woman and next man on the lunar surface.
Moscow also hopes to send cosmonauts to Mars using its Angara heavy lift rockets - currently under development - but hasn't set a date.
The announcement of the new Russian space station comes as NASA moves a step closer to ending its reliance on Roscosmos rockets to send astronauts to the ISS.
Since NASA ended the Space Shuttle programme in 2011 Russia has been the only country able to take astronauts to and from the ISS - using its Soyuz rockets.

NASA has paid Roscosmos to take its astronauts to the space station since 2011 but the long-standing relationship is expected to end soon thanks to SpaceX.
Elon Musk's space firm is expected to launch two NASA astronauts from US soil for the first time since 2011 this weekend on top of its Falcon 9 rocket.
This move may be part of the reason behind Russia's drive to expand its space programme further into the solar system.
Rogozin says the country should start work preparing for its own space station as soon as possible due to the fact it will take a decade to build.
'As a country that has always been a leader in the creation of orbital stations, Russia should immediately begin work on creating a new one,' he told Radio Komsomolskaya Pravda in an interview on the countries space plans.
The country hasn't said whether the space station would be occupied like the ISS or fully automated to assemble and refuel spacecraft.
Rogozin also said Roscosmos is 'considering the possibility of creating a winged manned spacecraft for flights to orbital stations,' to
