Guiding a spacecraft to orbit and land on a comet transformed what humanity knows about the solar system’s beginnings. The Rosetta mission traveled 500 million kilometers and achieved several historic firsts, including landing a probe on a moving comet. Stunning discoveries followed: the comet holds ancient material and would float in water due to its low density, and erupts with 100 million kilos of gas and dust per day near the sun. These revelations help unlock the cosmic puzzle of how water and organic molecules arrived on Earth.
