Anousheh Ansari was greeted with red roses as she emerged from a Russian Soyuz capsule that touched down in Kazakhstan this morning.
"I want to tell Iranian women that they can achieve whatever they want," she told journalists. "They are all brave women, and so they can achieve whatever they think and dream about."
The capsule was also carrying two professional astronauts back from the International Space Station, Russian Pavel Vinogradov and American Jeff Williams.
"I looked out of my window and I saw the grassland and I knew we were on the Earth, it felt good," Williams said. "It wasn't too difficult. I actually expected more of a bump on the ground, but it wasn't bad at all."
Earlier, Ansari said her trip had been "magnificent" and that she hoped to do it again one day.
The Iranian-born U.S. businesswoman is thought to have paid about $20 million for 11 days in space.

RFE/RL has provided extensive coverage of these important issues and of efforts to cope with them.
