Hi Hello, Vandin. Yes, I have. I'll do my best to answer. Thank you for joining us today, Miss Himmel. Although this is not my area of knowledge, I'll try to give some general info.
Water is used in many things.
Drinking is obvious, but they also use it for food and drinks. For example, some foods are dehydrated and then have to be rehydrated on orbit. As for the recycling system, yes, there is one on board. I think the Shuttle launches with a certain supply of water and then it is added to or maintained with the recycling system. At least from my collegues.
