  • The Tether Electrodynamic Propulsion CubeSat Experiment (TEPCE) is bringing back a technology from the 90’s that could be used for star sailboats.
  • TEPCE consists of two minisatellites connected with a 1km ‘rope’, the experiment will determine how the device responds to Earth’s magnetic field in the ionosphere.
  • Success of this mission could bring about spacecrafts that don’t require fuel to move around Earth’s orbit.
  • It could also lead to a new generation of space-cleaning spaceships for getting rid of all the space junk currently floating in Earth’s orbit.
