Computers are one of the most important inventions ever. If computers had
             not been invented, technology would not be developed to its current state.
             Since the computers invention, society has changed drastically. Computer
             technology is so helpful, that it is even used to create newer, better
             computer equipment. Almost everything today is linked in some way, to
             Before computers were invented, very little was known about outer space.
             With the technology we have now, we are learning new things everyday.
             Computers are used to follow the paths of asteroids and predict their future
             movements. On 6 December 1997, a mile-wide asteroid was discovered by
             astronomer Jim Scotti, a member in the University of Arizona's Spacewatch
             group. He used a 77-year-old telescope along with an electric camera that
             caught the asteroid on film. He then used a computer specially programmed
             to look for objects moving against the background of fixed stars. The
             computer worked so well that Scotti described the asteroid as "sticking out
             like a sore thumb" (Jaroff 68). His information was relayed to Brian
             astronomer, to determine the course of the asteroid. After many
             calculations, Marsden's computer showed the rock would pass Earth
             approximately 600,000 miles away. This may not seem important, but if an
             asteroid was on a line with Earth, the computer would show us and enable us
             to deflect the projectile with nuclear power (Jaroff 69). Thus, computers
             In "Spies in the Sky", Bill Sweetman writes about the use of satellites and
             computers for spying on other countries. On 20 December 1996, three
             computer operated satellites were released into orbit for use against Iraq.
             Each one costs 800,000,000 dollars or more, most of which is spent on the
             computer equipment needed to control them. When the radar data is received
             from the satellite dish, it has low resolution and lacks clarity....
