Study Notes
The Concept of Space Elevator: A Revolutionary Way to Reach Space
- The only current ways to reach space are becoming an astronaut or a billionaire.
- Being in orbit means falling towards something but moving fast enough to miss.
- Rockets need to go up and sideways fast to enter Earth's orbit.
- A space elevator taps into energy from Earth's rotation to get the cargo going fast.
- A space elevator would reduce the cost of launching cargo into space by 100 times.
- The cost to put one kilogram of payload into space is $20,000.
- After construction, a space elevator is projected to cost $200 per kilogram to launch cargo into space.
- A space elevator has four major components: the tether, anchor, counterweight, and climber.
- The biggest challenge in building a space elevator is creating a tether that is light, strong, and can withstand atmospheric corrosion, radiation, and debris impacts.
- The climber requires a lot of energy to go up and needs a power source.
- There are still some major technological hurdles to overcome in building a space elevator, and it is not without risk.
- Some experts have proposed building a space elevator on the Moon before building one on Earth.
