I'm looking for some solid numbers that break down the mass of the ISS into functional categories (with the goal of making a neat pie chart). Such categories might include the mass of...
- Docked reentry craft
- Consumables (food)
- Scientific experiments
- Power generation and thermal systems
- Structural components (truss structure)
- Pressurized modules
- LSS equipment
Where might I find such data? Are there any pre-compiled lists? Additionally, because ISS mass changes with each arrival of a resupply craft, is there anywhere where the ISS's mass is tracked somewhat-live?
