In 1966, large parts of the earth from mountaintops, balloons, Lunar Orbiter 1 took the above picture of the earth and airplanes. One such person was Katharine Lee as the orbiter came around the moon’s surface. Bates. In 1893 she pondered the inspiring view from Two years later, NASA launched a manned the top of Pikes Peak in Colorado. As a result of that spacecraft, Apollo 8, again to orbit the moon but not experience, she wrote a poem that became the song, to land on it. The spacecraft entered lunar orbit on “America the Beautiful.” However, throughout the history of mankind, no one was able to see the entire Christmas Eve. That evening, the crew transmitted earth until the 1960s. a live television broadcast back to the earth that In that decade, the American and Russian space included the view of our planet shown below. The programs were in full swing. The American goal, to broadcast ended with the three astronauts taking fulfill President John F. Kennedy’s challenge that he turns reading from Genesis 1.

The picture has accomplishments, people had still not seen the entire come to be called the “Blue Marble.” It is one of the planet in sunlight. Because of the angle of the sun, most widely published pictures in history. 6 Unit 1: Welcome to Your World Apollo 17 was the last manned mission to the Now that you have begun seeing the earth in a moon. No human has been far enough away from way that you might not have ever seen it before, let’s the earth since then to take a picture of the whole get the big picture of this planet we share. planet, although unmanned spacecraft have done so.

It has one moon, Some have perceived the fragility of the earth while Jupiter has eight round moons and about 55 as it hangs in the darkness of space. Others have smaller, irregular-shaped moons. pondered how the entire human population— The earth is the third planet from the sun. It which is divided by nations, languages, and cultures orbits the sun at an average distance of 93 million which are often at war with each other—in reality miles. Mercury and Venus orbit closer to the sun, shares a unity of life on this single planet that we while Mars and the other planets are farther away. inhabit together. Another astronaut recalled his thoughts about the millions of people who live each The Goldilocks Planet: Just Right day without enough food or water, of the injustice and conflicts that humans inflict on each other, and We can see God’s wise and loving design of the how this larger perspective on the place we all live earth as the dwelling place for humans in many might help the people of our planet accomplish more ways. The earth has the attributes required to sustain good for each other. life. Some scientists call it the Goldilocks planet. This illustration shows the relative size of the planets but not their relative distance from the sun. Moving from the sun on the left, you can see Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and the dwarf planet Pluto. The sun’s diameter is about ten times that of Jupiter. Lesson 1 - Seeing What You Have Never Seen Before 7 An astronaut aboard the International Space Station took this photo of the earth’s atmosphere with the moon in the background. It is not too big, not too small, not too cold, and also cannot sustain life. The larger planets farther not too hot, but just right. For instance, its distance away from the Sun do not have the atmosphere or from the Sun is just right.

The earth is large enough for The earth’s polar axis is tilted about 23 degrees its gravity to hold the atmosphere, but it is not so from vertical. This tilt is just right.

The earth is an environment Even so, some scientists believe that disasters that supports intelligent, complex life. The earth have a positive impact on the earth’s ecology, such as by redistributing resources and helping regulate the earth’s temperatures. In terms of human response, disasters give people the opportunity to help others in a time of need. This does not mean that disasters are a good thing, but it does mean that good can come even from tragedy. Goats in Morocco have a interdependent relationship with argan trees. The goats climb up into the trees to eat the trees’ fruit. They then spit out the seeds. Lesson 1 - Seeing What You Have Never Seen Before 9 What the Overview Means our being. It is obvious that God designed the earth to be a hospitable home for human beings. When This awe-inspiring overview of the planet on we consider this single inhabited planet, surrounded which we live gives rise to at least two important by a thin atmosphere, in the vast reaches of space, central truths. One, the earth has been home for it does seem fragile. On the other hand, the earth every human that has ever lived. Since we share this is strong and enduring. It gives us what we need, planet and have no other choice about where to live, and it has survived all of the natural and man-made we need to respect and understand one another and disasters that have occurred. Our responsibility is to the planet on which we live. live on the earth in such a way that we honor its The second and even more important central Maker. truth is that the one God made the one earth for The Scriptures portray God as Creator of heaven all of mankind, and He sent one Savior to redeem and earth.
