What new discoveries may scientists have made in recent years in the study of Mars?

Dear, hello, I am glad to answer for you In recent years, scientists have discovered that Mars is mainly the ground of Mars, and there are some traces of water erosion on the surface, and at the same time, the probe on Mars has also found some mineral structures that can be formed with the participation of water, mainly these two. I hope you find the answer helpful.

According to reports, NASA has begun investing in research on an unbelievable but more feasible solution. It is reported that this plan was conceived by Rigel Voida, an engineering student at the University of Arizona in Tucson, USA. According to the idea, astronauts will place 300 balloons made of reflective materials, each up to 150 meters in diameter, in Martian orbit, and they will be suspended next to each other to form a "super-mirror" with a length and width.

The surface of Mars is notoriously cold, usually between -140 and -60, but when this "super mirror" is in place, it can reflect sunlight into an area of about 1 square kilometer on the surface of Mars and raise the temperature in that area to 20. Three benefits of space mirrors Wojda pointed out that once the temperature reaches 20, it will bring three major benefits to the Mars expedition. First, astronauts who land on Mars will no longer wear heavy, insulated spacesuits, or build a purpose-built Martian workstation at great expense, which will make life on Mars "as warm as spring."

Second, the sunlight reflected to the surface of Mars can also recharge the solar panels, giving astronauts a constant supply of "free" electricity. Third, the increase in temperature will also melt the ice on the surface of Mars into precious liquid water, which will not only be drinkable by astronauts, but also used as a feedstock for the production of rocket fuel, giving spacecraft enough power to return to Earth. Building a Second Earth What's even more desirable is that Wojda said that his ultimate goal is to set up one of these "super mirrors" every 90 kilometers in Martian orbit to circle the entire Mars.

The sun's light and heat melt the ice sheet at Mars' south pole and create greenhouse gases on the surface of Mars, or saturate it with ammonia and methane.

Meteorites of greenhouse gases fell to the surface of Mars in large numbers. In this way, the average temperature of Mars rises to freezing, which helps plants to grow, and the plants can reproduce and grow enough to produce enough oxygen. Hundreds or even thousands of years from now, when sunlight will reach every corner of icy Mars, giving Mars an atmosphere suitable for human breathing, and then Mars will become the ideal "second Earth" for mankind.

Plagued by two major problems However, some experts also warn that setting up a "super mirror" in Martian orbit will face huge challenges. First of all, it was extremely difficult to transport 300 balloons with a diameter of up to 150 meters into space, not to mention assembling them into a huge mirror with a length of kilometers and a width of one kilometer. Second, another potential problem is that, if not properly designed, the "super-mirror" could potentially reflect harmful high-frequency radiation, such as gamma rays, onto the surface of Mars, causing fatal injuries to Martian astronauts.
