"The extravehicular activity according to the Russian program is scheduled for August 10. The exit is planned for 17:14 Moscow time [14:14 GMT] and it will end at 23:48," the spokesperson told RIA Novosti.
According to earlier information, cosmonauts Gennady Padalka and Mikhail Kornienko will polish the windows of the ISS on the outside.
The date of the extracurricular activity has been changed several times following the failure of an earlier Progress M-27M spacecraft. A subsequent Russian Progress-M28M cargo spacecraft delivered the necessary supplies July 5.
In April, the previous spacecraft burned in the Earth's atmosphere over the Pacific Ocean after an improper separation from the Soyuz carrier rocket, caused by fuel leaks.
