(Adds details from landing)
ALMATY, March 11 (Reuters) - An American astronaut and two Russians who carried a Sochi Olympic torch into open space landed safely and on time on Tuesday in Kazakhstan, defying bad weather and ending their 166-day mission aboard the International Space Station (ISS).
"We have a landing!" read a huge TV screen at Russia's Mission Control outside Moscow as the descent capsule hit the frozen ground at 0924 (0324 GMT) southeast of the town of Zhezkazgan in central Kazakhstan.
"Safe arrival back on Earth," said a NASA TV announcer while all-terrain rescue and recovery vehicles were shown trundling across a snowy steppe to the Soyuz TMA-10M capsule. "The crew are reported to be in good health," NASA said.
Inside the capsule were former ISS commander Oleg Kotov and flight engineers Sergei Ryazansky and Michael Hopkins from NASA. The trio launched together into space on Sept. 25.
Shortly afterwards, the space travelers were seated in semi-reclined chairs in the deep snow and covered with blue blankets to protect them from strong gusts of wind.
Kotov, the most experienced astronaut in his crew, was shown waving his left hand with a palm black from the soot of the descent capsule, which was charred on re-entry.
Rookie Hopkins smiled as a doctor checked his pulse.
In addition to working on 35 science experiments, Kotov and Ryazansky carried the unlit Olympic torch for the 2014 Winter Olympic Games outside the station during a spacewalk on Nov. 9.
They left behind a small crew headed by Japan's Koichi Wakata, the first Japanese national to command the station. Three more crew members are due to arrive later this month.
Severe weather in Kazakhstan had threatened to delay the Soyuz's landing.
Before their undocking from the ISS, fog and low visibility had prevented airborne rescue and recovery teams from getting to Zhezkazgan, a town about 90 miles (150 km) from the remote landing site on the windswept flatlands, a Russian space industry source said.
But Russian officials decided to go ahead with the landing after reviewing weather forecasts and the status of recovery crews.
"There's a lot of snow on the ground and temperatures are hovering in the single-digits (Fahrenheit)," said NASA mission commentator Dan Huot.
Due to severe weather conditions, it was decided not to set up an inflatable tent for routine medical tests at the landing site. Instead, the crew underwent just quick tests before being flown by helicopters straight to the local Kazakh town of Karaganda, where a formal welcome ceremony would be held.
The U.S.-Russian space partnership so far has not been affected by tensions over Ukraine. The countries lead the 15-nation space station programme.
The $100 billion research complex, which flies about 260 miles (418 km) above Earth, has been permanently staffed by rotating crews of astronauts and cosmonauts since November 2000.
