How much does it cost to go to space?

As a keen observer of the intersection of finance and emerging technologies, I'm often curious about the financial implications of groundbreaking advancements. One such question that intrigues me greatly is: How much does it actually cost to embark on a journey into the vast expanse of space? Is it a multi-million dollar investment, or has technology advanced to a point where space travel has become more affordable for civilians? This query strikes at the heart of the economic feasibility of space exploration and colonization, and I'm eager to understand the financial implications of such an endeavor.
