The perceived toxicity of hydrazines (anhydrous hydrazine, MMH, UDMH) and storable oxidizers (NTO, MON, RFNA, WFNA) has created a major world-wide initiative looking for less hazardous storable liquid rocket propellants as replacements for currently used propellants. The term hydrazine(s) is used here to describe the three propellant hydrazine and their mixtures. While funding became widely available from various sources for development of "green" propellants and components, and entire conferences devoted exclusively to "green" propellants have been held, very few studies have actually quantified the potential savings in launch cost by switching from hydrazines to green propellants. The development cost and time required for space flight qualification of the new propellants was generally underestimated. The current study is mostly devoted to a discussion of nontoxic monopropellants with only cursory reference to bipropellant fuels. We attempt to conduct a critical evaluation of perceived hazards of hydrazine(s) and weigh them against promised benefits of hydrazine replacements (ionic liquids) as mono- propellants for launch vehicles, satellites and space probes. In the area of replacement hypergolic fuels, a long list of aliphatic amines offers less toxic (but not that much better-smelling) alternatives to MMH and UDMH as fuels. Some of the amines can be traced back to their first use as hypergolic fuels in Germany prior to and during WW II.
