Agnirva Space Premier League - Expedition #31496: Battling Biofilms in Space: Vandal Voyagers II and Water System Protection

In space, even microscopic invaders like biofilms can pose major threats to life support systems. The Vandal Voyagers II experiment, led by Dr. Matthew Bernards from the University of Idaho, aimed to test innovative coatings that resist biofilm formation in spacecraft water systems.

Biofilms are colonies of microorganisms that adhere to surfaces and form slimy layers. In water systems aboard spacecraft, these biofilms can clog filters, corrode equipment, and harbor harmful bacteria. Traditional cleaning methods don’t always work in space, making prevention crucial.

Vandal Voyagers II tested several advanced coatings to see which materials best resist microbial attachment in microgravity. These coatings could prevent biofilm growth on pipes, tanks, and other water system components. The experiment spanned Expeditions 73 and 74 on the ISS and offered valuable insights into long-duration mission hygiene.

If successful, these coatings could be used in future spacecraft, space stations, and even Earth-based water systems, reducing maintenance costs and improving safety.
