The Russian M-24M cargo resupply spacecraft, will undock from the International Space Station (ISS) on October 27, a spokesman for Russia's space agency, Roscosmos, told RIA Novosti Tuesday.

"The undocking is scheduled for 9:38 Moscow time [06:38 GMT] October 27," the source said, adding that upon leaving the ISS, the cargo spacecraft would be taking part in a scientific experiment until November 20 to study the impact of its engines on the plasma in the Earth's ionosphere.

The Progress M-24M space freighter that was launched from the Baikonur space center in Kazakhstan earlier in July has delivered fuel, oxygen, and food, as well as equipment for scientific experiments and parcels for the cosmonauts.
