Solar Phenomenon Makes History: Simultaneous Explosion Felt on Earth, Moon, and Mars

A massive eruption of plasma and magnetically charged particles came from the sun on October 28, 2021. The huge solar eruption bombarded Earth, the moon, and Mars with radiation. Additionally, equipment on all three bodies measured the same event practically simultaneously for the first time.

The ExoMars Trace Gas Orbiter (TGO) of the European Space Agency and the Curiosity Rover of NASA both detected the inflow of charged particles on Mars. The Lunar Reconnaissance Orbiter (LRO) of NASA and the Chinese National Space Administration’s Chang’e-4 both detected these particles on the moon. 

The Eu:CROPIS satellite from the German Aerospace Center also picked up radiation coming from low Earth orbit. Geophysical Research Letters published a paper on the results of this solar trifecta on August 8.

Future space travel, such as plans to send personnel to Mars and to create a scientific station on the moon, will be greatly aided by an understanding of these phenomena, known as coronal mass ejections (CMEs).

Cosmic Shockwave

On Earth, the magnetic field protects humanity from the most harmful solar outbursts. However, the absence of this shielding magnetosphere on the moon and Mars implies that far more radiation reaches their surfaces.

Astronauts may experience adverse effects from all that radiation. According to 2014 research published in the journal Life, exposure to high quantities of radiation can cause skin irritation, nausea, blood abnormalities, decreased immunity, and even cancer. 

It can result in burns and brain deterioration in severe situations. 

One gray, or one unit of radiation, is equal to approximately 700 milligrams, which is considered a harmful dosage. Fortunately, the CME on October 28 was much weaker than that, measuring only around 31 millimeters; nevertheless, as the sun gets closer to the top of its 11-year solar activity cycle, which might start as early as the end of 2023, CMEs grow more frequent and more strong.

The latest research discovered that by the time the radiation from the event reached the surface of our planet, Earth’s magnetosphere and atmosphere had rendered it insignificant. Due to the buffering effects of its atmosphere, Mars’ surface received a dosage that was around one-third of the initial amount.
