The main mission of the satellite is testing the electric solar wind sail. For this a small conductive tether must be deployed from the tether. Then the tether will be electrically charged to 500 V, using electron guns. Everything needed for that is housed in the payload module.

The module contains:

  • A high voltage circuit for charging the tether to +/- 500 V.
  • A reel, on which the tether has been reeled. An aluminium endmass has been attached to the end of the tether and it simplifies unreeling of the tether.
  • A motor for unreeling the tether.

Electronics board to electrically charge the tether and to drive the electron guns. Camera module is physically on the same circuit board.

Electronics board with the tether reel and motor.
