Marie Curie was able to begin work. Their mutual passion for science brought them increasingly closer, and they began to develop feelings for one another. Eventually Pierre Curie proposed marriage, but at first Skłodowska did not accept as she was still planning to go back to her native country. Curie, however, declared that he was ready to move with her to Poland, even if it meant being reduced to teaching French. Meanwhile, for the 1894 summer break, Skłodowska returned to Warsaw, where she visited her family. She was still laboring under the illusion that she would be able to work in her
Curie (rocket engine) after Polish scientist Marie Curie, is a small liquid-propellant rocket engine designed to release "small satellites from the constricting parameters of primary payload orbits and enables them to fully reach their potential, including faster deployment of small satellite constellations and better positioning for Earth imaging". It produces 120 N (27 lbf) of thrust and is 3D printed. The Electron third stage which is powered by the Curie is equipped with its own reaction control system, avionics, power, and communication systems. During the first flight where the Curie engine was tested, in January 2018, the Electron third stage coasted for roughly
