2. Rocket Science NASA developed a rocket engine – This new type of engine was used chemical reactions to thrust an object straight up in the air – Before the rocket engine there was the jet engine Used to push something forward Used in planes Importance of Rocket Science – Space Race United States and Soviet Union racing to space During cold war this was important to prove who was smarter

3. Types of Rockets Types of Rockets llllll Artificial satellites – satellite is lifted from the earth's surface by a rocket – Once in space the satellite is propelled by a different rocket – 5 types of satellites Research- measure fundamental properties of outer space Communications- used for radio, phones, and TV Meteorological- used to collect data about weather. Navigational- used for navigation systems (originally made for submarines allowing them to know where they were going while underwater) Applications- designed to test ways of improving satellite technology itself – This allowed NASA to create better satellites than Soviets

4. Types of Rockets Cont. Types of Rockets Cont. lllll Space Craft – machine designed for spaceflight – often used for earth observation, meteorology, navigation, planetary exploration – usually carries people into space Allowed America to take the first man to the moon (Apollo 11) Scientific Space Probes – unmanned machines that are lifted into space by rockets – used to explore interstellar objects Such as moons, planets, sometimes asteroids and comets.

5. Military Uses Large Guided Missiles – unmanned space or air vehicle carrying an explosive warhead – path can be adjusted during flight – Powered by rocket engines – Four types Air to Air-fired by aircraft at enemy aircraft Surface to Air-fired on ground against enemy aircraft Air to Surface-fired by aircraft at ground position Surface to Surface-shot from ground at positions on the ground (includes ship and submarine launched versions) Click the first link to watch a guided missile launch click the 2 nd link to watch the damage of a us missile – http://www.youtube.com/watch?v=Z3RKn_7Pcw0 http://www.youtube.com/watch?v=Z3RKn_7Pcw0 – http://www.youtube.com/watch?v=rk0mmZX8jcY http://www.youtube.com/watch?v=rk0mmZX8jcY

6. Military Use Cont. Short Range Missiles – Bazooka Light weight metal tube from which rockets are launched Often referred to as a “stovepipe” First rocket used in warfare Mainly used as an antitank weapon and a weapon to destroy bunkers. – Short Range Guided Missiles Replaced bazooka as the antitank weapon Fired at short distance at about 50 meters off the ground to destroy tanks

7. NASA’s Future NASA planned on building a permanent moon base – President Obama cancelled this due to budget cuts NASA announced a plan to launch a man onto Mars by the year 2037.
