Kennedy Space Center

  For those who are full of curiosity and spirit of exploration, the Kennedy Space Center is a mecca for intellectual exploration and a starting point for a future world. Space exploration and interstellar flight are fields that every developed country will pay attention to and attach importance to, and this field is related to the future destiny of mankind. Kennedy Space Center is the focus of attention of aerospace experts and space enthusiasts all over the world, and every action here will have a profound impact on the future of mankind. In the words of NASA, their goal is: “To understand and protect the planet we live in, to explore the universe and extraterrestrial life, and to inspire our next generation to explore the universe.” Since Columbus discovered the American continent, in addition to the North Pole And the Antarctic investigation, human beings are no longer satisfied with the territory of the earth, the vision of exploration has already surpassed the horizon, and they are no longer satisfied with the observation of telescopes, but want to try to get out of the dream of the earth.
  From Orlando along the highway–m to Cape Calaveral, the weather is very good, cloudless, blue sea and blue sky. This place is actually a small island connected to the mainland, connected by several bridges in the middle, and the vast Atlantic Ocean outside. Seagulls are flying around in the parking lot, and the smell of the sea is on the front. The entire outer island is very large, the launch area and the assembly area are far apart, and tourists must take a bus to visit. We stopped at a visitor center that displayed a disused rocket engine, the casing peeled away to reveal the sinuous pipes and giant nozzle inside.
  Climbing up the observation tower, the huge launch pad in the distance is the famous Launch Tower 39, the world’s most famous space launch center. Tower 39 was built specifically for the Apollo program, and the launch center includes a workshop capable of assembling the large Saturn V rocket, and a transporter capable of transporting 5,440 tons of items. Kennedy Space Center has a total of two “crawler transport vehicles”, each weighing 2721 tons. They are slow, requiring a five-hour “crawl time” from the workshop to the launch site. Technically speaking, the 111-meter-tall Saturn V rocket has to overcome a certain slope to the launch site on its own. It’s already an amazing technical achievement.
  Then, we came to the Saturn 5 Museum, because of its important role in the Apollo program, this behemoth was also named “Moon Rocket”. Only when you come here can you experience the magnificence of this behemoth for yourself. There is a giant Saturn 5 rocket, Takakawa rice, 10 meters in diameter, divided into 3 stages. So far, this is the largest rocket ever built by mankind. Its height, thrust, and pre-flight weight all make it a well-deserved giant rocket. When the rocket launched, the ground tremors could be felt 80 kilometers away.
  Standing under the 5 giant nozzles of the first stage of the Saturn 5 rocket, you can feel the spirit of interstellar flight, and find the feeling that can only be experienced in science fiction movies. Here is the world of machines, with all kinds of curved and intricate pipes, bronze casings, and a metallic glow of pale blue. You can only sigh that interstellar flight is so complicated that it is incredible that humans can build such complex and huge machines. Next to the Saturn 5, there are replica lunar modules, lunar rovers, etc., and a lunar stone taken from the moon is also displayed here.
  From the Saturn 5 Museum, we came to Rocket Park. Imitations of various rockets used in American history are stacked here. Various types of rockets are displayed, most of them standing upright, forming a spectacular scene one by one. Among them, there are also some large rocket engines, the fairing is removed, and the curved copper pipes are exposed, making people feel as if they have come to the future world and are in an alien planet.
  Next to Rocket Park is the Space Shuttle Discovery. This space shuttle is a one-to-one replica that looks and looks exactly like the actual space shuttle. But it’s just an exhibit, not a real space shuttle. Visitors can walk into the “Exploration” from the adjacent platform to explore its internal structure. There is a large cargo compartment inside, which is used to load various satellites and related components, etc., and there are manipulators inside, which can complete large-scale installation tasks.
  In addition to the scientific research mission, Kennedy Space Center is also responsible for publicizing the new achievements of spaceflight and space exploration to the public. They have a dedicated space exploration TV channel, which is jointly responsible for them and Disney, introducing various A program about space and astronautics. Through these activities, NASA has won the support of the American public and increased its clout in securing funding from Congress.
