About

Y Charara’s research centers on space radiation physics and instrumentation, with a particular focus on improving the accuracy of radiation detectors for lunar and deep-space missions. Their most notable contribution is the refinement of linear energy transfer (LET) estimates for the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO), launched in 2009. By leveraging the HETC-HEDS simulation code, Charara enhanced the instrument’s ability to characterize the radiation environment encountered by astronauts and electronics on the Moon. This work, published in 2011 and cited 3 times, directly supports LRO’s broader objectives—identifying safe landing sites and assessing potential resources—by providing critical data on radiation hazards. Though their citation count is modest, Charara’s contributions are foundational to space radiation risk assessment, an essential field for future crewed lunar missions and beyond. Their technical improvements to CRaTER’s LET calculations have helped ensure that the instrument delivers reliable measurements, aiding NASA’s long-term goals of sustainable lunar exploration.
