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

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radio, phones, and TV• Meteorological- used to collect data about weather.• Navigational- used for navigation systems (originally made for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

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.

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

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

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.
