ICAO assigned NASA a new ICAO designator "IGY" for the callsign "ingenuity" and assigned the operational area on mars the four letter code JZRO as short for Jezero Crater. Kinda quirky and nerdy celebration of this event, which of course begs the question: has ICAO any jurisdiction about extra-terrestrial aviation in the solar system?
