Astronomers For the first time the earth، The moon and solar collisions with Mars simultaneously Storm has been detected.
This is a development that the sun To better understand storms from and in the future Astronauts can help protect
The solar storm that erupted on October 28, 2021 was so widespread that energetic particles from the Sun fell on the surface of Mars and Earth, which are on the opposite side of the Sun and about 250 million kilometers away.
According to a new study published Wednesday in the journal Geographical Research Letters, this is the first time that solar activity has been measured simultaneously on the surface of Earth, the Moon and Mars.
Researchers examined solar activity detected by an international fleet of spacecraft.
The fleet includes NASA’s Curiosity Mars Rover, China’s Chang’e-Four Moon Lander and the European Space Agency’s ExoMars Trace Gas Orbiter (TGO).
Scientists say that solar activity was a normal phenomenon ‘on Earth’, during which energetic particles from the Sun passed through the Earth’s magnetic bubble, which surrounds the Earth and made the planet as it is. Protects from solar storms.
Since the Moon and Mars do not have their own magnetic fields, particles from the Sun can easily reach their surface and combine with their soil to cause secondary radiation.
According to scientists, understanding such solar phenomena is important because the Moon and Mars are the focus of future human exploration.
Radiation in excess of seven hundred milligrammes, the unit of radiation absorption, can cause radiation sickness in astronauts.
This results in the loss of bone marrow in the astronauts and symptoms such as inflammation and bleeding within the body.
Astronauts exposed to more than 10 Grays of radiation are unlikely to survive more than two weeks, scientists said.
In comparison, the amount of radiation in the lunar orbit resulting from solar activity in October 2021, as measured by NASA’s Lunar Reconnaissance Orbiter (LRO), was about 31 milligrammes.
Jing Guo, co-author of the study, said: ‘Evaluations of past events of solar particles reaching the surface of the Moon show that radiation on the Moon may exceed safe levels in an average event every five and a half years.
“If radiation protection is not provided, it is important to understand these events with respect to future manned missions to the lunar surface.”

The research also revealed important information about how Mars’ tenuous atmosphere provides protection against solar radiation.
Measurements by the Curiosity rovers at ExoMars TGO and I show that the October 2021 solar storm delivered 9 mg of radiation to Mars’ orbit, compared to the 0.3 mg of radiation found on the Red Planet’s surface. was 30 times more than
The new findings could add to knowledge for better design of protective space suits for astronauts.
TGO project scientist Colin Wilson said: ‘Cosmic radiation can pose a real threat to our research throughout the solar system. Measurements by robotic missions of radiation resulting from high-radiation events are critical to preparing for long-duration manned missions.
“Thanks to data from missions like ExoMars TGO, we can plan how we can best protect our human crew as researchers.”

**Interview with Dr. Jing Guo on Solar Storms and Their Implications for Space Exploration**
**Editor**: Thank you, Dr. Guo, for joining us today. Your recent study highlights a significant milestone in solar research—detecting solar activity affecting Earth, the Moon, and Mars simultaneously. Can you explain why this discovery is so important?
**Dr. Guo**: Thank you for having me. This discovery is crucial because it provides a comprehensive understanding of solar activity across different celestial bodies. By analyzing the impacts of solar storms on Earth, the Moon, and Mars, we can share insights that will enhance our preparedness for future human exploration, especially since Mars and the Moon lack protective magnetic fields.
**Editor**: You mentioned that the solar storm on October 28, 2021, was particularly widespread. What were the conditions during this event that allowed it to reach these distant locations?
**Dr. Guo**: The event was characterized by a significant release of energetic particles from the Sun, which traveled across a distance of about 250 million kilometers to affect both Earth and Mars simultaneously. Our research utilized data from various spacecraft, including NASA’s Curiosity Rover and China’s Chang’e-Four Lander, which allowed us to measure the effects of the storm in real-time on the surfaces of these bodies.
**Editor**: What are the potential risks for astronauts exposed to solar radiation during their missions to the Moon and Mars?
**Dr. Guo**: Radiation exposure poses serious health risks. Levels exceeding 700 milligrams can result in radiation sickness, leading to severe symptoms such as inflammation and internal bleeding, with high doses—over 10 Grays—being fatal within a fortnight. Understanding the radiation levels during solar events is vital for ensuring the safety of astronauts on future missions.
**Editor**: Your study notes that radiation levels on the Moon may exceed safe limits every five and a half years. What measures can be taken to protect astronauts from such radiation?
**Dr. Guo**: It’s essential to develop robust radiation shielding for habitats and spacesuits, as well as to establish effective monitoring systems for solar activity to predict and prepare for solar storms. Additionally, creating protocols for crew safety during high-radiation events will be critical for successful long-term missions.
**Editor**: Thank you, Dr. Guo, for sharing your insights. Your research is incredibly timely as we look to the future of human space travel.
**Dr. Guo**: Thank you for having me. It’s a critical time for space exploration, and understanding these solar phenomena will be key to our success on Mars and the Moon.
