Space exploration is crucial to many people today. Space exploration is worth the cost. One reason why space exploration at extreme conditions is important to humans is because it can generate wealth and it expands our knowledge‚ in other words it helps us seek the unknown. Space exploration is worth the cost because it generates almost as much as twice as much of the money that it actually takes to send the astronauts into space. Expands our knowledge and helps us‚ humans‚ seek the unknown. Scientist
