As the rocket rose, rookie astronaut Anders was startled how violent and noisy the experience seemed, especially when compared to the simulators. He was jerked from side to side as the Saturn 5's engines far below kept adjusting the direction of their thrust to keep the rocket vertically balanced.

This in turn whipped the rocket's tip, where the astronauts sat, back and forth like an antenna.
To Lovell and Borman, however, the ride seemed almost comfortable compared to past experience. Lovell thought it was unbelievably noisy. Borman

later wrote that "the ride was incredibly smooth; compared to Apollo 8, Gemini 7 [his previous space flight] had traveled over a few hundred potholes."

For just over two minutes the five F1 engines of the first stage pounded them upward, quickly accelerating them to a speed of over 6,000 miles per hour and an altitude of forty miles. Then, as planned, these engines cut off, the first stage was blown free, and after a moment's pause, the five J2 engines of the second stage kicked in. A moment later the rocket's escape tower and capsule shroud blew off. If they wanted, the astronauts could now look out their windows.
Not that they were really interested. When the first stage had cut off, all three men had been flung hard forward in their harnesses, then thrown backward violently when the second stage ignited. Anders thought he would fly straight into the instrument panel.

Borman worried about the strain on the rocket boosters. Lovell was merely exhilarated.
For six more minutes the second stage's smaller engines hammered them into the sky. Without the weight of the first stage to hold it down, the Saturn 5 accelerated much more quickly, its speed rising to more than 15,000 miles per hour. Then, at an altitude of over one hundred miles, these engines

cut off and the second stage blew away, joining the first in its long fall down to the Atlantic Ocean.
Now the third stage ignited. For about two and a half minutes it burned, driving the spacecraft ever higher and faster. Only eleven and a half minutes after liftoff the third stage cut off, and exactly as planned, Apollo 8 was in a 115-mile orbit, moving at 17,400 miles per hour.
Other space missions would have now shed the third stage, becoming a space capsule just large enough to hold crew and supplies. In order to escape earth orbit, however, Apollo 8 needed its third stage. When refired, its fuel and engines would increase the spacecraft's speed by another 7,000 miles per hour.
In fact, that third stage could send the astronauts and their little space capsule as far as anyone wanted them to go. If NASA had wished it, those engines could have transported the Apollo capsule to any point in the solar system, from the moon to Pluto, and even beyond.
This time, however, the spacemen were merely going to the moon. For now, that would suffice.

For the next two orbits, both ground stations and astronauts labored hard to confirm that all systems checked out. At mission control, astronaut Mike Collins sat at capsule communications (or capcom for short), relaying information to and from the capsule. Collins had originally been assigned to this mission, and had been training for it since 1966. Then, in 1968, he began noticing that his legs no longer worked quite right. He found that his left knee sometimes buckled under him for no reason. He experienced a strange tingling and numbness in his left calf. The leg felt hot and cold at the strangest times. Very quickly he realized that these sensations were spreading.
Tests revealed a bonespur pressing against his spinal cord. Collins was immediately grounded, scrubbed from Apollo 8 and replaced by his backup Jim Lovell. And even though Collins's July operation was a complete success and by December his back had healed, he was still stranded on the ground. To his intense frustration, Collins found himself designated as one of the three astronauts assigned to handle the ground-to-capsule communications.

He sat there, both enthralled and envious of the men in orbit.

Cliff Charlesworth, the mission's prime flight director and the man whose job was to make all final decisions while on duty, stood nearby. Charlesworth, thirty-seven, was a quiet laconic Mississippian, known for his cool head and calm, deliberate manner. He now ''called the roll," mission control jargon for going down the line of consoles and asking each man if everything in his department was "go," or "no go." One by one the men said "Go." Charlesworth turned to Collins and told him to let the astronauts know.
In a calm voice that contradicted the significance of his words, Collins announced that the astronauts now had permission to leave the earth. "Apollo 8, you are go for T.L.I." T.L.I. stood for trans-lunar injection, the five minute rocket blast that would send them toward the moon, accelerating their spacecraft to a speed of over 24,000 miles an hour, 7,000 miles an hour faster than any human had ever traveled.
Five seconds before ignition their primitive on-board computer (less powerful than the least sophisticated hand calculator available today) asked the astronauts one more time if they wished to abort. Jim Lovell calmly keyed in the command for the computer to proceed. At 9:41 AM the engines fired, burning more than eighty tons of fuel for five minutes and seventeen seconds. As their speed increased, Lovell called out Apollo 8's increasing velocity in feet per second: "Coming up on 28,000 . . . . 30,000 . . . 34,000 . . . 35,000 . . ."
Then the engines cut off, and they were flying away from the earth at 35,452 feet per second, or 24,171 miles an hour. If an ordinary jet airliner took off at that speed it would reach normal cruising altitude in one second.
At mission control Mike Collins told them, "We have a whole room full of people that say you look good." Chris Kraft couldn't resist exclaiming into the radio, :You're on your way you're
really
on your way!"
They were no longer in earth orbit. Apollo 8 had become the first manned vehicle to break the bonds of earth.

