((SFX: Apollo eleven countdown tape)) A rocket launch (1) countdown, a common sound in the nineteen-sixties, but this was not just another launch. It was the beginning of an historic event. It was the countdown for Apollo eleven -- the space flight that would carry men to the first landing on the moon.
The ground shook at cape Kennedy, Florida the morning of July sixteenth, nineteen-sixty nine. The huge Saturn five rocket moved slowly up into the sky. It rose perfectly. Someone on the launch crew spoke the words, "good luck. And (2) Godspeed."
Today, Stan Busby and jack Wetzel tell the story of the (3) flight of Apollo eleven
. Voice one:
In the (4) spacecraft at the top of the speeding (5) rocket were three American astronauts whose names soon would be known around the world. Neil Armstrong, Edwin Adrian and Michael Collins.
Neil Armstrong was the commander of the spacecraft. He was a test (6) pilot. He had flown earlier on one of the two-man (7) Gemini space flights. Armstrong was a calm person, a man who talked very little.
Edwin "buzz" Adrian was pilot of the moon Lander (8) vehicle. The astronauts gave it the name "eagle." Adrian had flown on the last of the Gemini flights. He also was a quiet man, except when he talked about space.
Michael collins was the pilot of the command (9) module vehicle, "Columbia." he also had made a Gemini flight. He would wait in (10) orbit around the moon while Armstrong and Adrian landed and explored the surface. Collins was very popular and always ready with a smile. Voice two:
Two-and-one-half minutes after the Apollo eleven (11) launch, the first-stage rocket separated from the spacecraft. Twelve minutes later, the spacecraft reached orbit. Its speed was twenty- nine- thousand kilometers an hour. Its orbit was one- hundred- sixty- five kilometers above the earth.
This was the time for the crew to test all the spacecraft systems. Everything worked perfectly. So, the NASA flight director told them they were "goes" for the moon. They fired the third-stage rocket. It increased the speed of the spacecraft to forty- thousand kilometers an hour. This was fast enough to (12) escape the pull of the earth's (13) gravity
. Apollo eleven was on its way to the moon. In seventy-seven hours, if all went well, Apollo eleven would be there.
Voice one:
Halfway to the moon, the (14) astronauts broadcast a color television program to earth. The broadcast showed how the astronauts lived in the spacecraft. It showed their instruments, food storage, and details of how they moved and worked without gravity to give them weight. The television broadcast also showed the earth behind apollo eleven. And it showed the moon growing larger in the blackness ahead. As hours passed, the pull of the moon's gravity grew stronger. Near the moon, the astronauts fired rockets to slow the spacecraft enough to put it into moon orbit.
Voice two:
Apollo eleven (15) circled the moon while the crew prepared for the landing. Finally, spacecraft commander Armstrong and NASA flight controllers agreed it was time to separate the Lander module "eagle" from the command module "Columbia."
Armstrong and Adrian moved through the small opening between the two spacecraft. Then they moved eagle away from Columbia. Armstrong reported, "The eagle has wings!" the (16) lunar module was ready. Men were about to land on the moon.
On earth, all activity seemed to stop. President Richard Nixon gave federal government workers the day off to watch the moon landing on television.
Around the world, five- hundred- million persons watched the television report. Countless millions more listened on their radios. Voice one:
Armstrong and Adrian fired the Lander rocket engine. The firing slowed the spacecraft and sent it down toward the landing place. It was in an area known as the "sea of tranquility."
The lunar Lander, controlled by a computer, dropped toward the airless surface of the moon. One- hundred- forty (17) meters from the surface, the astronauts took control of the Lander from the computer. They moved eagle forward, away from a very rocky area that might have caused a difficult landing.
The voices of Adrian and Armstrong could be heard in short messages. "Forward... forward...good, forty feet, kicking up some dust, big shadow, drifting to the right a little, contact light, okay, engine stop."
Armstrong reported, "(18) tranquility base here. The eagle has landed!"
voice two:
NASA's plan had called for the astronauts to test (19) instruments, eat and then rest for four hours before leaving the eagle. But Armstrong and Adrian asked to cancel the four-hour sleep period. They wanted to go out onto the moon as soon as they could get ready.
