One of the key problems of long-term space missions is limited service life of units. The only exceptions are biological components of biological Life Support Systems - higher plants or microorganisms. These components are capable of self-restoration: after complete disintegration, they can appear again from seeds or spores. The estimate of failure intensity of BLSS regeneration component includes: a number of self-sustained sections of the regeneration component; permissible boost (how many times can productivity of a component be increased); time required to repair (restore) a component; the crew existence time, when all LSS regeneration components fail; failure rate of one section of a regeneration component. Evaluations show that for hydrogen-oxidizing bacteria and micro-algae very high reliability is achieved even for one or two sections. In the case of higher plants (due to low rate of self-restoration) bio-regenerative module has to be divided into 10 self-sustained sections operating simultaneously. These measures can decrease the probability of catastrophe by a factor of 106.
