A Promising Experiment with a Gamma Ray Spectrometer Onboard a Mobile Spacecraft to Study the Elemental Composition of the Moon, Mars, and Other Celestial Bodies without an Atmosphere or with a Thin Atmosphere.

A new concept of a space experiment with a γ-ray spectrometer onboard a mobile spacecraft has been proposed for studying the elemental composition of the Moon, Mars, and other celestial bodies without an atmosphere or with a thin atmosphere using the method of tagged charged particles of galactic cosmic rays. This technique makes it possible to eliminate almost fully the background of γ-radiation from the spacecraft with the instrument installed onboard and significantly increase the spatial resolution for studying the elemental composition of matter along the mobile spacecraft trajectory.
