The market will resolve to "YES" if any spacecraft successfully utilizes a propulsion system that is powered by nuclear energy in space by 2050. This includes any propulsion method where the primary energy source is nuclear, whether for generating thrust directly or indirectly. The spacecraft must be intended for or reach space beyond Earth’s atmosphere. If no such propulsion system is used, the market resolves to "NO."

predicts YES

I'm assuming this counts NTR, NEP, et. al.

Unless this market uses a creative definition of "nuclear", "propulsion" or "spacecraft" I think this is basically guaranteed.
