1. Space Exploration
Rocket Science

2. Rocket Science
A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust from a rocket engine.
Rocket engine exhaust is formed entirely from propellants carried within the rocket before use

3. Fireworks
Fireworks were the beginning concept dating back to around the 7th century invented in China

4. Rockets for military and recreational uses date back to at least 13th century China.
At the beginning of the 20th Century, there was a burst of scientific investigation into interplanetary travel, largely driven by the inspiration of fiction by writers such as Jules Verne and H.G.Wells.
The War of the Worlds
The Time Machine
The Invisible Man
The Island of Doctor Moreau
Journey to the Center of the Earth
Twenty Thousand Leagues Under the Sea
Around the World in Eighty Days

5. The Beginning of Rocket Science
Around 1900 Russian scientist Konstantin Tsiolkovsky began studying rockets
He believed they were the future to space exploration
He never built any, just explained how they worked
“Father of Rocket Theory”

6. Konstantin Tsiolkovsky
Russia
High School Math

7. Robert Goddard an American physicist began building and testing rockets from 1915-1941
From he built and tested more than 150 rockets
By the beginning of WWII ( ) the military became very interested in rockets
“Father of Modern Rocketry”

8. German scientist Wernher von Braun
He designed the V-2 combat rocket that was used during WWII to bomb England
After WWII he defected to the U.S. and worked for the Army then NASA developing the Saturn V rocket

9. V-2 Rocket (Vergeltungswaffe 2, "Vengeance Weapon 2") technical name Aggregat-4 (A4)
over 3,000 V-2s were launched
Killed:
9,000 civilians and military personnel
12,000 forced laborers
London 1945

10. V-2 Engine cut-away
It used a 75% ethanol/water mixture for fuel and liquid oxygen (LOX) for oxidizer
The combustion burner reached a temperature of 2500–2700 °C (4500 – 4900 °F)
First human artifact to enter outer space

11. NASA was developed right after WWII during the cold war between the U
NASA was developed right after WWII during the cold war between the U.S. and the Soviet Union.
The cold war was an arms (weapons) race to see who could become the most superior military power
NASA was formed on
N – national
A – aeronautics
S – space
A – administration

13. How Rockets Work All rockets work on Newton’s Third Law of Motion
for every action there is an equal and opposite reaction

15. How Fast is Fast Enough
To escape Earth’s gravitational pull we must travel at a speed of 11 km/s (7 mi/s) or ≈ 25,000 mph

16. The earliest rockets used gun powder
Goddard began using liquid fuels
Liquid fuels will burn as long as oxygen is present
Since outer space has little to no oxygen we must bring liquid oxygen to allow the fuel to burn (they are very explosive)
Without the oxygen there would not be enough thrust to propel a rocket
