EXPLORATIONS -- a program in Special English by the Voice of America.

(MUSIC)

Today, Harry¹ Monroe and Tony Riggs report about America's second manned space program, Gemini. Two astronauts flew on each flight. Gemini's purpose was to bring the United States closer to its goal of landing² astronauts on the moon.

VOICE ONE:
　
The launch³ of Gemini 3 carrying Virgil Grissom and John Young

The astronauts of America's first manned program, Project Mercury⁴, made six successful flights. They proved that people could survive the hostile⁵ environment of space.

In nineteen sixty-five America's space agency⁶, NASA, was ready to begin its second manned program. NASA called it Gemini. The program was named for the two stars Castor and Pollux in the star group Gemini. The Gemini program would send two astronauts at a time into space.

Gemini would test the men's ability to live and work in space. Gemini, it was hoped, would move America closer to its goal of landing astronauts on the moon.

VOICE TWO:

The first Gemini spacecraft would carry astronauts Virgil Grissom and John Young. Its Titan rocket could lift three times as much weight into space as the Atlas⁷ rocket used for the Mercury flights. The launch took place without a problem on March twenty-third, nineteen sixty-five.

Grissom and Young orbited⁹ the Earth only three times. But they did something that the Mercury astronauts had not been able to do. They changed their orbit⁸ while in space. The Gemini astronauts were developing the control that would be needed for a trip to the moon.

Less than two months later, James McDivitt and Ed White went into space on the second Gemini flight. Their flight included several experiments. But one seemed almost unbelievable -- a space walk.

Ed White would leave the protection of the spacecraft and move out into the unknown emptiness of space.

VOICE ONE:

When it was time for him to leave the spacecraft, this is what the world heard: "Roger, Flight, we're GO." Those were the words from the flight director on the ground.

Then a voice came down from space. "He is ready to leave right now," called McDivitt. The astronauts had removed all air pressure from the spacecraft. Only their special space clothing would provide the air pressure they needed to stay alive.

VOICE TWO:
　
Ed White during the first American spacewalk

Slowly, Ed White moved out the open door. He was tied to the spacecraft by a long rope. He floated out and away from the spacecraft. Millions of people listened as he said: "This is the greatest experience. I am looking down right now. And it looks like we are coming up on the coast of California."

At space agency headquarters¹⁰, doctors studied his medical condition as the information was being sent back to Earth. They said that being outside the spacecraft did not seem to affect him.

VOICE ONE:

It was time for Ed White to end his space walk. James McDivitt had to beg him to return. White was having a wonderful time. He wanted to stay out longer. Finally, he climbed back inside. He had floated around in the emptiness of space for twenty-one minutes.

Then a problem developed. The door of the spacecraft refused to shut tightly¹¹. The astronauts' clothing protected them during the flight. But what would happen during re-entry? James McDivitt had to try to repair the door.

(MUSIC)

VOICE TWO:

Scientists always knew it would not be easy for humans to work in the weightlessness of space. Each time an astronaut puts pressure in one direction, their body moves in the opposite direction. There is no gravity to hold them in place.

NASA scientists had tried to solve the problem by designing new tools for use in space. McDivitt tried one of the new tools. It worked. He was able to repair the broken door so it shut tightly.

VOICE ONE:

Solving this problem, however, created a new one. The astronauts had planned to re-open the door during their four-day flight. They had planned to throw away materials they no longer needed, including uneaten food. But now they decided¹² it would not be wise to re-open the door.

Soon, the inside of the spacecraft began to fill up with all kinds of junk. McDivitt and White had to learn to sleep and work as things floated around their heads.

VOICE TWO:

On the sixty-second orbit, the astronauts prepared to return to Earth. They fired the spacecraft's control rockets. The spacecraft slowed and began to re-enter the atmosphere. It landed safely in the Atlantic Ocean.

Rescue helicopters reached McDivitt and White within seven minutes of landing. The two American astronauts were in excellent condition. They had made the first space walk. And they had proved that people could both live and work in space.

VOICE ONE:
　
Charles Conrad and Gordon Cooper walk to the Gemini 5 launch pad¹³

The next Gemini launch was planned for just two months later. Gordon Cooper and Charles Conrad were to spend a record eight days in space.

Soon after the launch, Cooper and Conrad noted¹⁴ a problem that almost ended their flight early. They discovered a drop in pressure in the fuel cells that supplied electricity. These fuel cells powered the communications and computer systems. And they were very important to the environmental control systems in the spacecraft.

VOICE TWO:

Gemini's flight director decided to reduce the use of power on the spacecraft, instead of ending the flight early. Cooper and Conrad turned off the radar¹⁵, radio, computer and even some environmental control systems. The spacecraft floated silently through space.

Suddenly the power began to increase. The astronauts turned the systems back on. By the third day in orbit, all was normal again.

Then another problem developed with the same fuel cells. The cells created electricity by mixing hydrogen¹⁶ with oxygen. The process also produced some water. But the fuel cells were producing too much water. Containers that held the water were filling up too fast.

NASA was worried that the extra water could destroy the power supply needed for the spacecraft's return to Earth. So, Cooper and Conrad again turned off most of the power in the spacecraft.

VOICE ONE:

Again, the spacecraft floated almost silently above the Earth. Communications were few. Cooper and Conrad could not do any of the planned experiments. But each day, they set another record for surviving in space.

Eight days after their launch, Cooper and Conrad fired the control rockets and re-entered the atmosphere. They had circled the Earth one hundred twenty times. They had seen one hundred twenty sunrises and sunsets. They had traveled more than five million kilometers. They had proved that people could live and work in space for the time it would take to get to the moon and back.

(MUSIC)

VOICE TWO:

Now, it was time for Gemini Six to make its mark in history. Walter Schirra and Thomas Stafford were the astronauts. Schirra had been the pilot on an almost perfect Mercury flight three years before. Stafford was from the second group of American astronauts.

They were to make the first effort at a space chase¹⁷. The two men would chase another object orbiting¹⁸ Earth, a satellite. They would try to move their spacecraft as close as possible to the satellite. This move had to be successful before any moon landing could be attempted.

But things did not go as planned. The satellite that Schirra and Stafford were supposed to chase apparently¹⁹ exploded after it was launched²⁰. NASA postponed²¹ the flight of Gemini Six.

VOICE ONE:

Space agency officials had to find the reason for the failure of the target satellite. That would take valuable time. So, they decided to launch the next flight, Gemini Seven, instead of waiting.

The astronauts for that flight were Frank²² Borman and James Lovell. They planned to set another record -- fourteen days in space. It would be the longest, most difficult flight yet.

Then NASA considered another plan.

There was nothing wrong with the Gemini Six spacecraft. So, NASA announced that Gemini Seven would lift off on December third, nineteen sixty-five. Then, if everything else was ready, Gemini Six would be launched a few days later. It would attempt to meet in space with the orbiting Gemini Seven.

VOICE TWO:

NASA quickly added a warning to its plan. There was less than a fifty percent chance of success. But Americans were hopeful. If the plan succeeded, it would be the greatest space act since manned flights began.

We will continue our story of America's Gemini space program next week.