NASA controllers agreed.
It took the astronauts more than three hours to complete the preparations for leaving the Lander. It was difficult -- in eagle's small space -- to get into space suits that would protect them on the moon's surface
. Voice one:
Finally, Armstrong and Adrian were ready. They opened the door. Armstrong went out first and moved slowly down the ladder. At two hours fifty-six Greenwich mean time on July twenty-first, nineteen- sixty- nine, Neil Armstrong put his foot on the moon.
"That is one small step for a man," he said, "one giant leap for mankind."
The world could see the history-making event on television. But the man who was closest to what was happening, Michael Collins, could only listen. He was orbiting the moon in the command module Columbia. It did not have a television receiver.
Voice two:
Armstrong moved carefully away from the eagle. He left the cold black shadow of the Lander and stepped into the blinding white light of the sun.
On earth, all was quiet. No sound came from televisions or radios. No one felt able to talk about what was happening.
Armstrong began to describe what he saw. "The surface appears to be very, very fine grain, like a powder. I can kick it loosely with my toes. I can see footprints of my boots in the small, fine (20) particles. No trouble to walk around."
voice one:
Adrian appeared on the ladder. Down he came, very slowly.
Soon, both men were busy placing experiments to be left behind on the moon. They collected more than thirty kilograms of rock and soil to take back to earth. They moved easily and quickly, because the moon's gravity is six times less than earth's.
Hours passed. Too soon, it was time to return to the eagle. Armstrong and Adrian re-entered the Lander. They rested for a while. Then they began to prepare to launch the Lander for the return flight to the orbiting command module.
Voice two:
listeners on earth heard the countdown from tranquility base. "Three, two, one...first stage engine on ascent. Proceed. Beautiful. Twenty-six...thirty- six feet per second up, very smooth, very quiet ride." eagle was flying. Man had been on the moon for twenty-one and one-half hours.
Eagle moved into the orbit of the command module. It connected with Columbia. Armstrong and Adrian rejoined Collins in the command ship. They separated from eagle and said goodbye to it. The Lander had done its job well.
Voice one:
Eight days after it started its voyage to the moon, Apollo eleven splashed down in the Pacific Ocean. Left behind on the moon were the footprints of Armstrong and Adrian, an American flag and scientific equipment. Also left forever on the moon is a sign with these words: "Here men from the planet earth first set foot on the moon -- July, nineteen-sixty-nine ad. We came in peace for all mankind."

TITLE=EXPLORATIONS #1948 - PROJECT APOLLO (PART TWO): APOLLO THIRTEEN BYLINE=MARILYN RICE CHRISTIANO
ANNCR:
Explorations --- a program in special English by the Voice of America. (Theme)
ANNCR:
American （1） astronauts in Apollo eleven landed on the moon July twentieth, nineteen- sixty- nine. A second landing was made four months later. Both （2） flights were almost perfect. Everything worked as planned. Everyone expected the third moon-landing flight, Apollo thirteen, would go as well as the first two. But it did not.
Today, Shirley Griffith and Sarah long tell you the story of Apollo thirteen --- the flight that almost did not come home.
(Theme)
Voice one:
Apollo thirteen (3) roared into space on Thursday, April eleventh, nineteen- seventy. The time was thirteen-thirteen, one-thirteen p.m. local time.
Navy captain James Lovell was （4） commander of Apollo thirteen. He had flown on Apollo eight, the first flight to （5）orbit the moon.
The two other crewmembers were （6）civilians -- John Swigert and Fred Haise. Apollo thirteen was their first space flight.
Voice two:
The apollo thirteen spacecraft was like the earlier Apollo's. It had three major parts. One was the command （7）module. The astronauts would ride to the moon in the command module and then ride back to earth in it. It was the only part of the spacecraft that could survive the fiery return through the earth's atmosphere.
The （8） lunar module was the second part. It would carry two of the astronauts to the moon's surface. It would later launch them from the moon to rejoin the command module.
