It's the ultimate ride that very few can, and are willing to take: A paid trip to the International Space Station amounting somewhere between US$ 20-25 million. Telecom mogul Anousheh Ansari spent a week in the ISS in September of 2006, becoming the first female space tourist. She shares her out-of-this-world experience on three videos. Check them out:

As you can see, even the most mundane tasks are challenging in zero gravity. Eating, brushing your teeth and moving about takes months of training along with other conditioning routines.

Did that video revive the astronaut in you? Click on the jump and watch. There's plenty more where that came from.

As US businesswoman Anousheh Ansari prepares to take off from Russia's Baikonur Cosmodrome next month, Russian engineers are busy making modifications. "A woman's organism is different, that's why we need to modify some of the life systems in the capsule," said Nikolai Sevastyanov, head of the RKK Energia space corporation.

The changes are being made mainly to the toilet, and anonymous spokesperson said.

Ansari is taking the place of Japan's Daisuke Enomoto, who failed a medical exam earlier this month. The seat that was specially made for Enomoto will also be replaced.

Ansari will join Russian Mikhail Tyurin and fellow American Michael Lopez-Alegria on the journey. They are currently taking final tests this week at the Star City training centre near Moscow.

35-year-old Internet tycoon Daisuke Enomoto (affectionately known as "Dice-K") has been found physically unfit for space travel by Russian doctors and will not be traveling into orbit next month. Enomoto (above, left) would have paid $20 million USD for a flight to the International Space Station. He has been training for the trip for several months. A self-confessed "cartoon geek," Enomoto's dream was to look down upon the planet dressed as one of his favorite cartoon characters, an ace pilot from an animated Japanese TV series.

Igor Panarin, spokesman for the space agency Roskosmos said "It is not ruled out that after additional measures are taken, he could fly in the future. But this will take time." Anousheh Ansari, a U.S. sponsor of the $10 million X Prize for private spaceflight awarded in 2004 is the most likely candidate to take Enomoto's place on the Soyuz flight.

The first space tourist was US millionaire Dennis Tito in 2001. He was followed  by South African Mark Shuttleworth in 2002 and US businessman Greg Olsen in 2005.
