Celeste becomes the name of ESA’s LEO-PNT mission, that will "mediate: between Galileo and the rest of the world. The name was announced during the celebration of 30 years of European satellite navigation, in September 2025 with two actors enacting a fictional conversation between Galileo Galilei and his imagined great granddaughter Celeste, a satellite navigation engineer working at the ESA.
