"Zhurong" successfully landed on Mars! Revealing the secrets of human exploration of Mars

Right now, when it comes to the hot events that our people are most concerned about, the news that the "Zhurong" Mars rover successfully landed on Mars is definitely on the list. So, how much do you really know about the secrets of human exploration of Mars? Let’s take a look!

Exploring Mars

The history of human observation of Mars has a long history. As early as 1960, the Soviet Union tried to launch a probe to Mars for the first time, but it ended in failure. From that time to now, humans have launched 44 Mars missions, of which only 18 were successful, which shows how difficult it is to successfully achieve Mars exploration. And this time our successful landing also marks a further step in our country's space exploration.

Mars is not suitable for human survival

Because its orbit is very similar to that of the Earth, Mars has always been regarded as the first choice for interstellar immigrants by humans. But in fact, Mars is not suitable for human habitation. Although its surface looks red, its average temperature is more than minus 60 degrees. Not only that, the atmosphere of Mars is very thin, with a density of only 1% that of Earth, and is mainly composed of carbon dioxide and nitrogen. On the one hand, too low air pressure cannot withstand dangers such as radiation from space, and if humans take off their spacesuits on Mars, the pressure inside the body will be greater than the external atmospheric pressure, causing blood vessels throughout the body to expand and rupture, and the person will die before they can suffocate.

How is it? Does this kind of cold knowledge about Mars shock you? In fact, there are far more secrets about Mars. For example, although a day on Mars is only 40 minutes longer than a day on Earth, a Martian year is equivalent to 687 Earth days.
