Fresh off a trip to the International Space Station in September, U.S. entrepreneur Anousheh Ansari dropped by a New Mexico airport on Saturday and liked what she saw — a sprawling science fair that attracted space enthusiasts and entrepreneurs.

The two-day fair — the second annual X Prize Cup — in Las Cruces was what she and her husband envisioned when they donated millions of dollars two years earlier to the nonprofit X Prize Foundation, which sponsors contests to encourage space technology innovation.

"Our vision was this," said Ansari, who became the world's first female space tourist when she paid about $20 million US to fly aboard a Russian Soyuz rocket in September.

The X Prize Cup is composed of various competitions with prize money totalling as much as $2 million US. It is an offshoot of the 2004 Ansari X Prize that awarded $10 million to Burt Rutan, who successfully launched a rocket carrying a person into suborbital space.

Ansari, an Iranian-American telecommunications entrepreneur, said she anticipates routine tourist space travel will become a reality in about 25 years.

In the meantime, New Mexico is angling to develop a space industry. About 80 kilometres north of Las Cruces, in Upham, state officials have created Spaceport America, the future home of British billionaire Richard Branson's Virgin Galactic space tourism company.

A look around the booths at the X Prize Cup competition suggests Ansari is not the only one thinking that way. One company pitched a lunar resort. Most of the weekend's competitions were designed to spark new ideas and technologies that can be used in private space travel and for NASA.

Phil West, a NASA spokesman, said the government-run space agency offered prize money for a lunar lander in part to generate new ideas.

Armadillo Aerospace of Mesquite, Texas, spent much of the afternoon trying to win a $350,000 NASA-funded prize for successfully launching and landing a lunar lander. The lander faltered in the first two attempts — in one case landing off a designated pad.

The final try on Saturday afternoon ended when the small craft lifted off the launch pad and crashed in the nearby rugged desert.

Ian Murphy, an X Prize spokesman, said faltering attempts are nothing out of the ordinary in the space business.
