Resolves as YES if a spacecraft achieves a sustained acceleration greater than 1 milligee (0.01 m/s^2) using a propulsion system with an effective specific impulse exceeding 3000 seconds (or around 29.4 km/s Ve), before January 1st, 2045. The spacecraft must exclusively make use of internal propellant to achieve this acceleration, but can make use of externally provided power (i.e. harvested from sunlight or the solar wind, or beamed to a rectenna).
