《探索太空》英文讀后感3000字 1
Looking at dark sky at night for a while, you may see a red star. It has dazzling color. People call it “Mars”. In the solar system, beyond the third planet, the fourth one is “Mars”. It is a planet which is far away from Earth, about 2 hundred million kilometers on average. It is so charming that many scientists and people want to go there. Yes, distance lends enchantment to the view.
Exploring space is not as easy as you might think. It is beyond your imagination. Scientists still make great contributions to exploring space and they also get good results. Space exploration is developing successfully. Scientists have made great progress with this project in only a few years’ time.
In the past fifty years, people have launched many detectors into the unknown universe and planets. However, most of them ended with failure. These detectors still helped the scientists and people to know more about this science. The first time they launched the detectors to Mars was in 1960s. From then on, two super countries, America and the Soviet Union, started a competition to explore Mars. They never stopped launching detectors to Mars. Even if two thirds of them failed. However, it didn’t stop us from exploring space.
Distance should not be an obstacle to exploring space. At the beginning of XX. NASA Launched two detectors to Mars, and both of them landed safty. They sent many useful information to Earth. It was really exciting news! Before that, a detector launched by Europe was lost in Universe. It was a shock to the scientific community, but they will never give up.
As a matter of fact, the purpose of launching so many detectors to space is to find a planet with life and the basic element – water.
The moon is far away from Earth, but it is the nearest star to Earth. People have been fascinated by the moon since ancient times until 1969 when astronauts from America landed on the moon. They found that the moon was just a satellite, without water, air, atmosphere and life, so people’s fantasies about moon were broken. The moon is a real “Wide-cold Palace”, it also has very bad weather, extremely cold at night and extremely hot during daytime. Nothing can subsist on the moon. When the astronauts landed on the moon, it was as if the distance went from 380 thousand kilometers to zero kilometers. All the beautiful fantasies and legends about moon were broken, so people now aim their eyes on Mars. They hope that one day the astronauts can step on Mars and realize our new dream.
Since we know the truth of moon, it is not so tempting to us. But poems about the moon can still give us some yearning.
Compare the beginnings of space travel with exploring space today. The exploration of space today is more useful. Many people are fond of Mars because among the nine planets in the solar system it is the most similar to Earth, so we call them “Brother Planets”. On Mars, there is a thin atmosphere lay and some oxygen. The detectors have found that there once exisited water. Due to the low gravity, the water all ran into space. The exploration of space is not only helping us know more about the unknown space, but also telling us a way to the new science and possibly a homeland. In other words, people may realize the dream of living on another planets.

Introduction
"Exploring Space," a comprehensive work that delves into the centuries - long journey of human beings pursuit of the cosmos, serves as a window opening up the mysterious and vast universe to readers. From the early observations of celestial bodies with the naked eye to the launch of advanced space probes and the realization of human landing on the moon, every page of this book is filled with the wisdom and efforts of countless scientists, engineers, and explorers. After reading this book, I was deeply shocked by the grandeur of space exploration and couldnt help but think about the profound scientific significance behind this great cause. This review will focus on analyzing the scientific value of space exploration elaborated in the book and discussing how it promotes the progress of human civilization.
The Promotion of Basic Scientific Research
One of the most striking points in "Exploring Space" is that space exploration has become a powerful driving force for the development of basic sciences such as astronomy, physics, and chemistry. Since ancient times, human beings have been full of curiosity about the stars and the universe. However, due to the limitations of Earths environment and observation tools, our understanding of the universe was once very limited. It was not until the advent of the space age that this situation was fundamentally changed.
The book mentions that the launch of the Hubble Space Telescope is a milestone in the history of astronomy. Before the Hubble Telescope was put into use, astronomers could only observe celestial bodies through ground - based telescopes, which were greatly affected by the Earths atmosphere. The atmosphere will cause the distortion of light, making the images of celestial bodies observed unclear, and also absorbing a large number of electromagnetic waves in the universe, which limits the scope and depth of observation. The Hubble Space Telescope, which operates in the low - Earth orbit outside the atmosphere, has avoided these interference factors. It has taken a large number of clear and precious images of celestial bodies, allowing astronomers to observe distant galaxies, nebulae, and black holes that were previously invisible. Through the data obtained by the Hubble Telescope, scientists have accurately measured the expansion rate of the universe, confirmed the existence of dark energy, and made important progress in understanding the origin and evolution of the universe. These achievements not only enrich our knowledge of the universe but also put forward new questions and challenges for the basic theory of physics, promoting the development of disciplines such as cosmology and particle physics.
