A Russian Soyuz spacecraft containing an international trio of astronauts who oversaw the final assembly stage of a $100 billion space station landed safely on Kazakhstan's steppe on Wednesday. Russian Oleg Kotov, NASA's Timothy Creamer and Japan's Soichi Noguchi arrived near the town of Zhezkazgan as planned, at 0725 Moscow time (0325 GMT), Russia's Mission Control outside Moscow said. "There has been a soft landing," the announcer said to applause from observers in the gold-lined, Soviet-era Mission Control building, according to a report of Reuters.
