The first Dane in space has arrived at the International Space Station (ISS) as part of a three-man team, bringing with him a set of custom-made Lego figurines, the Russian space agency said.

Danish astronaut Andreas Mogensen accompanied by Russian cosmonaut Sergei Volkov and Aidyn Aimbetov from Kazakhstan take the total number of people on the ISS to nine, for the first time since 2013, according to the European Space Agency.

The trio blasted off aboard a Soyuz rocket from the Baikonur cosmodrome on Wednesday, but the trip lasted two days instead of the usual fast-track six hours after the ISS raised its orbit to avoid space debris.

Mr Volkov is expected to remain in orbit until March 2016, along with Russian cosmonaut Mikhail Kornienko and US astronaut Scott Kelly who are already aboard the ISS.

Accompanied by veteran Russian cosmonaut Gennady Padalka, first-time flyers Mr Aimbetov and Mr Mogensen will return to Earth next week after 10 days on the station.

Mr Aimbetov, who replaced British singer Sarah Brightman after she pulled out of the mission in June, is the third astronaut from Kazakhstan, which hosts Russia's cosmodrome.

The trio led by Mr Padalka, who has been in orbit since June, are set to leave the orbiting space station on September 12.

Upon his return to Earth, Mr Padalka will have spent 878 days — or roughly 2.5 years — in space, setting a record for spending the longest time in space.

Russia is the only country still sending its own craft to the ISS after NASA ended its space shuttle program in 2011 and turned to private firms to fly supply missions there.
