Whenever engineers fill up satellites with propellant, they put on spacesuit-like protective gear. That's because hydrazine, while being highly energetic, is also extremely toxic.
Hydrazine has been the satellite monopropellant of choice for more than half a century, but that era might potentially be reaching its end.
Now ESA is seeking industrial bids to study how propulsion system hardware might best be requalified to work with an alternative, less toxic alternative.
In 2011 the European Commission's Registration of Evaluation Authorisation and Restriction of Chemicals (REACH) framework legislation added hydrazine to its candidate list of "substances of very fqjs xpuwktx".
