How could you make space exploration more cheaper?

To make space exploration cheaper, we could invest in reusable rocket technology, which significantly reduces costs by allowing the same hardware to be used for multiple missions. Additionally, fostering partnerships with private companies can leverage innovative solutions and competition, driving down expenses. Utilizing 3D printing for manufacturing components on Earth and in space can also decrease material costs and waste. Lastly, promoting international collaboration can spread financial burdens and share resources, making missions more affordable.
