Abstract The Electric Solar Wind Sail (E-sail) is an innovative propellantless propulsion
system conceived by Pekka Janhunen in 2004 for use in interplanetary space. An E-sail …

CubeSats are a class of miniaturized satellites that have become increasingly popular in
academia and among hobbyists due to their short development time and low fabrication …

The design, integration, testing and launch of the first Finnish satellite Aalto-1 is briefly
presented in this paper. Aalto-1, a three-unit CubeSat, launched into Sun-synchronous polar …

Earth's radiation belts are extremely important for space weather because they can store
and accelerate particles to relativistic energies, which can have a potential impact on …

The lower-thermosphere–ionosphere (LTI) system consists of the upper atmosphere and the
lower part of the ionosphere and as such comprises a complex system coupled to both the …

This paper presents two technology experiments–the plasma brake for deorbiting and the
electric solar wind sail for interplanetary propulsion–on board the ESTCube-2 and …

Nanosatellites have established their importance in low-Earth orbit (LEO), and it is common
for student teams to build them for educational and technology demonstration purposes. The …

The growing amount of space debris in geocentricorbit poses a significant threat to the future
of space operations. To mitigate this problem, current international guidelines state that a …
