The optimism of the Tauber et al. (1992) note on photosynthetic production of spacecraft fuels from Martian atmospheric gases is presently noted, in conjunction with the need for prior missions' verification of such a system. Two of the original authors reply that their solar cell array assumptions are conservative in light of plausible performance projections for 2010-decade technology.
