Summary of health and safety issues: I replaced the batteries of suits n°3, 4 and 5, since they weren’t usable. Tests were conducted on voltage and airflow on maximum power of the suits for 4 hours, with measurements every 30 minutes. Here’s the results(very positive):

So suits 3,4 and 5 are fully functional now. I also would like to add that our airflow testing isn’t perfect, thus, even if it gives a general idea, it can’t be fully trusted. The voltage results show amazing results, and even after 4h of maximum power usage, the suits are still above 12V mark.

Questions, concerns and requests to Mission Support: It could be interesting to think about a solution to test the air flow of each suit and add it to the checklist between each EVA, and determine an approximate lifetime of a suit battery.
