NASA Connection


NASA harnessed what nature already knew and designed an ionization system aboard their Apollo flights. An electronic silver-ion generator – slightly larger than a cigarette pack – was mounted on various locations in the spacecraft. These generators dispersed silver-ions to eliminate bacteria and viruses and provide the astronauts with safe drinking water. They did not want to bring chlorine with them into space.