In addition, space exploration has also promoted the development of chemistry and materials science. In the process of building space shuttles, space stations, and space probes, scientists need to develop a variety of new materials that can adapt to the harsh space environment. For example, the outer shell of a space shuttle needs to withstand extreme high temperatures when entering the atmosphere and extreme low temperatures in space. This requires materials with excellent high - temperature resistance, low - temperature resistance, and mechanical properties. In order to meet these needs, researchers have developed a series of advanced composite materials, such as carbon - fiber - reinforced composites and ceramic matrix composites. These materials not only play an important role in space exploration but also are widely used in aviation, automobile, and construction industries after being improved, promoting the technological progress of related industries. At the same time, the study of the chemical composition of celestial bodies in space, such as the detection of water and organic matter on Mars and comets, helps us understand the origin of life in the universe and provides a new perspective for the study of biochemistry.
The Driving Force for Technological Innovation
"Exploring Space" also vividly shows that space exploration is a "test field" for technological innovation, which has spawned a large number of cutting - edge technologies and promoted the rapid development of human societys science and technology. Many technologies that we are familiar with today were first developed for space exploration and then gradually applied to daily life.
The global positioning system (GPS) is a typical example. The book introduces that the original purpose of developing GPS was to provide accurate positioning and navigation services for spacecraft such as satellites and space shuttles in space. In order to achieve this goal, scientists have launched a large number of navigation satellites, built a global satellite navigation network, and developed high - precision positioning algorithms. With the continuous improvement and development of the GPS system, it has gradually entered peoples daily lives. Today, GPS is widely used in transportation, mapping, communication, and other fields. Drivers rely on GPS for navigation to avoid getting lost; surveying and mapping personnel use GPS to conduct high - precision land surveys; mobile phone users use GPS to share their location with friends and family. The popularity of GPS has not only improved peoples quality of life but also promoted the development of related industries such as the Internet of Things and intelligent transportation.
Another example is the development of medical technology. In the process of long - term space missions, astronauts will face a series of health problems, such as muscle atrophy, bone loss, and cardiovascular function decline, due to the weightless environment in space. In order to solve these problems, scientists have developed a variety of advanced medical monitoring equipment and rehabilitation technologies. For example, the portable physiological parameter monitoring device can real - time monitor astronauts heart rate, blood pressure, and other physiological indicators, and send the data back to the ground for doctors to analyze and evaluate. This technology has been applied to the field of medical care on the ground, enabling doctors to remotely monitor the health status of patients with chronic diseases such as hypertension and diabetes, and provide timely treatment and guidance. In addition, the research on the mechanism of muscle atrophy and bone loss in the weightless environment has also provided new ideas for the treatment of osteoporosis and other diseases on the ground.
The Expansion of Human Living Space
With the continuous growth of the global population and the increasingly serious problems of resource shortage and environmental pollution on the Earth, the search for a new living space for human beings has become an important issue facing the future development of human society. "Exploring Space" points out that space exploration is an important way to solve this problem, and it provides the possibility for human beings to expand their living space to other planets.
Mars is currently one of the most promising planets for human colonization. The book details the process of human exploration of Mars, from the early flyby missions of Mars probes to the later landing and roving missions. Through these missions, scientists have obtained a large number of data and samples of Mars, and have a deeper understanding of the geological structure, climate environment, and resource distribution of Mars. It has been found that there is a large amount of water ice under the surface of Mars, which is an important resource for human survival. In addition, Mars also has a certain atmosphere, although it is much thinner than the Earths atmosphere and mainly composed of carbon dioxide, but through technological transformation, it may be possible to create a livable environment for human beings. At present, many countries and private enterprises have launched Mars exploration programs and formulated plans for human landing on Mars and even the establishment of Mars bases. Although there are still many technical and practical difficulties to be solved, the exploration of Mars has taken an important step for human beings to expand their living space to the universe.
