Cleanrooms aren’t just in American space missions; they are used by nations around the world sending spacecraft beyond the skies of Earth.  The European Space Agency is working on a new project which will send several devices to Mars to track the temperature.

 

In order to work on these devices headed for Mars, ESA technicians must don a protective suit and use an air shower before entering the cleanroom.  Stakes are high on a mission such as this, and contamination has the potential to cause a myriad of problems.

 

Cleanrooms provide a controlled environment for equipment to be worked on and can help ensure that tiny organisms don’t get a free ride to Mars.  To learn more about this mission, check out this article at AstroBiology, and to learn more about cleanrooms visit this site.
