For example, David Livingston argues that although space exploration costs an exorbitant amount of money, much of it goes right back into the paychecks of those involved, funding “manufacturing, research and development, salaries, benefits, insurance companies, doctors, teachers, scientists, students blue- and white-collar workers, and corporations and businesses both large and small” (Source A). Space exploration functions as an umbrella term that encompasses hundreds of smaller faculties, each of which strengthening from overarching investment and improving the international economy. However, some, like Professor Russell Roberts, continue to argue that it should be a private business venture.

Margaret R. McLean expands upon this disturbing phenomenon, writing that we should learn from our mistakes on Earth to understand “the potential impact of our forays into the outer reaches of the solar system” (Source E).