In addition to Mars, the moon is also an important target for human space exploration and development. The moon is close to the Earth, and its environment is relatively stable, which is conducive to the establishment of a space base. The book mentions that the moon has rich mineral resources, such as helium - 3, which is a clean and efficient nuclear fusion fuel. If helium - 3 on the moon can be mined and utilized on a large scale, it will effectively solve the energy crisis on the Earth. At the same time, the moon can also be used as a transit station for human exploration of deeper space, reducing the cost and difficulty of space missions.
Conclusion
After reading "Exploring Space," I have a deeper understanding of the scientific significance of space exploration. It is not only a great cause that satisfies human curiosity about the universe but also an important driving force for the progress of human civilization. Space exploration promotes the development of basic sciences, drives technological innovation, and provides the possibility for the expansion of human living space. Although the road of space exploration is full of difficulties and challenges, the achievements we have made so far have proved that this is a road worth persisting in. In the future, with the continuous progress of science and technology, human beings will surely make more brilliant achievements in space exploration and move towards a broader future in the universe.

Introduction
"Exploring Space" is not only a book about science and technology but also a work that contains profound humanistic connotations. It records not only the process of human beings exploration of the universe with scientific and technological means but also reflects the spiritual pursuit and value orientation of human beings in this great cause. When I read this book, I was not only attracted by the wonderful descriptions of the universe but also deeply moved by the humanistic stories behind space exploration. This review will explore the humanistic value of space exploration from the perspectives of the promotion of humans sense of unity, the inspiration of humans spiritual strength, and the inheritance of human culture, as elaborated in "Exploring Space."
The Promotion of Humans Sense of Unity
One of the most touching aspects of "Exploring Space" is that space exploration has broken the boundaries of countries, nations, and regions, and promoted the sense of unity and cooperation among human beings. In the face of the vast and mysterious universe, human beings are like a small community on the Earth. The challenges and difficulties in space exploration can only be overcome by the joint efforts of all human beings.
The International Space Station (ISS) project is a typical example of global cooperation in space exploration. The book introduces that the ISS is a large - scale space facility jointly built by 15 countries, including the United States, Russia, Europe, Japan, and Canada. The construction of the ISS started in 1998 and took more than ten years to complete. During this process, scientists and engineers from all countries worked closely together, sharing technology, experience, and resources. They overcame a series of technical difficulties, such as the docking of space modules, the supply of life support systems, and the maintenance of the space station. The ISS not only provides a platform for scientific experiments in space but also becomes a symbol of global cooperation and peace. Astronauts from different countries live and work together on the ISS, carrying out scientific research and experiments, and promoting the exchange and integration of different cultures. Through the ISS project, people have realized that in the face of the common challenges of human beings, such as the exploration of the universe and the protection of the Earths environment, national boundaries are insignificant. Only by uniting and cooperating can we create a better future for human beings.
In addition, the Apollo moon landing program is also a great event that promotes the sense of unity of human beings. In 1969, the United States successfully landed the first human being on the moon. When Neil Armstrong stepped on the moons surface and said, "Thats one small step for man, one giant leap for mankind," the whole world was shocked and excited. This sentence not only represents the great achievement of the United States in space exploration but also symbolizes the progress of human civilization. People from all over the world, regardless of their nationality, race, or religion, celebrated this great moment together. The Apollo moon landing program has let people see the potential and strength of human beings, and also let people realize that we are all members of the same human family, sharing the same Earth and the same future in the universe.
The Inspiration of Humans Spiritual Strength
"Exploring Space" also shows that space exploration is a great cause full of risks and challenges, and it has inspired the spiritual strength of human beings, such as courage, perseverance, and the pursuit of excellence. In the process of space exploration, countless astronauts, scientists, and engineers have made great sacrifices and efforts, and their stories have become a source of inspiration for people.
