$360,000/ hour to operate Space Station
$720,000/working hour (assuming work & exercise = 12 hours/day)
Astronauts spend 2 hours a day exercising to prevent bone loss
Probably only work and exercise 12 hours a day, so only 10 hours a day of work
Note: The only supplement NASA gives crews is vitamin D - Sept 2015 2,000 IU daily, which is not enough
I speculate that if astronauts got 8,000 IU of vitamin D daily that:
- Astronauts could spent 1 hour a day more actually working
Just #1 would save $720,000/day - Astronauts would be healthier – and thus less time off due to sickness
- Less DNA damage from high-energy environment
Vitamin D reduces damage from Cancer radiation treatment by 3X
I had been thinking about the value of a person's time
Then realized that an astronauts time is very costly

Web - in addition to Vitamin D, astronauts also need Magnesium
Suspect that the water recycling system on Space Station removes Magnesium
