Exploring Radiation Beyond Earth's Shield: Insights from Artemis I Mission

Scientists used mannequins Helga and Zohar on NASA's Artemis I mission to gather data on radiation exposure beyond Earth's magnetic field. The findings will help protect astronauts on future missions to the moon and Mars. Various sensors provided valuable insights, revealing differences in radiation shielding within the spacecraft.

NASA's Artemis I mission has yielded groundbreaking data on radiation exposure outside Earth's magnetic field using mannequins Helga and Zohar. The mission, which lasted 25 days, aimed to glean insights into protecting astronauts during deep space journeys, such as potential missions to Mars.

Researchers equipped the mannequins with sensors to measure radiation levels within the Orion spacecraft. Key instruments included NASA's HERA and the European Space Agency's EAD sensors. Findings indicated significant variations in shielding within the spacecraft, crucial for designing safer long-term space missions.

Lead author Thomas Berger from the Institute of Aerospace Medicine noted that high-risk radiation sources include galactic cosmic rays and solar flares. The data showed Zohar's vest provided enhanced protection. This research is essential for future lunar and Martian expeditions, ensuring astronauts' safety during protracted spaceflights.
