Carl Sagan Helped People Understand English


This is Shirley Griffith.

And this is Steve Ember with the VOA Special English program, Explorations. Today we tell about American scientist Carl Sagan. He spent much of his life helping make space travel possible far out in the universe. He also helped people understand science.

The year is nineteen-forty-seven. Twelve-year-old Carl Sagan is standing outside a small house in the eastern city of Brooklyn, New York. It is dark. He is looking up at the sky. After a few minutes, he finds the spot for which he has been searching. It is a light red color in the night sky. Carl is looking at the planet Mars.

Carl has just finished reading a book by American writer Edgar Rice Burroughs. It is the story of a man who travels from Earth to the planet Mars. He meets many strange and interesting creatures there. Some of them are very human. The name of the book is “The Princess of Mars.” It is just one of many books that Mister Burroughs wrote about travels to Mars.

In “The Princess of Mars,” the man who travels to Mars can make the trip by looking at the planet for several minutes. He then is transported there by a strange force.

Carl Sagan stands watching the red planet. He wishes he could travel across the dark, cold distance of space to the planet Mars. After a while, young Carl realizes this will not happen. He turns to enter his home. But in his mind he says, "Some day. . . Some day it will be possible to travel to Mars. "

Carl Sagan never had the chance to go to Mars. He died in December, nineteen-ninety-six. However,much of the work he did during his life helped make it possible for the American Pathfinder vehicle to land on Mars. It landed on July fourth, nineteen-ninety-seven. It soon began sending back to earth lots of information and thousands of pictures about the red planet.

Carl Sagan's friends and family say he would have been extremely happy about the new information from Mars. They say he would have told as many people as possible about what Pathfinder helped us learn.

Carl Sagan was a scientist. He was also a great teacher. He helped explain extremely difficult scientific ideas to millions of people in a way that made it easy to understand. He made difficult science sound like fun.

Carl Sagan was born in Brooklyn, New York in nineteen-thirty-four. Even as a child he wanted to be a scientist. He said it was a child's science book about stars that helped him decide to be a scientist.

Mister Sagan said he read a book that told how our sun is a star that is very close to earth. The book also said that the stars in the night sky were also suns but very far away. Mister Sagan said that suddenly, this simple idea made the universe become much larger than just Brooklyn, New York.

It should be no surprise to learn that Carl Sagan studied the stars and planets when he grew older. He did this at the University of Chicago. Later he taught astronomy at Harvard University and Cornell University.

In the nineteen-fifties, Mister Sagan helped design mechanical devices for use on some of the first space flights. He also published two important scientific theories that were later confirmed by space flights. One theory was that Venus is extremely hot. The other was that Mars did not have a season when plants grew as scientists had believed. He said that the dark areas on Mars that were thought to be plants were really giant dust storms in the Martian atmosphere.

Mister Sagan was deeply involved in American efforts to explore the planets in our solar system. He was a member of the team that worked on the voyage of Mariner Nine to Mars. It was launched in nineteen-seventy-one. Mariner Nine was the first space vehicle to orbit another planet.

Mister Sagan helped choose the landing area for Viking One and Viking Two, the first space vehicles to successfully land on Mars. He also worked on Pioneer Two, the first space vehicle to investigate the planet Jupiter. And he worked on Pioneer Eleven, which flew past Jupiter and Saturn.

Carl Sagan was a member of the scientific team that sent the Voyager One and Voyager Two space vehicles out of our solar system. He proposed the idea to put a message on the Voyager, on the chance that other beings will find the space vehicles in the distant future.

Mister Sagan worked for many months on what to say in the message. It was an extremely difficult task. When the Voyager space vehicles left our solar system they carried messages that included greetings from people in many languages. They carried the sound of huge whales in our oceans. And they carried the sound of ninety minutes of many different kinds of music from people around the world. Carl Sagan had created a greeting from the planet Earth.

Carl Sagan was an extremely successful scientist and university professor. He was also a successful writer. He wrote more than six-hundred scientific and popular papers during his life. And he wrote more than twelve books. In nineteen-seventy-eight, he won the Pulitzer Prize for one of them. It is called “The Dragons of Eden: Speculations on the Evolution of Human Intelligence.” He even helped write a work of science fiction in the nineteen-eighties. The book is called “Contact.” It is about the first meeting between beings from another world and the people of Earth. It was made into a popular movie.

Perhaps Carl Sagan may best be remembered for his many appearances on television. He used television very effectively in his efforts to make science popular. He first became famous in nineteen-eighty when he appeared on a thirteen-part television series about science. The show was called “Cosmos." It explored many scientific subjects--from the atom to the universe. It was seen by four-hundred-million people in sixty countries. Mister Sagan wrote a popular book based on his television show.

Millions of people saw Carl Sagan on television in the nineteen-seventies and nineteen-eighties. He especially liked to talk about science and scientific discoveries on the late night television program "The Tonight Show with Johnny Carson." Mister Sagan said he always tried to accept invitations to “The Tonight Show” because about ten-million people watched it, people who were not usually interested in science.

On television, Mister Sagan was a good story-teller. He was able to explain complex scientific ideas in simple ways. He believed that increasing public excitement about science is a good way to get more public supporters. He said much of the money for science and scientific studies comes from the public, and people should know how their money is being spent.

Some scientists criticized Carl Sagan because of his many appearances on television. They said he was not being serious enough about science. They said he was spending too much time appearing on television trying to make science popular. Other scientists valued his efforts to explain science. They said he communicated his message with joy and meaning.

One of Carl Sagan's last books is called “The Pale Blue Dot: A Vision of the Human in Space. Mister Sagan said he got the idea for the book from a picture taken by the Voyager One space vehicle. As it passed the planet Neptune, Voyager turned its cameras back toward the distant Earth.

Mister Sagan said. . . . “And there it was. Very small. The small blue dot in space with all of us. And you can't tell the difference between one nation and another. You can't even tell the difference between continents and oceans.

He said, "I thought it had a great deal to say about the foolishness of the issues that divide us. I thought it said we need to care for each other. And we have to also preserve this small dot in space. It is the only home we have ever known. "

Carl Sagan died December twentieth, nineteen-ninety-six in Seattle, Washington. He was being treated at a medical center there for a bone marrow disease. Carl Sagan was sixty-two years old.

This Special English program was written by Paul Thompson and Nancy Steinbach. It was produced by Paul Thompson. This is Shirley Griffith.
