The crew of the International Space Station (ISS) has been alerted to a little smoke coming from the Russian module, NASA website reported Wednesday.

The smoke was coming out of a vent in the Zvezda Service Module, according to the US space agency.

The Russian segment's ventilation system was isolated by flight controllers at the mission control center in Houston, RIA Novosti report.

"Expedition 40 Commander Steve Swanson reported that the smoke quickly subsided and the crew was not in any danger,"NASA added.

Russian flight controllers determined that the smoke was most likely caused by a heater for the Russian segment's water reclamation unit used for cooking.