For the next half hour the three astronauts had little time to consider the magnitude of their journey. The third stage would automatically separate from the capsule in less than twenty-five minutes, and they had to be ready.

Borman and Lovell urgently scanned the many dials on the instrument panel, reading off the numbers for Anders to check against the flight plan.
Then, with what Frank Borman described as "a bone-jarring shock,"

the third stage blew free. For ten minutes Borman struggled to maneuver the command module so that the astronauts could spot the stage in their windows. Finally, he swung the ship around and Jim Lovell said, "There she is . . ." only to have his voice trail off in awe.
The third stage was clearly visible, barely five hundred feet behind them. Behind it, however, loomed the entire sphere of the earth. Their speed was so great that only forty minutes after leaving earth orbit, the planet had shrunk enough to be entirely visible within a single window.
All three men scared in silence. Even as they watched, the earth visibly shrank, the black velvet of space growing around it. To Lovell, the experience felt like he was driving a car into a dark tunnel: looking back he could see the light at the opening dwindle to a small speck behind him. Borman thought "this must be what God sees."
22
Anders was surprised at how delicate and pretty the earth looked.
After a minute of staring at the earth, Borman shook himself awake and decided someone should let the ground know. "We see the earth now, almost as a disk."
On the earth, Mike Collins had no idea how powerful that image looked to the astronauts. "Good show," he said. "Get a picture of it."
Lovell attempted to describe what they saw, outlining how he could see Florida, Africa, Gibraltar, and even most of South America. In one glance he could see the entire Atlantic Ocean.
Collins still hadn't quite sensed what the astronauts were seeing. He asked Lovell what window he was using, and again urged them to take pictures.
For thirty more seconds the three astronauts stared silently at the earth. Whatever their expectations for this journey, they had not anticipated this kind of vision. The earth's atmosphere lent it a translucent quality, almost as if it were glowing. And even as they watched, they could see it shrink in the surrounding darkness. In the ten minutes since Jim Lovell had first spotted it, they had moved over 3,500 miles farther away.

in less than three days, these men would reach lunar orbit. For a brief twenty hours they would circle the moon ten times, hold two press conferences, and generally try to relate to the awed world behind them their impressions of the first human exploration of another planet. And they would do this on Christmas Eve, the most significant spiritual holiday for almost a third of the world's population.
What would they say?
Surprisingly, the three astronauts had already chosen the theme for their most important message. Borman had found the words, and the others had completely agreed. All three knew where they stood in the cultural and political war that had been ongoing since the end of World War II and had become especially violent in the last twelve months. All three wished to contribute their thoughts on the matter.
Nonetheless, the incredible experience itself the vastness of space, the desolation of the moon, and the lovely blue-white lure of earth shrinking steadily behind them exerted its own inexorable command. Before these three men returned to earth, their experience and the words they spoke would have an influence on the world far beyond anything any of them had expected, or possibly even wanted.

"We Will Bury You!"
Borman
The ovens were still, there. So were the gas chambers, the fences, the towers, the bleak dormitories. The metal sign on the gate still said "Work will set you free" in German. In the center of the Dachau concentration camp the gallows still stood, silent witness to the death of hundreds of thousands.

The occupants, however, were no longer starving Jews condemned to mass slaughter. The year was 1949, and the refugees were from East Germany. Since the liberation of the concentration camp at the end of World War II, Dachau had been used first to shelter German prisoners of war and Soviet army deserters. In 1946, these deserters rioted. Ten actually killed themselves rather than be repatriated to the Soviet Union as per the Yalta accords.

Since then the camp had housed tens of thousands of German refugees who were fleeing the Soviet zones of occupation.
