Can a 12-year-old boy go on a space mission with his crew on a spacecraft?

It is highly unlikely that a 12-year-old boy would be allowed to go on a space mission with a crew on a spacecraft. Space missions require extensive training, physical fitness, and mental preparedness, which are typically not achievable for someone so young. Additionally, there are strict age requirements and regulations in place for astronauts, and it is unlikely that a 12-year-old would meet these criteria.

No, a 12-year-old boy cannot go on a space mission with his crew on a spacecraft. Astronauts must undergo rigorous training and meet specific physical and mental requirements to participate in space missions. The minimum age for astronauts to be considered for selection is typically around 25 years old.
