Scientific and technical goals of the
ExoMars project
Completion of previously planned scientific missions:
Investigation of the Mars structure and climate at the surface (Mars-96 
Mars-Net).
Atmosphere investigation, search for methane, climate monitoring from the
orbit (Phobos-Grunt).
New scientific goals:
Subsurface water mapping with high resolution.
Exploration of Mars habitability.
Volcanism (search for volcanic gases).
Development of a joint (ESA-Roscosmos) ground segment for
interplanetary missions management.
Integration of Russian and European experience in technology
development for interplanetary missions and in quality control.
Preparation for the next steps in Mars exploration:
Landing sites investigation, subsurface water.
Dosimetry. Monitoring of radiation situation.

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:

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)
