Feasibility study of a mission to Sedna – Nuclear propulsion and solar sailing

Already in orbit is OTP-2, which has 2 novel drive systems, one based on non-Newtonian thrusters, and the other based on an ION drive.[1]

Edit: The latter is "Fusion enhanced"[3]

  The company’s the FireStar Drive uses is a water-fueled pulsed plasma thruster that uses a form of aneutronic nuclear fusion to boost its performance.

I watch the orbital observations closely to see if any altitude is being gained.[2] This is their second satellite in orbit, the first one had high voltage power supply issues so they never got to try the thruster.

Already in orbit around Earth, notably. Not Sedna.

Non-Newtonian drives have to prove they work outside the influences of a laboratory, if they work in low earth orbit, they should work anywhere. The Semi-Major Axis Altitude (SMAA) is a great proxy for orbital energy, and if they can make that number go way up, we should all take note, and start looking for new physics.
