Is the slope stripe on Mars frost?
scifi.com, May 30 (wangziyu) in the 1970s, the Viking orbiter first observed dark landslides called slope stripes on Mars. For a long time, scientists have been speculating about its specific cause. It was not until recently that NASA scientists confirmed that it was a frost formed by carbon dioxide at low temperatures. The Odyssey spacecraft provided key images and data to determine this study. Odyssey is the Mars exploration satellite launched by NASA in 2001 and the longest running Mars exploration facility at present. After its successful launch, Odyssey has…
Scientists confirm the cause of the aurora on Mars
People can see brilliant auroras at the north and south poles of the earth, but not only the earth has auroras, but also other planets in the solar system (except mercury), and even some satellites or comets also see atmospheric glow. They are usually different from the earth’s aurora. Some of them occur in invisible bands such as ultraviolet light. Scientists also found Aurora at night in the southern hemisphere of Mars, but it is difficult to explain the reason, because Mars is famous for its lack of global magnetic…
Fascinating photos of the Grand Canyon of Mars released by the European Space Agency
The European Space Agency has taken amazing images of the Martian Grand Canyon, one of many unexplored areas on earth For decades, people have wondered whether Mars could become a livable planet for humans in the distant future, especially after space agencies detected water on the red planet. Although it is not clear whether Mars is a place where we can live, it has one similarity to the earth &mdash— Grand Canyon The European Space Agency (ESA) recently released photos of Mars’s own Grand Canyon, which are sure to surprise…
Zircon hypersonic missile, which is about to officially enter service, is known as the strongest “aircraft carrier killer”
For a long time, various countries have launched various killer maces to deal with the super large equipment such as aircraft carrier, including not only torpedo, but also missile, which are defined as being able to handle the aircraft carrier easily. However, there is a very realistic situation that must be considered: once the torpedo or missile is difficult to break through the joint protection of the aircraft carrier combat strike group or the attack distance exceeds its maximum limit, these so-called “ Carrier killer ” Can it live up…

Devil’s Eye Located in the northwest sky, there is a colorful devil’s eye, which is a geothermal hot spring gushing for thousands of years &mdash— Aiken spring. Water Yadan The only water Yadan landform group in the world is formed by the…
Is Musk’s idea of colonizing Mars wrong? Will Mars be destroyed earlier than the earth?
Besides the moon, Mars should be the most frequently explored celestial body. But today, some scientists predict that Mars may not be suitable for human habitation at all, because Mars will experience a great catastrophe, and Musk’s idea of Mars colonization cannot be realized at all. What’s the situation? According to the data, Phobos, a satellite of Mars, may be the key to the Mars catastrophe, because it may eventually hit Mars. Imagine that humans have turned Mars into a colonial paradise. Suddenly, a Phobos on the moon began to…
Scientists reveal the cause of the formation of Mars aurora for the first time
Science fiction network, May 20 (Liu Yazhu) as we all know, laser is a colorful plasma phenomenon. The reason for the generation of aurora is that after the solar wind enters the earth’s magnetic field, hydrogen ions react with the air in the atmosphere, so aurora are generated in the high-altitude areas near the earth’s North and south poles. Aurora is regarded as one of the most beautiful wonders in nature. It is generally banded, arc-shaped, curtain-shaped and radial. There is no fixed color, of which blue, green, white and…
The mysterious black stripes of Mars are related to invisible frost or dust avalanches
Science fiction network, May 18 (Qin Yingying) scientists may be able to explain why the frost on Mars cannot be seen by the naked eye and why dust avalanches appear on some slopes by analyzing the data of NASA Mars Odyssey orbiter. When scientists analyze photos of Mars, they found that when they observe the surface with visible light, they can see the ghostly blue and white morning frost illuminated by the rising sun. However, when the camera was used more widely in orbit, including the ice layer, it did…
The Mars rover perseverance crossed a sea of sand! Driving only 100 meters in 3 days, preparing for climbing
In the Martian world, which is about 142 million kilometers away from us, three rovers are carrying out different exploration missions in three different regions, but their purpose is the same: to understand Mars and find extraterrestrial life. The three rovers are American perseverance, American curiosity and China zhurong Among them, the fastest is the Mars rover perseverance, which has traveled 11.47 kilometers in the past 439 Mars days. You know, zhurong has only traveled 1.92 kilometers in the past 347 Mars days, and curiosity has traveled 27.88 kilometers in…
