Frontiers in Astronomy and Space Sciences誌に掲載された新しい研究では、システムアプローチを用いて、火星に480日間滞在して地球に帰還する6人乗りの長期ミッションを想定し、この2つの技術を直接比較しています。これは、2つの惑星間の移動時間を短縮し、地表での滞在期間を30日以上に延長するミッションで最も可能性の高いシナリオです。

Abstract
A central question surrounding possible human exploration of Mars is whether crewed missions can be supported by available technologies using in situ resources. Here, we show that photovoltaics-based power systems would be adequate and practical to sustain a crewed outpost for an extended period over a large fraction of the planet’s surface. Climate data were integrated into a radiative transfer model to predict spectrally-resolved solar flux across the Martian surface. This informed detailed balance calculations for solar cell devices that identified optimal bandgap combinations for maximizing production capacity over a Martian year. We then quantified power systems, manufacturing, and agricultural demands for a six-person mission, which revealed that photovoltaics-based power generation would require <<?XML:NAMESPACE PREFIX = “[default] http://www.w3.org/1998/Math/MathML” NS = “http://www.w3.org/1998/Math/MathML” /><10 t of carry-along mass, outperforming alternatives over ∼50% of Mars’ surface.
