SCIENTISTS
LEONARDO DA VINCI Leonardo da Vinci (Born April 15, 1452 – Died May 2, 1519) Italian polymath – incredibly diverse talents and interests Painter, architect, mathematician, engineer, astronomer, inventor, geologist, historian, writer, and many other things Mostly well known for his paintings, but also made contributions to math and engineering Tactician and engineer during war Obsessed with phenomenon of flight – designs for parachute, flying machines, giant crossbow, winged machines
ARCHIMEDES
WHAT ARE ROCKETS? Launch vehicles that use propellant to create vertical thrust Uses: Space exploration Satellite launching Military weapons Types of Rocket Engines: Solid Fuel Liquid Fuel Ion thruster
HISTORY OF ROCKETS Hero of Alexandria used principle of thrust to create a spinning turbine (100 BC) First rockets powered by gunpowder in China (1200s) Johann Schmidlap builds multi-stage rocket(1591) Used for show or warfare, highly inaccurate Goddard and liquid fuel rocket

OTHER TYPES OF ROCKET ENGINES Ion thrusters Very low thrust but extremely high specific impulse Dawn spacecraft used 275 kg of propellant to accelerate to 10km/s Could be used for interstellar missions Very efficient Deep Space 1’s ion thruster
