1. Launch a manned spacecraft to Mars
Launching a manned spacecraft to the red planet can be said to be mankind’s greatest adventure in the 21st century. In the future, if this feat can be successfully achieved, it can be said to have completed the dream of mankind for centuries. More importantly, successfully landing on Mars will greatly promote the development of other aerospace projects around the world.
2. Achieve communication with aliens
How to find aliens and communicate with them always makes people feel like they don’t know where to start. So far, humans have made various efforts. For example, the University of California, Berkeley, has established a research project called “Search for Extraterrestrial Intelligence” (SETI).
In 1999, SETI scientists launched the SETI project and called on “computers around the world to unite” to search for aliens. At present, more than 5 million computers around the world have participated in this huge project. Each participant can download and run the SETI screen saver to allow his or her computer to participate in detecting signals from other planets. These The signal came from Arecibo, the world’s largest radio telescope in Puerto Rico.
In addition, SETI project scientists are also building a huge antenna array to receive “alien” radio signals. American scientists say that by 2028, the SETI program will complete “monitoring” of 1 million planets. “Searching for aliens” is regarded as the “least reliable” adventure, but it holds the greatest expectations of mankind. If communication with aliens is truly realized one day, then the human world will probably undergo unprecedented changes.
3. Humans land on the South Pole of the Moon
Although many places on the moon are waiting for human exploration, the south pole of the moon is the place that scientists most yearn for. The National Aeronautics and Space Administration (NASA) announced that the Centaur rocket and the LCROSS satellite have successively impacted the Cabbs Crater near the south pole of the moon. The dust kicked up by the Centaur rocket after impacting the moon is partly composed of vapor and dust, and the other part is composed of mass. Heavier material composition. Preliminary analysis results show that there are traces of water in the above two parts of smoke.
NASA has previously stated that if it can find water sources on the moon, it can start building a permanent base on the moon in 2020 as a springboard for the next step of exploring Mars. Currently, NASA has plans to send humans to the moon again before 2020.
4. Dive into the Mariana Trench
Adventurers have successfully conquered the world’s highest peak, Mount Everest, but so far they have not been able to conquer the world’s deepest trench, the Mariana Trench. The Mariana Trench is 11,034 meters below sea level and is located on the bottom of the Pacific Ocean northeast of the Philippines and near the Mariana Islands. Even if Mount Everest, the world’s highest peak, sinks here, its summit cannot emerge from the water.
The only people in history to have explored the Mariana Trench were Swedish engineer Jacques Piccard and U.S. Navy Lieutenant Don Wolson. The two took the “Trieste” deep-sea submersible and successfully dived to the 10,911-meter seabed, where they stayed for 20 minutes. In fact, human beings are no less curious about the deep sea world than their desire to conquer mountains. The deep sea is a high-pressure, dark and cold world. What kind of creatures can survive in this environment has always been a mystery that humans are eager to find. If we successfully explore the most mysterious place on the seafloor, the Mariana Trench, it will undoubtedly help mankind answer the above questions.
5. Head towards the center of the earth
In fact, as humans advance further and further in space exploration, they don’t know much about the earth where they live as they do about the surface of the moon. David Stevenson, an American professor of planetary science, once exclaimed: “Humanity’s exploration of the universe has now reached a distance of 6 billion kilometers, but its understanding of the earth itself is only 10 kilometers!”
In fact, it is far more important for humans to understand their home earth more thoroughly than to explore the universe, because successfully obtaining geocentric information can help humans better predict natural disasters such as earthquakes and tsunamis.
