Study Notes
Human Powered Flight
- The first powered flight of a heavier-than-air machine was achieved by Orville Wright in 1903.
19th Century Spaceflight
- The concept of spacecraft propulsion was not yet developed in the 19th century.
Rocket Dynamics and Propulsion
- Building on Isaac Newton's laws of motion, William Moore explained rocket dynamics and propulsion in 1813.
Early Balloon Flight
- The first untethered balloon flight carrying humans occurred in the 18th century.
Somnium and Science Fiction
- Johannes Kepler wrote "Somnium," which is considered to be the first science fiction book.
Arthur C. Clarke Contributions
- Arthur C. Clarke is known for identifying the value of geostationary orbit (GEO).
Orson Welles and The War of the Worlds
- Orson Welles is known for his radio play adaptation of "War of the Worlds."
Rocket Mass Ratio and Mass Fraction
- The mass fraction is calculated as the reciprocal of the mass ratio.
- For a rocket with a mass ratio of 49.1, the mass fraction would be 0.02.
First Rocket to Photograph Earth
- In the 1940s, a rocket traveled beyond the Karman line and captured images of Earth.
Karman Line
- The boundary of space is defined as the transition point between aerodynamics and astronautics.
- Theodore van Karman was influential in determining this boundary.
