Russian cosmonauts aboard the ISS reported a smell in the Zvezda module caused by the air conditioning system. This follows from the negotiations of the crew with the Earth, RIA Novosti reports.
“It seems to me that it has become smaller,” cosmonaut Oleg Novitsky said to a specialist at the Mission Control Center near Moscow, answering the question of what the smell is at the present time.
In response, he noted that both air conditioning systems are now turned off, and asked the crew to wipe the area of a possible place for the appearance of the smell with a napkin for further analysis by specialists on Earth, and also, if necessary, turn on the air purification system.
On September 9, a smoke detector and an alarm went off at the Russian Zvezda module. According to cosmonaut Oleg Novitsky, smoke was visible and a smell of burning was felt, and the instruments showed the presence of harmful substances. Astronaut Toma Pesce clarified that the smell of burning was also felt in the American segment of the ISS. As Roskosmos specified, the incident occurred during automatic recharging of batteries. A smoke detector has been triggered and an alarm has been triggered.
Last year, the cosmonauts discovered several cracks in the Zvezda module, as a result of which the tightness was broken, the air pressure at the station was dropping. Subsequently, the cracks were sealed with a sealant.
In July of this year, the pressure in the Zvezda module compartment decreased for several days in a row, including on the eve and on the day of the Nauka module docking. However, the head of Roscosmos, Dmitry Rogozin, said that the decrease in pressure was not connected with this.