The third part of the apollo （9）spacecraft was the service module. It had a rocket engine that the astronauts fired to begin circling the moon. They fired it again to break out of moon orbit for the return flight to earth. The service module carried （10）tanks of （11）oxygen for the flight, and the fuel cells that produced electricity and water the astronauts needed to survive.
Voice one:
There was what seemed to be a minor problem during the ground tests before launch. Two large tanks in the service module held （12）liquid oxygen. The oxygen was the fuel that provided water and （13）electricity for the command module. One of the oxygen tanks failed to empty normally during the ground test. Engineers had to boil off the remaining oxygen by turning on a heater in the tank.
Commander Lovell said later he should have demanded the oxygen tank be replaced. But it seemed to be fixed. So no change was made.
Voice two:
After launch, Apollo thirteen sailed smoothly through space for two days. Controllers on the ground joked that the flight had gone so well they did not have enough to do.
That changed a few hours later. The first sign of trouble was a tiny burst of light in the western sky over the United States. It looked like a far-away star had （14）exploded.
Voice one:
Near the space center in Houston, Texas, some （15）amateur star-watchers were trying to see the Apollo spacecraft through telescopes. One of the groups had fixed a telescope to a television set so that objects seen by the telescope appeared on the television screen.
The spacecraft was too far away to be seen. But suddenly, a bright spot appeared on the television screen. Over the next ten minutes it grew into a white circle.
The (16) observers on the ground had no reason to believe the white spot they saw was made by the spacecraft. They thought it was a problem with the television. So they went home to bed.
Voice two:
It was not a problem with their television. It was a serious problem with Apollo thirteen.
It happened a few minutes after the three astronauts completed a television (17) broadcast to earth. The astronauts heard a loud noise. The spacecraft shook. Warning lights came on. (18) Swinger called to (19) mission control; "Houston, we've had a problem here."
The number two oxygen tanks in the service module had exploded. The liquid oxygen escaped into space. It formed a huge gas ball that expanded rapidly. Sunlight made it glow. Within ten minutes, it was almost eighty (20) kilometers across. Then it slowly disappeared. The cloud was the white spot the observers in Houston had seen on their television.
Voice one:
The loss of one oxygen tank should not have been a major problem. Apollo had two oxygen tanks. So, if one failed, the other could be used. But the astronauts soon learned that the explosion had caused the other oxygen tank to leak.
The astronauts were three- hundred- twenty- thousand kilometers from earth with little oxygen, electricity and water. Their situation was (21) extremely serious. No one knew if they could get the spacecraft back to earth, or if they could survive long enough to return.
Voice two:
The astronauts and the flight control center quickly decided that the lunar module could be their (22) lifeboat. It carried oxygen, water, electricity and food for two men for two days on the moon's surface.
But there were three astronauts. And the trip back to earth would take four days. The men greatly reduced their use of water, food and heat. And they turned off all the electrical devices they could.
Back on earth, space scientists and engineers worked around the clock to design and test new ideas to help the astronauts survive.
Voice one:
Getting enough good air to breathe became the most serious problem. The carbon (23) dioxide the astronauts breathed out was poisoning the air. The lunar module had a few devices for removing carbon dioxide. But there were not enough to remove all the carbon dioxide they created.
Engineers on the ground designed a way the astronauts could connect air-cleaning devices from the command module to the air system in the lunar module. The astronauts made the connector from a plastic bag, cardboard and tape. It worked. Carbon dioxide was no longer a problem.
Voice two:
Now the problem was how to get the astronauts back to earth as quickly and safely as possible. They were more than two-thirds of the way to the moon on a flight path that would take them to a moon landing. They needed to change their flight path to take them around the moon and back toward earth. They had to do this by firing the lunar module (24) rocket engine for just the right amount of time. And they had to make this move without the equipment in the command module that kept the spacecraft on its flight path.
