Atmosphere Revitalization
Subsystem is made up of a number of
elements. All of them are designed to work together to create a safe
and pleasant atmosphere for living and working on Space Station Alpha. The Major Constituent Analyzer sends advisories every twenty minutes. The advisories report the total atmospheric pressure and the percentage of each major gas in Space Station Alpha’s atmosphere. Trace contaminants, if present, are also monitored and reported. The MCA uses mass spectrometry to analyze the air. The Pressure Control Panel controls the atmospheric pressure. If the atmospheric pressure drops, the Pressure Control Panel releases Nitrogen and/or Oxygen into the air. Vacuum Exhaust System allows the astronauts to remove all the air from Space Station Alpha. This only happens if poisonous gases are detected or in case of a fire. (Remember, a fire will not burn without oxygen!). During the exhaust process the astronauts must be in their space suits or using their gas masks “hardwired” to the Atmosphere Control and Supply Subsystem. Cabin Air Fans circulate the gases throughout the space station. Air is also sent to the different Space Station modules through interconnecting tubes. The High Efficiency Particulate Air filters remove dust particles and bacteria from the air. Go Back |
