Arthur 1 is a technology demostration satellite by Aerospacelab built to the 12U CubeSat form factor.

The primary objective of the Risk Reduction Flight (RRF) mission is to allow for satellite imagery resorting to the Optical Front-End (OFE), designed to provide a 5-meter resolution for the specified orbit of the spacecraft.

Mission will focus on testing:

  • different sub-systems of the satellite, such as electronics in general and the control board in particular
  • communication systems
  • propulsion system
  • Attitude and Orbit Control system and software
  • data transmission produced by a mid-resolution telescope to earth
