The Soyuz TMA-16 spacecraft carrying two astronauts successfully undocked from the International Space Station (ISS) on Thursday, a RIA Novosti correspondent reported.

The space capsule carrying Maxim Surayev of Russia and Jeff Williams of the United States from the ISS Expedition 22 is scheduled to land in central Kazakhstan at approximately 14:23 Moscow time [11:23 GMT].

Surayev and Williams have spent over 169 days in orbit.

Work at the ISS will be continued by Russian cosmonaut Oleg Kotov, Japanese astronaut Soichi Noguchi and the U.S.'s Timothy Creamer, until they are joined by Russians Alexander Skvortsov and Mikhail Kornienko, and U.S. astronaut Tracy Caldwell, who are scheduled to depart for the ISS on a Soyuz TMA-18 spacecraft on April 2.
