Umm yes yes and if you do that the ISS mimic team would be very interested in seeing it (and more so if it could be integrated into our program :) )

I've been spending about ~10 hours a day on a startup idea I had recently, but if that falls through, I'll be in touch

ISS Mimic team member here - I love it. Great work!

And for anyone worried about astronaut privacy, the urine tank quantity does not reflect ... direct addition of urine from a crew member ;)

"Great" may be overstating things just a tiny bit especially in comparison to ISS Mimic but I'll absolutely take the compliment, thank you.

I'm also curious as to what the quantity actually does reflect – I clearly haven't peered deep enough into the soul of the UWMS.

Oh it definitely does reflect how much astronaut urine is in the tank, but the value changes (sadly?) don't indicate direct use of the toilet due to how the system is configured.

Well where exactly are my tax dollars going then? /s

Now I'm genuinely curious — what _does_ it reflect then?

It might include additional liquid for flushing/cleaning etc?

What I'm curious about is when the levels go down. Does that mean it's emptied over some country?

I thought, that most/all water is recycled into the drinking water tank after some processing.

Aliens using the ISS toilet confirmed.

ISS mimic team member here - if you're still in the Houston area I'd love to buy you a drink sometime

Thanks for making ISSlive

The mass data is calculated from all the launched mass but I have no idea why it's a telemetry value unless the ISS echoes it back for some reason

That's very common in ISS operation schedules - next spacewalk is on GMT xx next launch on GMT xx, etc

I expect it's easier and more useful to track days until event or days since event
