The pressure is dropping by 2 millimeter of mercury per day
It was registered on January 6 that the atmospheric pressure on the International Space Station started gradually dropping; Russian and American mission control specialists are looking for causes of the fault. On Monday, January 5 the Houston mission control (Texas) warned Russian astronaut Alexander Kaleri and American Michael Foale of the fault, but pointed out the problem was not dangerous for the people's lives.
The International Space Station crew examined equipment in the Russian and American sections of the station, but discovered no malfunctions. During a communication session, Michael Foale mentioned that Alexander Kaleri had examined similar failures on the Mir orbital complex in 2000.
It was on January 1 that drop of pressure was registered on the International Space Station for the first time. NASA official spokesperson James Hartsfield says that the pressure is dropping by 2 millimeter of mercury per day; by Monday the reduction of pressure made up 9 millimeter.
A NASA statement says that the reduction of pressure by 2 millimeter of mercury per day poses no danger for the crew.
However, this is not for the first time that the crew speaks of an incident on the International Space Station. In November 2003, Foale and Kaleri reported they heard some acute metal sound.
It is supposed that some space object has probably hit the International Space Station. However, this version has not been yet confirmed because no showings including the pressure have changed as a result of the incident.
