Space Travel It is estimated that for humans to have first reached Australia approximately 65,000 years ago Links to an external site., they would have had to travel across vast bodies of open water. Much is unknown about how exactly they achieved this. Archaeologists and historians credit this as one of the first, remarkable achievements made by humans. While admirable today, their courage could also be described as reckless. When these early humans set sail, they took incalculable risks. They had to weather the scorching sunlight that threatened them with dehydration. They had to accept sharp pangs of hunger due to a lack of assured food sources. They had to take on the challenges of navigation with primitive rafts... all with zero assurance that anything would meet them at their journey's end (Treadwell, 2020). Space exploration is a hugely expensive affair. Should we spend money on space exploration when we have so many problems on planet Earth? Let's debate the pros and cons of space exploration and the reasons for whether or not we should be investing in space agencies and programs. Be sure to back up your argument with research.
