​​A”fire” was found on the surface of Mars? Perseverance rover has rockets installed, launch countdown

Although there are countless planets deep in the universe, our current human technology is limited, and we can’t explore those unusually distant alien planets yet. However, there are some relatively close celestial bodies around us, such as the moon and Mars. , These planets. In the past few decades, our exploration of Mars has been relatively extensive. There have been multiple probes flying around Mars, and even some probes have reached the surface of Mars. Although we have not yet found life on Mars, some photos sent back by the probe have caused many people to speculate that it may be a sign of life on Mars.

Mars”A cloud of fire” was found on the surface

In many photos of Mars, we can see various scenes on the surface of Mars, and may even see some strange phenomena. One of the photos of Mars published by NASA seems to have an obvious small bright spot, like a”fire”. What does it mean if a fire really appears on the deserted surface of Mars? One possibility is that”fire” occurs naturally, just as wildfires naturally occur in the Arctic region of our earth in summer; another possibility is that Mars”life” fires on the surface of Mars. Of course, these are just speculations. NASA scientists said that this photo was indeed taken on Mars, and this group of”fire” is not really”fire”. It may be that some high-energy particles from the universe entered Mars. After the effect. If this is really the case, it may mean that this phenomenon is just a normal natural phenomenon, not a strange thing.

2020 The Mars launch window is coming soon

It is now July 2020, which also means that the Mars rover, which is about to launch this year, has also begun to count down and is about to usher in the launch moment. At present, a number of Mars probes are ready to launch, waiting for the opportunity to launch at the right time, and start the journey to”fire.” NASA’s Fortitude probe is the one that will go to Mars this year. Although the launch time was adjusted some time ago, the Fortitude probe has now been “tied” to the rocket. That is to say, if there is no accident, it is estimated that it will be soon. Will launch into the air.

According to NASA’s scientific report, the Fortitude Mars rover has been Install to the top of Atlas V. Although the launch mission of the Persevere probe was delayed several times earlier, and the launch time was delayed, but now the probe is installed on the rocket, it also means that the Persevere probe should not miss this Mars launch window. According to the current plan, the Perseverance probe is expected to be launched from July 30, 2020 to August 15, 2020. Although the launch time may fluctuate for up to ten days, NASA said that no matter what day it is launched between July 30, 2020 and August 15, 2020, the Fortitude probe will land on Mars on February 18, 2021. On the surface of the Jezero crater.

The reason for the perseverance chose to land in this crater , Mainly because there may have been microorganisms in this crater. According to NASA data, this crater is located on the western edge of Isidis Planitia, a huge basin north of Mars’ equator. The width of the crater is about 45 kilometers. According to previous research, this crater was supposed to be a lake about 3 billion to 4 billion years ago, and flowing liquid water has flowed into this crater. On our planet, there are countless species of living creatures in lakes, and in the former lakes of Mars, there may have been life.

perseverance The No.1 probe is preparing for a round trip to Mars.

Because the Fortitude probe has not yet stepped on the surface of Mars, whether microorganisms can be found in the crater is temporarily unknown. NASA pointed out that the mission of the Fortitude probe is not only to find life on Mars, but also to prepare for the trip to and from Mars. According to our plan, launching unmanned probes is not our ultimate goal. We humans also want to be able to send astronauts to the surface of Mars. However, the spacecraft that manned to Mars needs to consider a question, that is, how to take astronauts Return to Earth safely. Because of this technical difficulty, we have not yet launched a manned landing project on Mars.

According to the plan, if the Fortitude probe successfully landed on Mars The surface will be the world’s first sampling and collection system brought to Mars by Mars Rover, which will collect rocks and sediments on the surface of Mars In preparation for sampling Mars back to Earth in the future. Due to the limited equipment of the probe, there is very little research that the probe can carry out. If we can bring Mars samples back to Earth, we can carry out more complicated analysis of these samples, and may find the potential life of Mars. .
