That’s what I was wondering, if someone could even DO the mission for under $20million.
Meanwhile Hollyweird keeps churning out remakes for $50-150million in production/advertising expenses.
Modern lighter materials, and more powerful boosters than the 1960s technology should help bring the costs down.
Also, it would help a lot if an early rocket stage could use atmospheric oxygen rather than hauling its own.
All that said, a $200 million dollar prize would make the endeavor have nearly guaranteed profitability.
