Abstract
Today, the near‐Earth space is facing a paradigm change as the number of
new spacecraft is literally skyrocketing. Increasing numbers of small
satellites threaten the sustainable use of space, as without removal,
space debris will eventually make certain critical orbits unusable. A
central factor affecting small spacecraft health and leading to debris
is the radiation environment, which is unpredictable due to an
incomplete understanding of the near‐Earth radiation environment itself
and its variability driven by the solar wind and outer magnetosphere.
This paper presents the FORESAIL‐1 nanosatellite mission, having two
scientific and one technological objectives. The first scientific
objective is to measure the energy and flux of energetic particle loss
to the atmosphere with a representative energy and pitch angle
resolution over a wide range of magnetic local times. To pave the way to
novel model‐in situ data comparisons, we also show preliminary results
on precipitating electron fluxes obtained with the new global
hybrid‐Vlasov simulation Vlasiator. The second scientific objective of
the FORESAIL‐1 mission is to measure energetic neutral atoms of solar
origin. The solar energetic neutral atom flux has the potential to
contribute importantly to the knowledge of solar eruption energy budget
estimations. The technological objective is to demonstrate a satellite
deorbiting technology, and for the first time, make an orbit maneuver
with a propellantless nanosatellite. FORESAIL‐1 will demonstrate the
potential for nanosatellites to make important scientific contributions
as well as promote the sustainable utilization of space by using a
cost‐efficient deorbiting technology.
