Space Science and Technogy: Unmanned Space Exploration

During the Space Race, the first orbital satellites were sent to outer space. Today, Americans can communicate, predict the weather, and study geodetics because of the satellites that first orbited in space.All satellites and space probes carry specialized radios receiving and transmitting equipment for guidance and control purposes as well as relaying data from space to Earth. Without the first satellite transmission of a human voice in 1958, communication would not be as efficient (Rabinowitch, 1963).

In the end, there are a myriad of problems that face space exploration. Some of them are small

The world’s first satellite was launched into space by the Soviet Union and was called Sputnik 1. The Soviets launched this satellite on October fourth, 1957. As a result from Sputnik 1, NASA began its own operations called the explorer missions on October first, 1958 (https://history.nasa.gov/factsheet.htm).NASA had employed 8,000 workers and not to long after NASA was up and running America launched explorer 1 on January 31, 1958 (https://www.jpl.nasa.gov/missions/explorer-1/). The launching of explorer 1 was successful and opened new doors for accomplishments for

One outgrowth of the Cold War between the United States and the Soviet Union was the “Space Race.” The Space Race was a competition between the United States and The Soviet Union to become the first world superpower to have the best technology in space. After World War II, the United States and the Soviet Union understood how important experimentation with rockets would be to their military strength going forward. Recognizing their own limitations, both countries enlisted the world’s foremost rocket scientists from Germany to help with their research. Not long after, both the United States and the Soviet Union were making great strides in rocket technology. By 1955, both countries announced that they were close to launching satellites into orbit. The two countries took one another’s claims as threats to their national security and the Space Race was born. The Space Race was regarded as critically important by both the United States and the Soviet Union because the outcome would show the world once and for all which country reigned

Sputnik was about 10 times the size of the first U.S. Satellite, The U.S. government, military, and scientific community were all caught off-guard. The Soviet Sputnik organisation had 4 satellites, 3 of them reached Earth Orbit.(“sputnik.”-Windows)

Satellites orbiting the Earth today as a result of the developed technology give us GPS, television, weather data, and rapid international communications. However, the consequences were also immense. The space race cost many lives and billions of dollars. The Apollo program alone cost $25 billion.

A lot of people ask what a satellite is or why is it import. Well if it wasn’t for satellites you would have no Wi-Fi or internet! So let’s get right in to a specific one. Sputnik! It was made by a company in Russia that wanted to see more and go beyond things. On October 4, 1957 the Soviet Union launched sputnik 1, the first manmade object to orbit the entire earth. It was the first artificial earth satellite. According to

As these orbital objects continue to add up, space is growing all the more crowded, and presently, space enthusiasts are becoming increasingly concerned with the junk left by defunct satellites, spent rocket stages, and even small bits of trash leftover from old explosions. In recent years, attention-seeking news media developed a controversy about the topic of space junk, creating a misinformed and panicked populous which distrusts the information provided by space enthusiasts and legitimate space agencies. However, when provided the right information, both sides can agree that space junk is an issue that needs to be handled, but not one that will cause a major

The Cold War began the use of space for war advantages. At the end of World War II, the dropping of the two atomic bombs changed the way war was fought forever. The Cold War brought the need for gathering intelligence on enemy countries driving the Cold War into the space race developing artificial intelligence, satellites, which would be used for military use including spying and reconnaissance. Many government agencies were formed and created the Corona Satellite having the most effect on the Cold War intelligence gathering. Without the use of satellites during the Cold War and agencies formed for foreign surveillance, the satellites used daily for television, GPS, photography, reconnaissance, and space exploration would not exist. Satellites

In the United States, Sputnik was an unwelcome surprise. The US and Soviet Union were 10 years into the cold war, and the US didn’t want the Soviet Union to gain the upper hand on anything. To the US, space seemed like a new journey in America’s mission to expand its horizon farther than the Soviet Union. Therefore, On January 1st, 1958 the US launched its first satellite into space, The Explorer. This satellite was designed by rocket scientist Wernher Von Braun. 3 months after this the US launched another satellite call Vanguard into space. This satellite transmitted data for 3 years after its launch.

Before the launch of the Soviet Sputnik satellite in 1957, the United States had worked towards the same goal. The Eisenhower administration quietly created a project that involved satellites to orbit around the earth for the sole purpose of surveillance. The information collected would be used to avoid armed nuclear conflict with the Soviet Union. Many in the military were convinced that space could become a place of military battle. Many of these ideas were kept secret from the public and thus the Soviet’s accomplishment created the Sputnik crisis. Ultimately Eisenhower was forced to respond with the launch of Explorer 1. By early 1958 the administration’s space advisor James Killian created new civil space agency called the National Advisory Committee for Aeronautics (NACA). Its mission was to control non-military missions for space exploration. On October 1, 1958, NACA was disbanded, and transformed into the National Aeronautics and Space Administration

In 2009 there was an unfortunate case where a U.S. communications satellite collided with a Russian satellite causing a massive explosion and creating a lot of space debris. Unfortunately space collisions often happen due to the debris in space. In 1980 only 5000 pieces of debris were tracked and scientists did not think this was such an important matter. In 2010 the space debris was over double the amount it was in 1980. There was over 15,000 pieces of debris in orbit which caused scientists to worry. Engineers and scientists came together and decided to build what we call the space fence to detect objects before they can come in contact with satellites. Radars and energy were imperative

The space debris implies all man-made objects in space and their fragments, which are already defective and will never be able to serve any useful purposes. They include old artificial satellites, the upper stages of space launch vehicles, the fragments of exploded rockets, and so on. All these objects form dense layers around the Earth. In October 1979, the Johnson Space Center in the United States created the first specialized unit for research on space debris category at the initiative of NASA (Nelson 2014). Then, the international community has recognized the growing danger of space debris and the urgent need for measures to prevent its formation. Finally, it created the Inter-Agency Space Debris Coordination Committee (Nelson 2014). It is the most influential organization, which covers the full range of issues associated with space

There are a million satellite that are orbiting Earth right now but i choose on called Aeneas was first launched on September 9, 2012. The owner of the satellite is called Department of Homeland Security.Aeneas's purpose for orbiting Earth is to do Technology Development. This satellite is 642.53 km above EArth and is going about 7.54 km/mi. There are more satellites that are going around us that we don't know about yet.

In more than 40 years of space activities some 3800 launches led to about 25000 observable space objects larger than 10 cm of which 8300 were still in orbit by September 1997. Only 6% of the catalogued orbit population are operational spacecraft, while 50% is said to be due to "decommissioned satellites," spent upper stages, and objects such as launch adapter and lens covers, which are mission related. The other 44% is originating from 140 on-orbit fragmentations. These events have been the main source that has generated a population of objects larger than 1cm on the order of 70000 to 150000.
