NASA to launch radiation protection vest on Orion EM-1 mission

StemRad, a developer of revolutionary technology that shields first responders, astronauts and soldiers from harmful radiation exposure, has announced that NASA and the Israel Space Agency have signed an agreement for the launch of StemRad´s AstroRad radiation protection vest aboard NASA´s EM-1 mission around the moon, the last test flight before the space agency begins deep space manned missions, the company said.

The deep space missions are the first since the Apollo missions.

The trial, called “Matroshka AstroRad Radiation Experiment”, or MARE in short, is the first time that the impact of radiation exposure on humans is being measured in deep space. The test will be comprised of two Matroshka test dummies – one bare and one wearing AstroRad. The Matroshkas, containing thousands of radiation detectors, will be supplied by the German Aerospace Center (DLR).

While EM-1 will not likely encounter a solar storm, the mission will pass through the Van Allen radiation belt – a zone of energetic charged particles that emanate from solar winds – providing an opportunity to test AstroRad in conditions similar to those found during a solar storm. When passing through the belt, the radiation sensors in the dummies will be on and will record readings during the passage. Should the trial be successful, AstroRad will be used on the upcoming planned manned missions to deep space.

StemRad is an Israeli-American company headquartered in Tel Aviv, Israel, that develops, manufactures and sells personal protective equipment (PPE) for ionizing radiation. It is the world´s only company producing PPE intended to protect users from high energy ionizing radiation and the first to employ selective shielding in its products. For more information, visit