The story of Yuri Gagarin, the first human being to enter space, is deeply moving. In 1961, Gagarin took the Vostok 1 spacecraft to enter space, opening a new era of human spaceflight. At that time, the technology of spaceflight was still in its infancy, and there were great risks in the mission. No one knew whether Gagarin could successfully return to the Earth. However, Gagarin did not flinch. He faced the challenge bravely and completed the mission successfully. His courage and determination have inspired generations of people. The book describes Gagarins training process and the details of the mission, which makes us see the hard work and dedication behind his success. Gagarins story tells us that as long as we have the courage to face challenges and the determination to pursue our dreams, we can overcome all difficulties and achieve our goals.
Another example is the story of the astronauts of the Apollo 13 mission. In 1970, the Apollo 13 spacecraft suffered a serious malfunction during its flight to the moon, and the lives of the three astronauts were in danger. However, the astronauts did not give up. They worked closely with the ground control center, using the limited resources on the spacecraft to repair the malfunction and find a way to return to the Earth. After several days of hard work, they finally successfully returned to the Earth. This mission is known as the "successful failure" in the history of spaceflight. Although the mission did not achieve the goal of landing on the moon, it showed the strong will and wisdom of human beings in the face of danger. The story of the Apollo 13 mission has been adapted into a movie, which has inspired countless people to face the difficulties and challenges in life with a positive attitude.
In addition, the pursuit of excellence in space exploration has also inspired the progress of human society. In order to achieve the goal of space exploration, scientists and engineers are constantly pursuing higher, faster, and more accurate technical standards. They have made unremitting efforts to improve the performance of space vehicles, the accuracy of navigation systems, and the reliability of life support systems. This pursuit of excellence has not only promoted the development of space technology but also influenced other fields of human society. For example, in the field of manufacturing, the quality control standards and production processes of space products have been adopted by many enterprises, improving the quality and reliability of products. In the field of education, the spirit of space exploration has inspired students to pursue knowledge and innovation, and cultivate their sense of responsibility and mission.
The Inheritance of Human Culture
Space exploration is not only a process of exploring the unknown world but also a process of inheriting and developing human culture. "Exploring Space" points out that in the process of space exploration, human beings have carried their culture to the universe, and at the same time, they have also gained new insights and understanding of their own culture.
The launch of cultural relics and works of art into space is a way to inherit human culture. For example, the Voyager 1 spacecraft launched by the United States in 1977 carries a "golden record," which contains a variety of cultural symbols of human beings, such as music, images, and text. The music on the record includes classical music from different countries and regions, such as Beethovens "Fifth Symphony" and Chinese folk music "Jasmine Flower." The images include pictures of the Earths scenery, human beings daily life, and scientific and technological achievements. The text includes greetings in different languages. The purpose of carrying the "golden record" is to let possible extraterrestrial civilizations understand the culture and civilization of human beings. Although the Voyager 1 spacecraft has flown out of the solar system and is moving towards the depths of the universe, the "golden record" on it has become a symbol of human culture, carrying the hope and wish of human beings to communicate with the universe.
In addition, space exploration has also promoted the development of literature, art, and other fields. Since the advent of the space age, a large number of literary works, movies, and paintings with space exploration as the theme have emerged. These works not only describe the wonderful scenes of the universe and the process of space exploration but also reflect the thinking and exploration of human beings on their own existence and the future of civilization. For example, the science fiction movie "2001: A Space Odyssey" directed by Stanley Kubrick is a classic work about space exploration. The movie describes the process of human beings contact with extraterrestrial civilizations and the evolution of human civilization, which has a profound impact on the development of science fiction movies and even the way of thinking of human beings. The emergence of these works has enriched the content of human culture and promoted the spread and inheritance of the spirit of space exploration.
Conclusion
The humanistic value of space exploration is an important part of the significance of space exploration. As shown in "Exploring Space," space exploration promotes the sense of unity of human beings, inspires the spiritual strength of human beings, and inherits and develops human culture. These humanistic values not only play an important role in the process of space exploration but also have a far - reaching impact on the development of human society. In the future, with the continuous development of space exploration, we should pay more attention to the humanistic connotations behind it, and use the spirit of space exploration to promote the progress of human civilization and create a better future for human beings.
