A Soviet space capsule that orbited the Earth with a mannequin and a live dog as a test run for the first manned space flight is being auctioned in New York.
The Vostok 3KA-2 is a twin of the spacecraft that carried cosmonaut Yuri Gagarin on his first mission into space on April 12, 1961.
It made a successful orbit in about two hours and re-entered the Earth's atmosphere 18 days before the manned mission.
Sotheby's auction house is selling it on April 12, the 50th anniversary of the manned mission. It is estimated to fetch between £1 million and £6 million.
The instrumentation in the capsule's interior has been stripped for security reasons.
Sotheby's said the anonymous owner bought the capsule years ago.
