English: In preparation for the Artemis I flight test, teams at NASA’s Kennedy Space Center in Florida prepare the Matroshka AstroRad Radiation Experiment (MARE) investigation on Aug. 5, 2022. MARE will fly on Artemis I and features two manikins, called phantoms – Helga and Zohar – equipped with radiation detectors to determine the radiation risk on its way to the Moon. The phantoms will be seated as passengers in the Orion crew module, with Zohar also wearing the experimental AstroRad radiation protection vest. The MARE experiment is part of an agreement between NASA, the Israel Space Agency, and the German Aerospace Center. Artemis I will provide a foundation for human deep space exploration and demonstrate NASA’s capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the Space Launch System rocket and Orion spacecraft’s integrated systems before crewed missions. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration.
