Another day off.. That is pretty exciting and not only did you get the day off... but I did too! A great day for a quick trip to the moon... I hear its full of cheese .. What do you think?THIS WEEK: So all of you are telling me you know the parts of a fraction and how to make fractions... and we have been working on adding and subtracting fractions with common denominators... we will continue with fractions this week and move into multiplying and dividing fractions.
CALCULATOR !!! Trust me your going to want a fraction calculator!!
SPACE FACT: THE PARTS OF A ROCKET
The structural system, or frame, is similar to the fuselage (body) of an airplane. The frame is made from very strong but light weight materials, like titanium (stronger than steel) or aluminum, and usually employs long "stringers" which run from the top to the bottom which are connected to "hoops" which run around the circumference (distance around). The "skin" is then attached to the stringers and hoops to form the basic shape of the rocket. The skin may be coated with a thermal protection system to keep out the heat of air friction during flight and to keep in the cold temperatures needed for certain fuels and oxidizers. Fins are attached to some rockets at the bottom of the frame to provide stability during the flight.
The payload (what they carry) system of a rocket depends on the rocket's mission. The earliest payloads on rockets were fireworks for celebrating holidays. The payload of the German V2, shown in the figure above, was several thousand pounds of explosives. Following World War II, many countries developed guided missiles armed with nuclear warheads for payloads. The same rockets were modified to launch satellites with a wide range of missions; communications, weather monitoring, spying, planetary exploration, and observatories, like the Hubble Space Telescope. Special rockets were developed to launch people into earth orbit and onto the surface of the Moon.
The guidance system of a rocket may include very sophisticated sensors, onboard computers, radars, and communication equipment to maneuver the rocket in flight. Many different methods have been developed to control rockets in flight. The V2 guidance system included small vanes in the exhaust of the nozzle to deflect the thrust from the engine. Modern rockets typically rotate the nozzle to maneuver the rocket. The guidance system must also provide some level of stability so that the rocket does not tumble in flight.
As you can see on the figure, most of a full scale rocket is propulsion system. There are two main classes of propulsion systems, liquid rocket engines and solid rocket engines. The (rocket 1) V2 used a liquid rocket engine consisting of fuel and oxidizer (propellant) tanks, pumps, a combustion chamber with nozzle, and the associated plumbing. The (rocket 2) Space Shuttle, (rocket 3) Delta II, and (rocket 4) Titan III all use solid rocket strap-ons.
The various rocket parts described above have been grouped by function into structure, payload, guidance, and propulsion systems. There are other possible groupings. For the purpose of weight determination and flight performance, engineers often group the payload, structure, propulsion structure (nozzle, pumps, tanks, etc.), and guidance into a single empty weight parameter. The remaining propellant weight then becomes the only factor that changes with time when determining rocket performance.

2) Rocket Speed2
How fast does a rocket need to go in order to achieve orbit ( orbit means till it can travel around the earth..) _____________________?
3) If you were in a rocket, you would be 1 out of what part of a rocket (see the diagram above)______?
4) Would you want to walk on the moon or orbit the moon___________? What fraction of your class do you think would want to orbit or walk on the moon_________?
Do you feel it? Come on you must... close your eyes and think DOG... BULLDOGS!! The first game... is on the 28th ... how EXCITING!
