Space satellite does not need to be streamlined in order to fly since there is no air in space to
slow it down. However, it does need source of energy to power its electronic circuitry, so
satellite has large solar panels that convert sunlight into electricity. In addition, it is
necessary for satellite to stay in exactly right position so that its antennae face radio stations
on ground. For this reason it is equipped with gas thrusters which can move satellite into
correct orbit, high above Earth.
