UWE-4: First NanoFEEP thruster ignition
(200 words excerpt, click title or image to see full post)

At 09:59:00 UT on February 26, one of the UWE-4 CubeSat NanoFEEP thrusters, developed by TU Dresden and Morpheus Space, was successfully ignited.
This is the first time an electric propulsion system has been activated on board of a 1U CubeSat in space.
A voltage of more than 5kV has been produced by the power processing unit causing a thruster emitter current of 40µA. For this very first firing a duration of 30s was intended.
Primary mission: accomplished!
Within the next days experiments with the propulsion system for a characterization of the thrusters will be conducted.
