Why has Mars become the key target geography for people to study at present?

The answer is related to human beings themselves. Scientists believe that there may be life and liquid water on Mars, so finding life and water has become a great dream for scientists all over the world. If there is life and water on Mars, it may be another planet suitable for human habitation, and it is also possible for human beings to emigrate to Mars and open up new living space. Therefore, since the 196s, The United States, the former Soviet Union, Europe and Japan have all started to explore Mars. Since November 5, 1964, human beings have launched more than 3 spaceships and Mars probes to Mars, but two-thirds of them ended in failure. However, scientific research has never ruled out the possibility of life on Mars. At present, the "Mars Global Surveyor" in the United States? Number and "Odyssey? Mars is still in orbit near Mars, sending back a lot of precious data and photos.

In the past 3 years, the spacecraft showed us that Mars is a barren land with rocky, cold and covered in a fuzzy pink sky. Scientists have found that Mars today once had an active volcanic period, a huge crater formed by meteor impact, and traces of instantaneous flood erosion.

Due to the application of new technologies, Mars probes are getting lighter, smaller and more sensitive. The twin Mars rovers, Courage and Opportunity, which are launched by the United States this time, cost 8 million dollars in total, and are the most sophisticated robots sent by human beings to another planet. It is revealed that they will be on the other side of Mars. "Could they have been lakes? Landing at the site, and there are almost no restrictions when traveling and carrying out scientific research activities. Experts from NASA claim that this Mars exploration program will become the "Apollo? The largest long-distance space scientific research activity since the moon landing.

According to the plan, after a long journey to Mars, the rovers Spirit and Opportunity will travel on this red planet with solar energy as the power for three to four months. During this period, they will continuously send back information about Martian rocks, soil and atmosphere to the ground and take a lot of pictures.

In this international competition to explore Mars, Russia has drawn up a landing plan for Mars. It is planned that around 215, the Russian Mars exploration team will fly to Mars in a manned spaceship, which will last for 44 days. It is reported that China is also carrying out related research on Mars exploration.
