Life support parameters represent the payload of a rocket and are measured in kilograms of supplies per day. They are subdivided into human needs, and human waste. Calculating the number of minimal kilograms of supplies required for each day per person is critical to the Lunar Settlement and would establish limitations to the number of people inside. Until the ISRU technology is available the lunar settlement would depend of the earth importations.

These number were calculated for the MIR and utilized in the ISS. The most difficult issue of a lunar settlement is the cost of the payload, which is nearly US$ 10,000 for every kilogram sent to space.

The table below shows that every person needs a load of *** per day. Multiplying this number by 30 days, there would be 707.2 kilograms of supplies per person per month.
