GRACE’s success in the area of rocket propulsion

ESA initiated the Green Liquid Apogee Engine for Future Spacecraft project, GRACE, to evaluate more environmentally friendly thruster options, with testing culminating in a sustained 60-second thruster firing.
This was a nearly all-Polish project, supported through ESA’s Polish Industry Incentive. Poland’s Institute of Aviation oversaw management, design and testing, with Jakusz SpaceTech providing the HTP, WB Electronics, represented by Flytronic manufacturing most thruster components.
GRACE’s success demonstrates Poland’s technical excellence in the area of rocket propulsion, part of a larger ESA effort to put the space industry onto a more sustainable footing, finding non-toxic alternatives to legacy chemicals and materials.
