The system mass has been estimated to be 13.4 tonnes. The savings on the LSS mass must be
evaluated carefully due to the large uncertainty on the state of the development of certain
subsystems. However, the impact on the consumables is significant as shown in Table 3-16.

Due to the anticipated high-recycling efficiencies the amount of needed consumables is reduced
to 10.3 tonnes. In addition, the amount of produced waste is reduced to 6.7 tonnes making
alternative options to jettison more likely.
The life support system has been estimated to have an approximate mass of 13.4 tonnes. The
detailed mass budget is shown in Table 3-17.