Five hours after the explosion, flight (25) controllers advised firing the rocket for thirty-five seconds. This sent the spacecraft around the moon instead of down to it. Two hours after Apollo thirteen went around the moon, the astronauts fired the rocket for five minutes. This speeded up the spacecraft to reach earth nine hours sooner.
Voice one:
The lunar module was extremely (26) uncomfortable. The astronauts had very little to drink and eat. But the cold was the worst part of the return trip. The temperature inside the lunar module was only a few degrees above freezing. It was too cold for them to sleep much.
They used the electrical power in the lunar module to add electricity to the batteries of the (27) command module. They would need the electrical power for their landing.
Voice two:
The crew moved back to the command module a few hours before landing. They turned on the necessary equipment and broke away from the damaged service module. As the service module moved away, they saw for the first time the damage done by the exploding oxygen tank. Equipment was hanging from a huge hole in the side of the module.
One hour before landing, Lovell, Swinger and Hayes said thanks and goodbye to their lifeboat, the lunar module. They separated from it and sent it flying away from them.
Voice one:
Now, the command module of apollo thirteen headed alone toward earth. It fell through the atmosphere. Its (28) parachutes opened, slowing its fall toward the Pacific Ocean, near (29) Samoa.
Ships and planes were waiting in the landing area. And thousands of millions of people around the world were watching the live television broadcast of the landing. People everywhere cheered as the cameras found the spacecraft (30) floating downward beneath its three parachutes. They watched as it dropped softly into the water.
The apollo thirteen astronauts were safely home.

EXPLORATIONS -- A PROGRAM IN SPECIAL ENGLISH BY THE VOICE OF AMERICA. (THEME)
The summer of nineteen- sixty- nine was a special time in history. That was when men from earth -- American (1) astronauts -- flew their Apollo eleven (2) spacecraft to the moon, landed and returned home safely. The world honored the astronauts as heroes.
Neil Armstrong and Edwin Aldrin were the first to land on the moon. But they were not the last. (2) NASA -- the national (3) aeronautics and space administration -- launched six more apollo flights.
Today, Harry Monroe and kay Gallant tell about the flights that followed Apollo eleven to the moon.
Voice one:
Apollo twelve lifted off only four months after the Apollo eleven flight. Rain had fallen the night before. The clouds cleared, but more rain was expected. Space (4) officials decided the weather was safe enough for them to launch the spacecraft.
Thirty-six seconds after lift-off, lightning hit the huge Saturn five rocket. The Apollo spacecraft lost electrical power to its control system. The astronauts worked calmly to get the power back on. Then lightning (5) struck again. And power was lost again
. The lightning, however, did not affect the Saturn (6) rocket. The rocket continued to push the spacecraft on its path. The astronauts soon fixed the electrical problem. The situation returned to normal. Apollo twelve could continue its flight to the moon.
Voice two:
All three astronauts of apollo twelve were navy fliers. Charles Conrad was the flight commander. Richard Gordon was pilot of the command （7）module. Alan bean was pilot of the moon Lander
. After four days, apollo twelve was near its landing area on the moon. It would land in an area called the ocean of storms. The ocean of storms was about two- thousand kilometers west of the place where Apollo eleven had landed.
Richard Gordon remained in the command module circling the moon. Charles Conrad and Alan bean flew the Lander craft to the surface. They came down near surveyor three, an unmanned spacecraft that had landed on the moon two years before. （8）Surveyor had sent back six- thousand pictures of the moon before it stopped working.
Conrad stepped out of the Lander onto the moon. He described the surface as he walked away from the spacecraft. "Oh," he said, "is this soft! I don't sink in it too Far."
Voice one:
Alan Bean followed Charles Conrad to the surface. The two astronauts collected about thirty-five kilograms of rocks. They left five scientific instruments designed to send information back to earth. And they visited the old surveyor spacecraft.
The two astronauts spent more than thirty-one hours on the moon. Then they returned to the orbiting command module and started back to earth. They landed in the （9）Pacific Ocean, only six kilometers from the ship that waited to rescue them.
