Wan-Hu
Made a rocket powered chair. While testing he and the chair were blown to pieces by the rockets. -
Where the name rocket came from.
The name rocket came from Italy because rocchetto is rocket in Ialian and means projectile. -
Sir William Congreve
Designed rockets for the British military. -
Konstantin E. Tsiolkovsky
1857-1935 suggested the use of liquid propellants for rockets. Using liquid propellants could give the rockets more range. Became known as the father of moder astronautics. -
Idea of Space Exploration
Konstantin Tsiolkovsky proposed the idea of space exploration by rocket. -
Robert H. Goddard
Tried to get rockets to achieve higher altitudes than lighter-than-air balloons. -
Wernher Von Braun
1912-1977 Helped build and design the V-2 rocket. Later in America helped with the U.S. Space race with the Soviets. -
V-2 Rocket
Formidable weapon that when fired could devastate several city blocks. -
Hermann Oberth
1894-1989 His writings were important. Because of them, many small rocket societies sprang up around the world. In Germany, the Verein fur Raumschiffahrt is one and led to the development of the V-2 rocket, which was used against London during World War II. -

Future rocket fuel
Plamsa engines are being experimented on for future rocket fuel. -
Current Rocket Fuels
Liquid propellant, cryogenic propellant, hypergolic propellant, mono-propellants, solid propellants, hybrid propellants. -
Key aerodynamic ideas applying to rockets
Lift-parallel to the direction of motion
Drag- opposite to the direction of motion
Weight- parallel to the direction of motion
Thrust- opposite to the direction of motion -
Laws that explain how rockets work
An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
The relationship between an object's mass m, its acceleration a, and the applied force F is F=ma acceleration and force are vectors.
For every action there is an equal and opposite reaction.
