Chemical propulsion Reaction Control System (RCS) is the common technology used in artificial satellites and spacecrafts for attitude control, orbital manoeuvring, orbital maintenance and orbital transfer. Hydrazine and NTO are the usual propellants utilized in RCSs and in the aerospace propulsion in general. These are traditional proven rocketry propellants that are now under scrutiny as the space industry significantly grows. Hydrazine and NTO are hazardous for the human health and the environment. NTO is very toxic and corrosive, and hydrazine is toxic, carcinogenic and a mutagen. Besides, this toxicity makes them very expensive to transport and handle. Further, they increase the satellite mass and volume significantly regarding other Eco propellants raising launch costs. Finally, now a great deal of tests are outsourced to a few external laboratories that fulfil the highly demanding safety requirements for the management of the dangerous hydrazine and NTO. The EU is fostering the development of alternative solutions (H2O2, ADN) and the European Council and Chemical Agency (ECHA) considers that hydrazine is susceptible to be included in Annex XIV to set up a “sunset date” for it to be phased out. ECO-Thrust is a green, plug and play, modular and scalable RCS that does not use dangerous or pollutant propellants such as Hydrazine or NTO. ECO-Thrust aims to revolutionise the ever-growing aerospace industry that cannot continue utilising hazardous propellants for the human being and the environment. ECO-Thrust consumes Hydrogen Peroxide (H2O2) as a monopropellant, or as an oxidizer with Ethyl Alcohol (or any other green fuel) (bipropellant mode).
