Gregory Olsen is not an astronaut. He is a 60-year-old businessman from New Jersey where he owned his successful technology company. This week, however, Olsen became the world’s third non-astronaut to pay for a trip into space.

On Monday, the Russian-built Soyuz rocket, carrying Olsen, an American astronaut and a Russian astronaut, docked (对接) at the International Space Station (ISS).

Olsen’s wish has come true. He is the third “space tourist” in four years to travel on a Russian craft to the space station. American Dennis Tito and South African Mark Shuttleworth have both made round trips to the ISS. Going into space is not easy, however. Olsen has worked hard for two years to prepare for it.

The Russian Federal Space Agency offers an ISS trip to anyone who can afford it and pass the necessary training. Olsen reportedly paid $20 million for his trip. The Russian space program has been short of money in recent years and is looking for individuals interested in space travel to _________.

NASA(美国宇航局)has relied on the Russian space program and its Soyuz capsule(太空舱)to transport American astronauts to the ISS since the Columbia space shuttle disaster in 2003. The space shuttle Discovery (发现号宇宙飞船)made a flight earlier this year, but the program stopped halfway because of safety concern. So far, the Russians have not charged the U.S. for trips to the ISS. That may change by the end of the year.

As one of the few space tourists, Olsen focuses his attention on the glory of traveling in space.
