Space And Its Unknown To Orbit Earth example essay topic

In our history many great things have happened. Weave been inventing and exploring things since day one. Many of these things that we discovered or invented we thought would never be possible in earth's life time. But they exists now, today, they are used by almost every human being and there are many more incredible and unmanageable things to come and aid us in every day life. One of the most interesting things to me would fall under exploration and inventing. You are about to venture in to the history of space and learn how man and mans objects have gotten there.

The exploration in space dates back over 40 years ago, January, 31 of 1958 to be exact. On this date Explorer 1, which was the first U.S. satellite to be fired in space and its unknown, to orbit earth. It lifted off from Cape Canaveral using a modified Jupiter-C rocket called ABM A-JPL. It carried a scientific experiment of James A. Van Allen, and discovered the Earth's radiation belt. Along with defeat and triumph also come disappointment and failure. In March 5 of 1958 Explorer 2 was launched by another Jupiter-Crocket and failed to reach orbit.

October 1, 1958 NASA was founded, taking over existing National Advisory Committee on Aeronautics and only ten days later. S. - IGY space probe was launched to a incredible height of 70,700 miles. On March 3 of 1959 Pioneer 4, anU.S. -IGY space probe is launched by a Juno II rocket, and achieves an earth-moon trajectory, passing within 37,000 miles of the moon. It then fell into a solar orbit, becoming the first U.S. sun orbiter. About a year later Tiros 1 was fired into earth's orbit and became the first successful weather satellite for the United States. Then on August 18 of the same year, 1960, Discoverer XIV was launched and became the first U.S. camera-equipped Corona spy satellite. On July 14, 1965, They U.S. Mariner 4 returned the first close-range images of Mars.

The above paragraph explains some of the earliest satellites, spy satellites, and probes that were sent into space to explore the unknown and the " Impossible'. May 5 of 1961 Mercury Freedom 7 carried Alan B. Shepard, Jr., who was the first U.S. astronaut in space, in a suborbital flight. This United States' first manned space flight project was successfully accomplished in a 4 2/3 year period of dynamic activity. During this time they saw more than 2,000,000 people from many major government agencies and much of the aerospace industry and combined their skills, initiative, and experience into a national effort.

Also during this 4 and 2/3 period six other manned space flights were accomplished as part of a 25-flight program. These manned space flights were accomplished with complete pilot safety and without change to the basic Mercury concepts. I twas shown that man can function ably as a pilot-engineer-experimenter without undesirable reactions of normal body functions for periods up to 34 hours of weightless flight. And so we continue or fight through this history of space exploration. February 20 of 1962 Mercury Friendship 7 lifts off with John H. Glenn, Jr., who was the first American in orbit, and orbits the Earth three times. In July 31, 1964 U.S. Ranger 7 relayed the first close range photographs of the moon.

Probably more spectacular than man orbiting earth would be space walk. The united state accomplished this in 1965 on Jun 3rd. Edward White II made the first U.S. spacewalk from space vehicle Gemini 4. The duration of the spacewalk was 22 minutes, which was the longest up to this date. December 4 of 1965 was a great day. Gemini 7 was launched carrying Frank Borman and James A. Lovell, Jr., which made 206 orbits around Earth and proving a trip to the moon possible.

A year later the US does the next best thing from sending a person to the moon and sent Surveyor 1 which was the first U.S. spacecraft to soft-land on the moon. December 21, 1968 Apollo 8 and its four crewmember's were the first Apollo team to make orbit around the moon, they actually made ten orbits around the moon. July 20, 1969 only 30 years ago Neil Armstrong and Edwin Aldrin, Jr. make the first manned soft landing on the moon. Not only this they were the first moonwalk and this trip was made possible because of Apollo 11 mission. Skipping a head a few years we find that on September 3, 1976 Viking 2 landed on Mars at the Plain of Utopia, where it discovered water frost. We have come a long way since 1858 to 1976 and we are now going to jump into the last nine years of our history.

April 24, 1990 Space shuttle Discovery embarks on mission STS-31, deploying the Edwin P. Hubble Space Telescope. In September 26 of 1996 the United states came back holding the record of staying in space for the longest time. This could be the key to getting us farther places leading to more exploration, only time will tell. Towards the end of 1996 The US started to survey mars and gather information from it. July 4, 1997 -The Mars Pathfinder arrived at Mars and took pictures of the planet.

The data collected encourages scientists to believe the planet may once have harbored life. The planet is much more like Earth than previously suspected. On the date of December 21st 1998 the Us Announced that Chandra X-Ray Observatory would be putin to space. This made it the largest object put into space and was made to help scientists understand the structure and evolution of the universe. And last but not least on April 16, 1999 NASA launched Landsat-7. It will locate urban 'hot spots' that may alter local climates, and monitor the effects from deforestation in Central American rain forests.

Here is a quote that I found interesting. I will write down the quote and tell who said it and why I chose this quote. The first quote is written by JFK. 'We choose to go to the moon in this decade to do the other things... Not because the yare easy but because they are hard' I chose this quote because it is say that we strive d beyond the easy and imaginable to the hard and unimaginable. Above you have read many things that the US has discovered and explored in space.

I picked this topic because I like space and I enjoy learning about it. It is nice to day dream that someday we might be living on some distant planet. These events and people were very important to our history because if it was not for them we would not know anything about space. We would also not be one step closer to be living on another planet. Thank you for reading. Bibolgraphy =
