Cleaning Slime in Microgravity

Onboard the International Space Station, astronauts use disposable cleaning wipes to clean down surfaces on the station, a task which takes up 2-4 hours every Saturday morning. In this first of its kind experiment from the ISSET Launch Prize virtual program, a team from the Minerva Virtual Academy designed an experiment to use reusable antimicrobial cleaning slime as a new, sustainable method for cleaning the ISS. The team hope to identify how effective this agent could be to speed up the cleaning process onboard the ISS as well as offer an alternative to the use of disposable cleaning wipe which at present cause a significant recurring cost to the ISS.

Beginning January 2022, the primary development of this experiment has started with the development of a new experimental assembly which will enable the mixing of antimicrobial slimes with dirt ridden surfaces while maintaining the safety of astronauts aboard the ISS. Upcoming tasks within the development process are identifying appropriate slimes that can take the type of micro-organisms found aboard the station and the final assembly of the experiment for characterisation of its orbital durability.
