There has been a renewed interest in the exploration of the Moon in recent years. Monitoring the radiation environment on and around the Moon is useful for advancing our understanding of galactic cosmic rays and solar energetic particles, identifying resources on the Moon, and improving the radiation safety of future astronauts. This talk will focus on the LunPAN mission and the Lunar HardPix detector, both being developed in collaboration with the IEAP CTU. LunPAN is a proposed spacecraft designed to orbit the Moon at low altitudes, measuring the spectra of charged particles from 0.1 GeV/n to 10 GeV/n and analyzing lunar albedo particles. The Lunar HardPix detector, intended for deployment on a lunar rover, aims to identify areas with higher concentrations of water in the lunar soil by measuring the flux of lunar albedo neutrons. Both missions would utilize Timepix3 or Timepix4 hybrid pixel detectors.
