Volatile elements such as hydrogen, carbon, and nitrogen were essential for the emergence of life on Earth. However, the origin of these elements accreted by planetary bodies of the inner solar system as well as their behavior, distribution, and inventory in deep planetary reservoirs remain controversial. Recent analytical developments in noble gas mass spectrometry and secondary ion mass spectrometry have allowed me to accurately determine the abundance and isotopic composition of nitrogen trapped in terrestrial volcanic rocks, meteorites (chondrites, achondrites, iron meteorites), samples brought back to Earth by space missions as well as in synthetic samples. In parallel, based on measurements of noble gases in meteorites and lunar rocks...
