Focus
Remember the following prompts for analysis, and center all of the effort around deriving insights into these prompts: Questions:
- What is the percent difference between historical consumable usage rate assumptions and actual calculated usage rates in mission time frames between resupply?
Answer: Overall historical usage on the space station for the time period covered by client data was 1.04% less than assumed usage rates.
- What resupply quantities are necessary, considering planned resupply vehicle traffic from the ISS Flight Plan, planned On-Orbit Crew counts, and historical usage rates to sustain minimum supply thresholds, plus a 10% safety factor, through the next two years?
Answer: Usage quantities can be found in the table below.

- What resupply quantities meet the requirements of question #2 while minimizing launch vehicle quantity? (e.g., launching 10,000 granola bars would ensure the minimum thresholds are not violated, but is not a realistic or optimal strategy for balancing launch mass requirements with supply requirements)
Answer: Resupply quantities listed in the table above meet the minimum launch vehicle quantity based on the schedule represented in the iss_flight_plan data.
- What month in the next two years of the Flight Plan timeline is most likely to incur a violation of minimum supply thresholds?
Answer: The time period most likely to incur a violation of minimum resupply thresholds is the period between launches in February, 2025 and May 2025.
- Which consumables item(s) are most likely to incur a violation of minimum supply thresholds in the next two years of the future Flight Plan timeline?
Answer: Water is the most likely consumable to incur a violation of minimum resupply thresholds.
