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

Exploratory VehiclesCurrently, 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 shipCargo 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

Universal Systems Modelof 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 TechnologyUniversal System Model of TechnologyInput

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 isThe most important resource

(or input) for any technology is

PeopleWhy????????Without PEOPLEthere would be no technology

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
