Geography is the study of Earth and its climates. Scientists use it to study global warming and track the weather. Governments use it to learn where people live and work and to plan what to do with the land. It is now easier than ever to use geography because of a science called space technology.

The United States launched its first satellite in 1958. Some space missions that followed were geographical studies. In fact, earth science is a big part of the work of the National Aeronautics and Space Administration (NASA).

Astronauts looked out of the space shuttle. They decided to take photographs of Earth from their vantage point. Over the years, picture quality improved. Shuttle photography now shows land features, such as rivers. It can even show the streets of large cities. Photos of the same places at different times show how the land is changing.

NASA does not use just photographs, though. In 1958 it launched TIROS (the Television Infrared Observation Satellite). This first use of a satellite to study Earth was effective in giving weather forecasts. It led to the creation of new space tools to use in geography.

The Landsat Program began in 1972. This satellite sent detailed views of Earth from space. The pictures were so precise that scientists could count the number and kinds of crops in a field. Landsat showed where Earth’s surface had faults along which earthquakes might happen. This information helped in the planning of new cities and factories. Landsat also made discoveries. In Antarctica it located ranges of unknown mountains. It pinpointed small lakes in Virginia that were no ton maps. Landsat, now more advanced, still flies today.

Another space tool is Earth Observing-1 (EO-1). This spacecraft flies right behind Landsat. It takes pictures of the same sites. The two sets of pictures, viewed together, show how cities grow and how other places, such as rain forests, become smaller over time. This helps scientists learn how people affect geography.

One of the newest space tools is the Geographical Information Systems (GIS). GIS is computer software that helps scientists to study Earth. GIS is different from earlier space tools. Businesses, schools, and even average people — not just the government —can use it to show them how changes in the planet might affect them.

A. the two groups of pictures can show the changes of Earth

B. EO-1 is practicing for future photography missions

C. Landsat is out of date and new pictures are needed

D. recent U.S. satellites are as advanced as the old ones

 

A Great Creator

Steven Jobs, the designer of Apple Computer, was not clever when he was in school. At that time, he was not a good student and he always made troubles with his schoolmates. When he went into college, he didn’t change a lot. Then he dropped out. But he was full of new ideas.

After he left college, Steven Jobs worked as a video game designer. He worked there for only several months and then he went to India. He hoped that the trip would give him some new ideas and give him a change in life.

Steven Jobs lived on a farm in California for a year after he returned from India.

In 1975, he began to make a new type of computer. He designed the Apple Computer with his friend in his garage. He chose the name “Apple” just because it could help him to remember a happy summer he once spent an apple tree garden.
