LESSON 4 · Humanity's Journey to Space
The New Space Age
Private spaceflight has reshaped the economics and pace of space exploration:
- Reusable Falcon 9 cut launch costs from $50,000 to under $3,000 per kilogram
- Crew Dragon ended US reliance on Russian Soyuz for ISS crew transport
- Inspiration4 flew the first all-civilian orbital mission in 2021
- Starship aims to carry 100-150 tons to orbit and slash costs further
- Blue Origin, Rocket Lab, and others are building a competitive launch industry
This shift from government-only to commercial spaceflight is the biggest change in the industry since the Space Race.
