NASA’s Mars Atmosphere and Volatile Evolution mission probe (MAVEN) has discovered “classes” and “cracks” in the charged part of Mars’ upper atmosphere (ionosis), according to the website of Nature and NASA’s website. The phenomenon is common on Earth and can lead to unexpected interruptions in radio communications, but so far the mechanism behind it has not been fully understood, and the discovery has made scientists realize that Mars is a great “laboratory” for studying the phenomenon.
Once upon a time, scientists believed that Mars was shrouded in a thick atmosphere that protected the Martian environment and allowed the red planet to appear and reproduce. Now, the scientific community has found that the Martian atmosphere is actually very thin, the surface of Mars is only a cold and barren. The mission of the US MAVEN probe is to investigate the mystery of the disappearance of the Martian atmosphere and to find out why the water and carbon dioxide it had had in its early years on Mars had disappeared. The probe went into orbit on Mars in 2013. It passes through the outer edge of the Martian atmosphere and uses eight scientific instruments to measure plasma in the atmosphere and space around Mars.
More recently, the MAVEN probe made an unexpected discovery, with measurements showing a sudden surge in plasma abundance to a peak as it flew over the Martian ionosphere. Joe Gribowski, a scientist at NASA’s Goddard Space Flight Center, says it’s almost the same peak he experienced before when he flew through Earth’s plasma layer by rocket. The MAVEN probe has now discovered the plasma layer, which can also appear on planets other than Earth.
More surprisingly, the results suggest that Mars could provide the conditions that Earth does not have, helping humans to explore accurately with existing probes.
People on Earth often encounter the phenomenon of radio stations suddenly without signal or platform, or plasma, which is a charged gas, and although it appears “on the top of everyone’s head” and can also be detected by radio, but because it has been “high above” and difficult to explore directly on Earth, so for us, The plasma layer is still very mysterious. Today, it is the natural “laboratory” to study this highly destructive phenomenon.
