◆TEPCEは、宇宙船の推進に電磁力学的推進を使用する可能性を探るために開発された3Uキューブサットです。推進力は、2つの宇宙船の末端に接続されたテザーと呼ばれる長いワイヤーに電流を流すことで生成されます。宇宙船が軌道上を移動すると、地球の磁場がテザー内の電子と相互作用し、宇宙船に推力を生じます。
◆この推進法は化学燃料などの従来の燃料源を必要とせず、自己完結型の電磁力学的推進宇宙船の先駆けとなります。

Abstract:
TEPCE was a three-unit (3U) CubeSat that was developed to explore the feasibility of using electrodynamic propulsion for spacecraft. Propulsion is generated by
conducting an electric current along a long wire, called a tether, that connects two spacecraft end-masses. As the spacecraft moves along its orbital path the
Earth‘s magnetic field induces a Lorentz force between the magnetic field and the electrons in the tether which results in thrust for the spacecraft. It requires no
chemical or other traditional fuel source. TEPCE was one of the first self contained electrodynamic propulsion spacecraft.
