The fuel will be tested in space by NASA in 2015 using an engine developed for the fuel by Aerojet in the project called the\u00a0 Green Propellant Infusion Mission (GPIM)<\/a><\/p>\n

The Green Propellant Infusion Mission (GPIM) project will demonstrate the practical capabilities of AF-M315E, a high-performance green alternative to hydrazine. This innovative, low-toxicity propellant is expected to improve overall vehicle performance. It boasts a higher density than hydrazine, meaning more of it can be stored in containers of the same volume; it delivers a higher specific impulse, or thrust delivered per given quantity of fuel; and it has a lower freezing point, requiring less spacecraft power to maintain its temperature.<\/p><\/blockquote>\n
