The Wonderful History of Space Exploration In Depth

Have you ever sat in bed at night, staring up at the thousands and thousands of stars up in the dark, black sky? Space exploration, is the exploration of space, meaning it is the study of planets, stars, and exploring new things in space. Thinking back into the ancient days, people used to dream and imagine that they could explore their universe and see what is beyond the small blue planet earth. They're dream was accomplished in the 20th century, and since the ancient times, space exploration has definitely changed for the better. Now, people can practically live up in space, for months, even years at a time.

Lets take a glimpse of space exploration over the past 1,000 years. Space exploration all began in 1957 with the launch of the first artificial satellite. Then four years later, the first human went into space. Two-dozen people have actually physically walked on the moon's surface.

With great advances in technology, the United States has put robots up into space instead of humans; this is when there is too big of a risk for a human to go onto that planet. Unpiloted spacecrafts have also explored some asteroids, comets, and moons.

There are many challenges involved with space exploration, and putting a rocket up into space. One of the things was that the astronauts could not find a powerful enough rocket to send the artificial satellite into space. The satellites needed a swine force and a form of guidance system to steer the satellites onto the right path. There was also a problem with building the satellites; they needed electronic components that were light in weight. They also needed the satellites to be able to stand the vibration and acceleration of the launch. The problem, they needed to find the world's top...
