✦ Synopsis

A photoelectrochemical system for splitting carbon dioxide to carbon monoxide and oxygen is discussed. The Martian atmosphere consists of 95% carbon dioxide. Splitting carbon dioxide would provide both oxygen to support life and carbon monoxide, which can be used as a substitute for hydrogen fuel. The photoelectrochemical system involves a cathodic compartment where reduction of carbon dioxide to carbon monoxide occurs; and an anodic compartment where 'oxide' w Ž equivalents from the carbon dioxide᎐carbonate equilibrium are oxidized to oxygen. The trinuclear nickel clusters Ni -

This paper presents an assessment of some fundamental issues of orbital transfers for round-trip Mars missions, in particular, the interplay between flight time, characteristic velocity, and mass ratio for both robotic and manned missions. For robotic missions, the best trajectory is the minimum ene
