Part 2/7:
Upon embarking on this massive voyage, the crew faces the challenge of human continuity over such an extensive timespan. To ensure the mission can persist through generations, 30 infants are bred through in vitro fertilization (IVF), resulting in a new generation of voyagers who will one day fulfill the mission's objectives. However, they are raised in isolation to prevent feelings of homesickness, leading to significant concerns regarding their resilience when faced with the many challenges of space travel.
