M. R. Mughal, J. Praks, R. Vainio +17
The in-orbit results and lessons learned of the first Finnish satellite Aalto-1 are briefly presented in this paper. Aalto-1, a three-unit CubeSat which was launched in June 2017,…
FORESAIL-1 cubesat mission to measure radiation belt losses and demonstrate de-orbiting
FORESAIL collaboration, M. Palmroth, J. Praks +57
Today, the near-Earth space is facing a paradigm change as the number of new spacecraft is literally sky-rocketing. Increasing numbers of small satellites threaten the sustainable…
Steam balloon concept for lifting rockets to launch altitude
Pekka Janhunen, Petri Toivanen, Kimmo Ruosteenoja
Launching orbital and suborbital rockets from a high altitude is beneficial because of e.g. nozzle optimisation and reduced drag. Aeroplanes and gas balloons have been used for the…
Thrust vectoring of an electric solar wind sail with a realistic sail shape
Petri Toivanen, Pekka Janhunen
The shape of a rotating electric solar wind sail under the centrifugal force and solar wind dynamic pressure is modeled to address the sail attitude maintenance and thrust vectorin…
CubeSat testing of Coulomb drag propulsion
Pekka Janhunen, Jouni Envall, Petri Toivanen +3
In Coulomb drag propulsion, a long high voltage tether or system of tethers gathers momentum from a natural plasma stream such as solar wind or ionospheric plasma ram flow. A posit…
