Tianwen-1 captured high-definition images of Mars. What are the characteristics of the Martian landscape?

Our country’s first Mars exploration is considered to be the Tianwen-1 Mars probe. After nearly half a year of flight, the Tianwen-1 probe successfully entered an orbit around Mars, with a flight mileage of nearly 500 million. kilometer. Previously, Tianwen-1 took the first photo of Mars when it was about 2.2 million kilometers away from Mars.

1. Tianwen-1 sent back high-definition images of Mars

NASA’s Perseverance rover has previously sent back a large number of photos of Mars, and many friends said that Tianwen-1 has also arrived Mars, why haven’t you sent back photos of Mars yet? Our Tianwen-1 may have taken a large number of photos of Mars, but they have not yet been released. It is not because our Tianwen-1 probe is not as capable as Perseverance in taking photos. This year, the National Space Administration released three photos of Mars from the Tianwen-1 shooting site. These high-definition photos include two full-color images and one color image. As we mentioned earlier, some netizens are hotly discussing why the first Mars photo taken by Tianwen-1 is not in color. Is it because of poor camera technology? Now the color photos returned by the Tianwen-1 probe have explained to us that Tianwen-1 Not only can it take black and white photos, but it can also take color photos.

2. What will be the challenge? 7 Minutes of Terror?

Although the Tianwen-1 probe is our country’s first Mars exploration mission, the function of Tianwen-1 is very powerful. It will complete the three major steps of orbiting Mars, landing on Mars, and patrolling Mars at once. Now the Tianwen-1 probe has entered the orbit around Mars and completed the first of three major steps. Next, the Tianwen-1 probe will continue to complete the second and third steps, which is expected to be completed in May. Choose an opportunity to land on Mars and send the rover to the surface of Mars. When the probe is preparing to enter the Martian atmosphere for landing, it needs to drop its speed from nearly 20,000 kilometers per hour to 0 relative to Mars. This process requires the cooperation of the probe's parachute, reverse thrust engine and other equipment and lasts about 7 minute. Because landing on Mars is the most difficult level of exploring Mars and full of challenges, it is also called the "7 Minutes of Terror". ?

3. The first batch of immigrants to Mars will hold "one-way tickets"?

We humans are now frequently exploring Mars. In addition to hoping to find Martian life on Mars, we also have a very important purpose, which is to study the habitability of Mars. Many scientists believe that Mars may become our "second home" in the solar system, that is, we humans may immigrate to Mars in the future. These probes will help us better understand Mars and its habitability. However, the initial immigration to Mars may not be a wonderful thing. After all, Mars is not suitable for direct human habitation. The report mentioned that the first batch of Mars immigrants may never return. These Mars immigrants passed away comfortably on Mars after spending a long life of work and leisure. Because returning to Earth from Mars is not an easy task.