  On May 25, 1961, President Kennedy announced to Congress on behalf of the government: “In 10 years, an American will be sent to the moon and returned to the ground.” This is the most famous Apollo moon landing program in the 20th century. The Apollo program was carried out a total of 17 times. The first plan failed, resulting in the death of 3 astronauts, and after 8 years of experiments and preparations, the historic moment finally came. On July 16, 1969, the Apollo 11 lunar module landed on the moon, the first time humans set foot on a planet other than Earth. Astronauts Armstrong and Aldrin became the lucky astronauts. When Armstrong set foot on the moon, he said: “This is one small step for me, but one giant leap for mankind.”
  The success of the moon landing proved that contemporary engineering technology has prepared the conditions for mankind’s dream of exploring the universe, Human development has entered an era of rapid change. After Apollo 11, a group of astronauts landed on the moon. The last person to land on the moon was a geologist and the first scientist to land on the moon, Harrison Schmidt.
  Of course, the political significance of the Apollo program outweighed its practical value. The immature electronics and computer technology of that era doomed the project to be much ahead of its time. This plan greatly promoted the progress of American engineering technology and objectively promoted the super-large-scale development of computer technology. More importantly, the Apollo program stimulated their enthusiasm for exploration and inspired the dream that began in the Verne era. This dream also inspired more outstanding young people to devote themselves to exploring the mysteries of the universe.
  Space exploration needs to follow the principles of science: there must be both grand plans and practicality; scientific goals and huge overdrafts of human and material resources must be avoided. Therefore, after the implementation of the moon landing plan, the Americans did not continue the project, but carried out more scientific exploration. Generally speaking, their efforts are mainly focused on two aspects: one is to launch probes to conduct deep space exploration, to examine in detail the conditions of other stars in the solar system, and to search for stars similar to the Earth’s environment; the other is to build the International Space Station, deep space The purpose of exploration requires the establishment of a spaceport similar to a “dock” outside the earth, to get rid of the gravity of the earth, and to build a transit station in order to carry out the mission of interstellar flight.
  NASA built the world’s first space shuttle in 1979: the Columbia. Later, Challenger, Discovery, Atlantis and Endeavour were built. These shuttles are reusable, marking a new phase in space exploration. But the cost of space exploration is very high. So far, 2 of the 5 space shuttles built have crashed and exploded, killing 14 astronauts, which is a heavy blow to the US aerospace industry. The “Challenger” crash grounded the U.S. space shuttle for three years, and the “Columbia” crash grounded it for another five years.
  February 25, 2011 was the last flight of Discovery. After the mission, it will be sent to the Space Museum in Washington as an exhibit. Discovery is the oldest space shuttle in the United States. It began its first space flight in 1984 and has traveled 21.3 billion kilometers in space. The mission of this flight is to deliver the first humanoid space robot “R2” to the International Space Station. The robot has a human-like appearance, with a head, torso and hands. The 4 infrared cameras on the head are used to perceive distance and depth, and have the function of stereo imaging.
  Endeavour and Atlantis were also sent to the museum after their missions in April and June 2011. It also means the end of the era of the American space shuttle. When “Discovery” took off for the last time, many tourists and space enthusiasts came from outside the launch site. They gathered here to wave goodbye to “Discovery” for the last time. This space shuttle has been with them for more than 30 years. years have passed.
  On the square of the Kennedy Space Center stands a building like a radar antenna. In fact, this is not a radar antenna, but a huge commemorative plaque. It is not a solar panel, but a huge granite, engraved with the names and faces of the astronauts who crashed in spaceflight. Every night. When the time comes, the spotlights on the back of the granite come on, and these hollowed-out names glitter under the night.
  I stopped for a long time in front of the astronaut commemorative plaque, and looked closely at everyone’s faces, and they all smiled at us. Space exploration is exciting, every discovery excites people, and every achievement is a reflection of human imagination and technological prowess.
  In the 18 billion years since the universe was born, and the 5 billion years since the solar system was born, how many thrilling events have happened. As a human being with only 5,000 years of civilization history, we know too little. However, standing on the azure planet Earth, we have extended our telescopes to the depths of 10 billion light-years of space; we are sending our craft to the edge of the solar system: we have been able to study the evolution and Change, this must be said to be the miracle of nature and the pride of mankind!
