HEXDC6 Cosmic rays.Artwork of high-energy particles radiation from prima successful heavy abstraction (cosmic rays) impacting molecules atoms successful Earth's atmosphere.These superior impacts origin secondary cascade of subatomic particles.Detection investigation of these particles,which see protons,neutrons,light nuclei,neutrinos,pions,and muons,can uncover root of cosmic rays.These sources whitethorn see gamma ray bursts (GRBs),active galactic nuclei,supernovae quasars.Such probe is carried retired atmospheric balloons,or precocious detectors built underground oregon underwater,to shield them from different radiation.

Navigation via cosmic ray muons could supplement GPS successful precocious latitudes, arsenic good arsenic moving underwater and underground.

The US Office of Naval Research (ONR) has awarded a declaration to UK institution Geoptic Infrastructure Investigations to show navigation successful the Arctic wherever GPS sum is poor owed to positioning of GPS satellites tally by the US military, which are mostly astatine little latitudes.

The firm’s Muometric Positioning System (muPS) uses muons made by cosmic rays instead of the vigor signals from satellites …
