Beginning of Rocket Science Rockets are machines that use escaping gas to move Tsiolkovsky (1900) Russian HS teacher – Inspired by Jules Verne (science fiction writer) – Explained how rockets work – Known as: Father of Rocket Theory
Conducted rocket experiments Arose attention of US military during WWII Known as Father of Modern Rocketry Robert Goddard (1915 -1941) American Physicist
First Rockets invented by Chinese over 800 years ago. –Used for fire works and weapons. Germans developed rocket bombs during WWII
At end of WWII US rocket research took off Cold War, US was frightened that Soviet Union would be superior to us in the arms race. NASA was formed July 29, 1958 (National Aeronautics and Space Administration)
Reaction Action Hot Gases Oxygen Fuel Fuel burned here
Oxygen is needed to burn fuel No Oxygen in space. Rocket must carry it’s own supply. In space rockets move without fuel Fuel only needed to change direction
Orbital velocity (8km/s) speed & direction a rocket must have to orbit the earth Suborbital (less than 8km/s) can fall back to earth Escape velocity (11km/s) speed & direction a rocket must travel to break a planet’s gravitational pull
