The International Space Station is manned by both American and Russian crew, but the only way to reach it is by using Russia's Soyuz spacecraft.
The U.S. is keen to keep the $100billion ISS flying until at least 2024, four years beyond its original target.
However, Mr Rogozin today said that Russia would reject the request, bringing the mission to an end in 2020.
planning that we need the ISS until 2020,' said the official, who is on
the sanctions list of both the U.S. and EU and recently set Russia the
goal of colonising the moon.
'After 2020, we would like to divert these funds to more promising space projects.'
Mr Rogozin - in charge of the country's defence and space industries -
noted that the 'Russian segment of the ISS can exist independently from
the American one, but the American section cannot exist independently of
the Russian one'.
Previously he has suggested that the Americans would have to use a 'trampoline' to get its astronauts into space without Russia.
Rogozin - a hardliner who used to be Russia's ambassador to NATO -
revealed: 'We have definite interest expressed by our American
colleagues on extending the work of the ISS until 2024.
'But the Federal Space Agency, the Russian Academy of Sciences, and the Advanced Research Foundation, are ready now to propose some new strategic aspects, connected with the further development of space exploration after 2020.'
