Rockets, Satellites, and the International Space Station

Rockets • Rockets contain a tube, combustible material, and the payload. • The speed at which the exhaust leaves the rocket is called the exhaust velocity

Remote Sensing • Science of taking measurements of Earth from space • Used to show healthy versus unhealthy vegetation, water pollution, erosion, weather tracking

Life Support Systems on the ISS

Focusing Questions for Brain. Pop • What are natural and artificial satellites? • What are the 2 orbits for satellites? • How far are they above Earth? • How many countries are involved in building the ISS? • What factor is eliminated in space? • How far are GPS satellites above the Earth? • How many satellites are above you at one time?

Hubble Telescope • Computers can enhance telescope images using Charge Coupled Devices. • They convert light signals into digital format.

How Do Rockets Get To Other Planets?

Global Positioning Systems • Uses 24 satellites in orbit 20, 000 km above Earth’s surface • Satellites send out radio signals, GPS receivers measure distance from satellites by measuring lag time. • GPS Receivers use triangulation to pinpoint location

Satellites Geosynchronous Orbit • Located 36 000 km above Earth’s surface • Take 24 hrs to orbit • Used for radio and television satellites Low Earth Orbit • Located 200 -800 km above Earth’s surface • Take 1. 5 h to orbit • Used for telephone communication satellites
