5th MetMeSS is an national space science symposium, traditionally organized by the Physical Research Laboratory (PRL) and, for the first time, being hosted by the Indian Institute of Space Science and Technology (IIST). The event is being collaboratively conducted by the Department of Earth and Space Sciences and the Department of Physics, marking a major milestone in strengthening India's role in planetary science and space exploration. The symposium aims to foster collaboration among scientists, researchers, and students working in meteoritics, planetary geology, cosmochemistry, and astrobiology, thereby advancing our understanding of the Solar System's origin and evolution. It will serve as a premier platform to share the latest developments in the study of extraterrestrial materials, including meteorites, lunar, martian, and asteroid samples, through cutting-edge analytical techniques. 5th MetMeSS will be an in-person gathering, bringing together the multidisciplinary planetary science community and covering a wide spectrum of topics such as meteors and space weathering, extraterrestrial organics, planetary surface and subsurface processes, small bodies, astrochemistry, astrobiology, and terrestrial analogues.
