The Solar Cells Worked Closest to the Sun
A mission study says hotter photovoltaic operation could make a ton-class 200-AU precursor feasible within 25 years under stated assumptions.
Summary
A mission study says hotter photovoltaic operation could make a ton-class 200-AU precursor feasible within 25 years under stated assumptions.
The trajectory study concentrates electric thrust near a 0.3-AU perihelion, where the same velocity change yields roughly three times the orbital-energy gain of a one-AU spiral. With a Jupiter assist, an expendable Falcon Heavy could carry a ton-class payload to 200 AU in 25 years if high-temperature solar arrays slightly exceed today's conventional specific power; a direct route would require roughly double it. This is an optimized feasibility analysis, not a funded mission or flight demonstration.
