And not just a little less money. Apollo was around 2.5% of the GDP for 10 years. That'd be about $200B a year today. For comparison, an SLS launch is about $2B
2.5% of the US GDP ($26 trillion in 2023) would be 600 billion. At its peak in 1967, the Apollo program budget was 3 billion, while the US GDP was about 850 billion. So 0.35 percent. US government spending in 1967 was about 112 billion, so closer to 2.5 percent of the federal budget, not the GDP. Converting to today’s 6,000 billion federal budget, about 150 billion today, or not quite 20% of the defense budget, the largest federal expenditure after Social Security (the defense budget is essentially tied with Medicare).
