Phobos-Grunt FREND: Fine Resolution Epithermal Neutrons Detector FREND is a neutron detector with a collimator and dosimeter module. Measurements are performed in a narrow field of view of about 10°, allowing to estimate the presence of water in the Martian surface with approx 40 km resolution. This is 10 times better than the resolution of currently exiting HEND/Odyssey map: Poly HEND/Odyssey data, ~400 km resolution 10B 400 km pixel 3He Gale Crater 40 km pixel Simulation of FREND/TGO data, ~40 km resolution Martian neutron energy ranges: Epithermal (3He counters): 0.4 eV – 500 keV Fast (Stylbene Scintillator): 0.5 – 10 MeV Spatial resolution: ~ 40 km at 400 km orbit Scint Preliminary design FREND Collimator Dosimeter module Silicon based semi-conductor detector Resolution: < 100 keV for 100 keV – 10 MeV range; < 350 keV for 10 MeV – 80 MeV range Measured values: Absorbed dose: 10-5 – 101 Gy Absorbed dose rate: 10-6 – 10-1 Gy/h Flux of particles: 1 – 1000 particles·cm2/s Time resolution of absorbed dose and flux: 1 min Time resolution of ionization losses spectr: 1 hr FREND is practically identical to LEND instrument onboard Lunar Reconnaissance Orbiter, which is orbiting the Moon since 2009 and proved it’s efficiency in both design and neutrons collimation concept that allows high resolution orbital mapping of neutron fluxes.

Phobos investigation Joint project proposal There is an ESA proposed project for Phobos sample return (PHOOTPRINT) with a launch in 2022 and sample return in 2025. Given high scientific value of Mars satellites exploration, existing Russian developments in a field of sample return from the surface of Phobos and ESA interest to such a project, it is suggested to study (can be done by existing working group) feasibility of a joint ESARoscosmos project on Phobos Exploration. 2020-2022 гг. – launch of a mission for landing on Phobos, in situ investigation of Phobos surface and sample return to the Earth. Mars-SR 2022-2024 The main scientific objective of Mars-Grunt project (which can be launched after 2022) is to provide science community with the samples from the Martian surface. The sample return from the Mars is being discussed by leading space agencies. Taking into account the technological complexity of such a mission and the high value of scientific output, it’s realization is more probable as a part of international cooperation. Another important outcome of this project will be a development of sample return technologies, which can be used during preparation of manned Mars exploration. Technological steps : Exomars Landing platform (2018) Moon sample return (2019-2020) Phobos sample return (2020-2022)
