New method ensures better air, water for astronauts
As astronauts embark on increasingly ambitious space missions, scientists have to figure out how to keep them healthy for longer periods far from Earth. Scientists have reported a new method to provide astronauts with better quality air and water, especially for future deep space mission like Mars.
Washington: As astronauts embark on increasingly ambitious space missions, scientists have to figure out how to keep them healthy for longer periods far from Earth. Scientists have reported a new method to provide astronauts with better quality air and water, especially for future deep space mission like Mars.

Current options for testing air and water for contaminants, including microbes and radiation, requires collecting samples and sending them back to Earth for analysis. But for long missions, this approach could take six months before the astronauts get their results. Facundo M. Fernandez, from Georgia Institute of Technology, and colleagues wanted to come up with a system to conduct real-time, sensitive monitoring.
In the new method, they outfitted a kind of Air Quality Monitor (AQM) already used aboard space missions with a device that can vaporise water samples, turning its contents and any contaminants into a gas. Astronauts could also use the same equipment with a modification for testing the air. The system could be used in space or for remote locations right here on Earth.
