**6. Conclusion**

Numerical methods developed in ethology of humans in space have contributed to give insight into adaptive behaviors that underlie human intelligence as multiple processes of optimization of the individual-environment relationship. Human being's activity is the heart of the system, be it natural or artificial. AI can perform additional functions by processes of imitation, cooperation, and automation that include the diversity of the crewmembers, cyclicity of their behavior, and autonomy of the confined and isolated crew from Earth.

From the individual to the cultural crews' behavior that expresses individual intelligence to collective human intelligence, space missions will improve as intelligent missions by associating AI as follows:

Artificial intelligence + ∑Human intelligences ∗ = Intelligent missions (∗ Individual intelligence + Emotional intelligence + Collective intelligence)
