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 aerospace engineers, and engineering facilities to adopt new standards of testing and reliability. On the ground, the engineers were trying to make communication stations so there is two-way communication between the astronauts and the ground patrol.Then came the world of piloted space flight, this new creation brought many new difficulties and problems with it. Piloted space flight became even more frightening for the Apollo missions. The Apollo missions were about sending astronauts to the lunar surface and back. Some of the Apollo missions were successful, however, a few missions were sadly unsuccessful. The long duration of space flights became logical, because of the creation of a Soviet Union and U.S. space station. Now present day in the United States, people are more concerned about maintaining the astronauts health during a mission.The mother of all ancient satellites was the Sputnik 1, which was the first artificial satellite to be sent up into space by the Soviet Union in 1957. The Soviet cosmonaut Yuri Gagarin was the first person to go up into space in 1961. In comparison, from the 1950's to the 1990's, dramatic improvements in space have occurred, in overall, the main advances were in technology and new records.The...
