"Unveiling the Secrets of Solar Storms: A Photographic Journey"

On April 17, 2021, a widespread solar storm launched high-speed protons and electrons, known as solar energetic particles (SEPs), towards several spacecraft across the inner solar system, including those orbiting Mars. The diverse perspectives from these spacecraft revealed that different types of SEPs can be propelled into space by different solar phenomena and in different directions, posing potential risks to technology and human health. Scientists are eager to understand the origins and acceleration of these particles to improve protection measures. The event also highlighted the importance of multiple spacecraft in studying widespread solar phenomena, offering deeper scientific insight and a more complete picture of space events.

"Unveiling the Spectacular Solar Storm: Rare Images Capture Giant Plasma Eruption"

On April 17, 2021, a widespread solar storm hurled high-speed protons and electrons at velocities nearing the speed of light, striking several spacecraft across the inner solar system. This event, observed by spacecraft at five different locations, revealed that different types of potentially dangerous solar energetic particles (SEPs) can be blasted into space by different solar phenomena and in different directions. Scientists are eager to understand the origins and acceleration of these particles to better protect technology and humans in space. The event also demonstrated the importance of multiple spacecraft perspectives in untangling the complexity of solar events, paving the way for future NASA heliophysics missions to study widespread phenomena and the acceleration of particles into the solar system.

Solar Energetic Particle Event Detected on Earth, Moon, and Mars

A recent study has highlighted the risks of space radiation to lunar and Martian exploration, focusing on a Solar Energetic Particle (SEP) event detected on the surfaces of Earth, the Moon, and Mars. The research emphasizes the varying levels of natural protection against radiation on these celestial bodies and underscores the need for effective shielding to ensure astronaut safety in future space missions. Earth's magnetic field and atmosphere provide some protection, but the Moon and Mars lack similar shielding. Without adequate shielding, future lunar missions could face radiation risks during approximately one out of every five SEP events, while extreme SEP events during the journey to Mars or in Martian orbit pose a significant radiation risk for deep space missions.

Solar Eruption on Far Side of Sun Sends Shockwave to Earth

A powerful coronal mass ejection (CME) erupted from the far side of the sun on March 12, 2023, and impacted Earth. The CME was detected by NASA's Moon to Mars Space Weather Office and was classified as a rare type CME due to its unusually fast speed of 2,127 kilometers per second. The CME is likely to have hit NASA's Parker Solar Probe head-on, and solar energetic particles were detected by spacecraft orbiting Earth. Researchers are still analyzing the event to learn more about its far-reaching effects.
