Module 5 Space Environment1 Traveling in Space Ted Spitzmiller Author Pilot Dreamer

Module 5 Space Environment2 The Universe Everything we are aware of is a part of the known universe –Stars –Galaxies –Planets –Plants –Animals –Humans All made from the same elements

Module 5 Space Environment3 Galaxies Enormous collections of stars Our Galaxy is called the Milky Way Scientists estimate that our Milky Way has 100 Billion stars… many with planets

Module 5 Space Environment4 The Sun is a Star Center of our solar system A Hot body of Helium and Hydrogen gas Temperatures reach 15,000,000° Some stars have planets orbiting them

Module 5 Space Environment5 The Solar System Outer – Jupiter Saturn Uranus Neptune Pluto Inner – Mars Earth Venus Mercury

Module 5 Space Environment6 Relative Size of Planets Closest to the Sun Furthest from Sun Largest planet Rotates counter-clockwise Atmosphere is 78% Nitrogen, 21% Oxygen The “Red” Planet Pluto Neptune Uranus Saturn Jupiter Mars Earth Venus Mercury Sun

Module 5 Space Environment7 Space – the Final Frontier? The region of the universe beyond earth Great distances between significant bodies –Moon 240,000 miles –Planets 20,000,000 (Venus) –Sun 93,000,000 miles –Galaxies Light years A light year is 6 trillion miles

Module 5 Space Environment8 Characteristics of Space Defined as starting 62 miles above the earth Very few molecules (low pressure - almost a vacuum) No oxygen Very cold Little gravity (microgravity) Thickness of the atmosphere

Module 5 Space Environment9 Our Moon ¼ the size of the Earth Orbits the earth in 28 days Rotates on its axis once each 28 days –Lunar day is 28 earth days Far side never viewable from Earth

Module 5 Space Environment10 Meteors Meteoroids –rocks 10 meters or less –drift through space Meteor –If it enters the Earth’s atmosphere Meteorite –If it strikes the earth before burning up

Module 5 Space Environment11 Asteroids Often called minor planets or planetoids Larger than 10 meters Primarily inner Solar System Smaller than planets

Module 5 Space Environment12 Comets Composed of frozen gases, dust and ice Have no light source but reflect sunlight Tail –shaped by Solar wind –always points away from the sun

Module 5 Space Environment13 The Universe A Wonder of God’s creation But how can we explore it? There is no air out there

Rockets Module 414 Rockets Saturn V

Rockets Module 415 Chinese Invent Gunpowder First ‘solid fuel’ 1200 AD

Rockets Module 416Rockets Module 416 Gun Powder Mixture of: 15% charcoal, fuel to burn—carbon (C) 75% saltpeter (KNO 3 potassium nitrate) oxygen 10% Sulfur (S), also a fuel –lowers ignition temperature to increase speed of burning Charcoal color is why it is often called “black Powder”

Rockets Module 417 Solid Fuel Rockets William Hale ( ) devised spin stabilized rockets ‘Spin it’ or ‘fin it’ Solid fuel stored Combustion Chamber Exhaust nozzle

How does a rocket work? Module 5 Space Environment18

Rockets Module 419 Newton’s Three Laws of Motion Sir Isaac Newton First Law - A body at rest tends to stay at rest; a body in motion tends to stay in motion Second Law – Force equals mass times acceleration Third Law - For every action there is an equal and opposite reaction Reaction Action
