The Fine-Resolution Epithermal Neutron Detector (FREND) is a neutron detector that is part of the instrument payload on board the Trace Gas Orbiter (TGO), launched to Mars in March 2016. This instrument is currently mapping hydrogen levels to a maximum depth of 1 m (3 ft 3 in) beneath the Martian surface, … See more FREND can provide information while orbiting Mars on the presence of hydrogen, in the form of water or hydrated minerals in the top 1 m (3 ft 3 in) of the Martian surface. Locations where hydrogen is found … See more • Astrobiology • Life on Mars • Water on Mars See more The main science objective of the instrument is to carry out high spatial resolution mapping of epithermal and fast neutron fluxes from … See more Cosmic rays are sufficiently energetic to break apart atoms in the top one or two metres of Mars' surface, releasing high-energy neutrons, which can be measured by FREND instrument. The distribution of neutron velocities measured reveals the hydrogen content, … See more WebPhysical value: Parameters measured: Detectors: Thermal neutron flux: 16-channel counts spectrum in 3 He counter, emerging from neutrons with energy less that 0.4 eV with temporal resolution from 1 s: STN1 — STN3 on the basis of 3 He counters with the pressure of 20 atm and the volume of ~100 sm 3 (produced by LND inc, USA): … WebDownload Citation Fine Resolution Epithermal Neutron Detector (FREND) for Mapping Martian Water from ESA's TGO The Fine Resolution Epithermal Neutron Detector (FREND) for ESA's TGO is described. is mint toxic
