Space Transportation NASA is responsible for regulating and directing the entire US space program Space vehicles take us beyond the earth Currently consists primarily of unmanned exploration vehicles

Apollo Space Program First Flight – Unmanned – February 26, 1966 Final Flight – Apollo 17 – December 7, 1972

Apollo 11 July 16, 1969 – July 24, 1969 First Lunar Landing – July 20, 1969

Apollo 11 Command Module in Lunar orbit The Eagle

Apollo 11 Lunar Module leaving the Moon Apollo 11 returns to Earth

Space Shuttle Space Shuttle program: The Shuttle was the first reusable spacecraft

Space Shuttle Accidents Challenger January 28, 1986 Columbia February 1, 2003

Exploratory Vehicles Currently, exploratory missions are being done without human crews They carry cameras & other exploratory equipment

Using 2 or more forms of transportation to move people or cargo more efficiently Examples: Bus or car to airport - plane to a coastal city – bus or taxi to dock - then board a cruise ship Cargo is loaded into containers and placed on a ship - then loaded onto a train - then transferred for travel by truck Advantage: Saves time and money because it is very efficient Intermodal Transportation

TransmissionTransfers power from the engine to the axles and wheels: Structure and support: Propulsion: Guidance: Suspension: Control: GPS Frame Engine Steering Springs & shock absorbers Brakes & Steering Navigation: Automobile Subsystems When all subsystems work together the car functions properly

Universal System Model of Technology

Universal: Model: System: Technology: Pertains to all or everything Group of parts working together in an organized way to complete a task A representation of something Something that extends human abilities or satisfies a need or want

Universal Systems Model of Technology A model that can be used to describe every type of technology from the very simple (pencil) to the very complex (computer)

Universal System Model of Technology Input Goal:What you want the system to do 7 Resources Materials:What things are made of Information:Knowledge used to create technology Energy:Source of power used to create technology Capital: Accumulated wealth (Money, Credit or Land) Time:How long it takes to complete a task Tools &Instrument that increases ability to do work Tool with a power systemMachines: People use SKILL (Combination of knowledge & practice that enables you to do something well) to create technology People: Everything necessary to design or develop a product or system

The most important resource (or input) for any technology is People Why???????? Without PEOPLE there would be no technology

Universal System Model of Technology InputProcessOutput Goal: What you want the system to do Resources: (7) People, tools & machines, information, time, capital, energy, materials The steps that lead to a result The result that comes out of the system Feedback: Comparing the result to the original goal; adjustments are made to the inputs and/or processes

Have inputs, process, outputs & feedback Universal Systems Model of a City Bus System Inputs: Process: Output: Feedback: Goal (Safe arrival at scheduled stops), Buses, people to operate buses, fuel to provide energy, schedules, passengers Loading passengers, driving the bus Safe arrival at scheduled stops Comments from customers (passengers) Transportation Systems

We can use the Universal Systems Model to describe any of these Transportation Systems as well Transportation System Getting to school on the School Bus / Car Ferryboat trip to Martha’s Vineyard Trip to Florida by Airplane / Train / Car Bus trip to a Case Jr. High away game
