First thoughts:
1. What are “satellites”? Mention some satellites
that you know about.
2. What are man-made satellites used for?
II. Study the following words. Be sure you know them:
accurate, navigate, signal, speed, photo, shuttle man-made,
military, servey
III. Read the text and name the types of satellites used
to do different jobs.
The earth is one of several satellites of the sun. Satellites
are things that go around the sun or a planet at the same speed
all the time. The earth's biggest satellite is the moon, but since
1957, when Russia launched the first man-made satellite, there
have been hundreds of others sent up to do different jobs.
There are different kinds of man-made satellites in space.
Military satellites have cameras which can see what is
happening in other countries. These help countries defend
themselves against surprise attacks. Communication
machines, called Comsats, travel through space at the same
speed that the earth turns so that they are always over the same
place. Signals from one earth station are received and sent
back down to another station thousands of miles from the
first. Before Comsats, it was necessary to lay long expensive
cables, which couldn't carry many messages. Comsats carry
thousands of messages each minute.
Map makers are drawing much more accurate charts and
maps because they have photos from survey satellites showing
exactly where everything is, and weather forecasters have
photos of all the clouds around the world. They can see when a
storm is forming, and they can tell how long it will take to
strike. Navigators on ships and airplanes can now find out
exactly where they are by use of the Satnav system - even
when it is cloudy or foggy and no stars are to be seen.
