Who will win the space race?

The space race is back on but who will win.

The journey marked Russia's return to space tourism after a decade-long pause that saw the rise of competition from the US.

Three Japanese tourists spent 12 days on the International Space Station, documenting their daily lives on the internet.

The 46-year-old billionaire explained to his 1 million followers how to brush teeth and go to the toilet in space. In one of the videos, he explained how to relieve oneself on the International Space Station.

A live broadcast from the landing site of the Soyuz capsule is shown at Russia's mission control centre. The picture was taken by Alexander Nemenov.

He showed a handheld funnel astronauts use to suck urine away.

He showed his followers how to drink tea and sleep in zero gravity in other videos.

The three space travellers joined a seven-team crew who were doing space biology and physics research.

Maezawa is going to take eight people with him on a mission around the moon. He and his assistant are the first private Japanese citizens to visit space since 1990.

Their return from space caps a banner year for private space travel.

Russia is eager to defend its market after billionaires Musk, Bezos and Richard Branson made breakthrough commercial tourism flights this year.

Russia has sent tourists to space before. Since 2001, seven tourists have been taken to the International Space Station, one of them twice.

Alexander Misurkin, Yusaku Maezawa, and Yozo Hirano are training for their space trip.

Guy Laliberte was dubbed the first clown in space in 2009.

In October, Russia launched its first untrained cosmonauts into space, delivering a Russian actress and a director to the International Space Station, where they filmed scenes for a movie.

Russia had a monopoly on supplying the International Space Station after the retirement of the space shuttle in 2011.

tourist flights were effectively ended by the purchase of all Soyuz launch seats by Nasa for $90m per spot. Last year, the first astronauts were delivered to the International Space Station.

Russia's monopoly on flights was stripped away by Nasa, which began purchasing flights from SpaceX.

The cost of tickets to space for tourists has not been disclosed, but Space Adventures has indicated they are in the range of $50m to $60m.

The company plans to grow its space tourism business, already having two Soyuz rockets for such trips.