Voice two:
The next flight in America’s Apollo space （10）project -- Apollo thirteen -- never landed on the moon. Three days after launch, an （11）explosion damaged the spacecraft. The astronauts lost most of their （12）oxygen. They had to cancel the moon landing and use the moon Lander as a lifeboat. Oxygen from the Lander kept them alive during the long trip back to earth.
Apollo fourteen was launched in January, nineteen- seventy- one. It landed in the hilly Fra Mauro area of the moon.
Fra Mauro is a huge highlands east of Apollo twelve's landing place. A large (13) meteorite hit the area four- thousand- million years ago. The force of the crash spread material from deep inside the moon. Scientists wanted to study this material. They believed it would give them important information about the early history of the moon.
Voice one:
The commander of the Apollo fourteen flight was Alan Shepard. He had been the first American in space. Stuart Roosa and Edgar Mitchell were the other members of the crew; one piece of equipment on apollo fourteen was a light- weight vehicle with two （14）wheels. The astronauts used it to carry tools and cameras while they were on the moon. The vehicle made it possible for them to travel farther from the spacecraft to collect rocks and do experiments. They walked as far as three kilometers from the moon Lander. Even with the two-wheeled vehicle, however, Shepard and Mitchell could not reach one of their goals -- a （15）crater called cone. They did not have enough oxygen to walk that far. They had to return to the Lander.
Apollo twelve and Apollo fourteen produced much new scientific information. And they increased the interest of scientists in the next Apollo flights to the moon.
Voice two:
The last three flights would permit astronauts to stay much longer on the moon. They also would provide a vehicle with four wheels in which astronauts could ride. With such a vehicle, astronauts could explore a much larger area of the moon's surface. The vehicle was called a lunar rover.
The lunar rover was powered by electricity. It could carry two astronauts more than thirty kilometers from the Lander. It could carry more than one- hundred- ten kilograms of equipment. The lunar (16) rover also had a television camera and an antenna for sending color television （17）broadcasts back to earth.
Voice one:
David Scott, Alfred Worden and James Irwin were the crew for Apollo fifteen. They landed at Hadley Rille near the Apennine Mountains, （18）northwest of the place where Apollo eleven had landed.
Scott and Irwin were the first to use the （19）lunar rover vehicle. They made several trips from the landing area to study the surface of the moon. They gathered seventy-six kilos of moon rocks. And they placed a small satellite in lunar orbit before they returned to earth.
The Apollo fifteen astronauts returned safely. Scientists were excited about the moon rocks the astronauts brought back. They named one of them "the (20) genesis rock." it is believed to be more than four- thousand- million years old. Scientists say the rock was created very early in the life of the moon.
Soil brought back contained bits of orange glass. Scientists said the glass came from material created as deep as three- hundred kilometers below the moon's surface.
Astronauts john Young, Thomas Mattingly and Charles duke flew Apollo sixteen to the moon in April, nineteen- seventy- two. Young and duke landed southwest of the Apollo eleven landing place. They spent forty-five hours on the moon. They collected rocks and set up scientific （21）equipment.
Voice two:
Astronauts Eugene Cernan, Harrison Schmitt and Ronald Evans made the last apollo flight to the moon. That was in December, nineteen- seventy- two. Cernan and Schmitt landed in a valley almost directly north of the Apollo eleven landing place. They spent seventy-five hours, in all, on the surface. More than twenty-two hours were spent working outside the Lander.
The astronauts made three trips in the lunar rover to take pictures and collect rocks. The astronauts also left many scientific devices that would continue to report information about the moon.
Cernan and Schmitt lifted off the moon on December fourteenth. Just before leaving, they placed a metal sign on the surface. The sign was to remain forever.
It said: "here man completed his first exploration of the moon, December, nineteen-seventy-two. May the spirit of peace in which we came be reflected in the lives of all（22）mankind."
voice one:
Production of the Saturn five rocket and the Apollo spacecraft ended with Apollo seventeen. America's manned explorations of the moon were completed. It was the end of a special time in human history. It had been the first time people moved beyond their small planet into the huge solar system. Now, once again, the moon was beyond human reach.
