t takes about $30,000 to send a single water bottle to space.
With astronauts living on the International Space Station, it is incredibly costly to continue to provide them the resources that they need in order to both work and survive day-to-day in space. Due to the awfully high expenses of resupply missions, scientists and engineers have been designing systems that will allow astronauts to live as close to 100% sustainably as they can.
So, astronauts on the ISS drink and use water recycled from urine, sweat, and condensation. This allows up to 98% of the water on the station to be reused.
