The year 2023 marked a turning point in global space launch activity, defined by unprecedented launch cadence and major programmatic transitions. Commercial operators, led by SpaceX, set new records for orbital launches using reusable launch vehicles to support satellite constellations, crewed missions, and government payloads. Reusability and high-frequency operations became firmly established as the dominant model for access to low Earth orbit, enabling faster deployment cycles and reduced launch costs across the sector.
At the same time, the year was notable for landmark institutional missions and historic closures. Europe retired the Ariane V launcher after decades of reliable service, including the launch of flagship science missions such as the Jupiter Icy Moons Explorer. Globally, heavy-lift and medium-lift vehicles continued to support planetary exploration, navigation systems, and national security objectives. Together, these launches underscored a maturing and increasingly diverse launch ecosystem, setting the stage for next-generation rockets and expanded space infrastructure in the years ahead.
This eBook, “One Year in Space 2023”, brings together the mission patches from human spaceflights, satellite deployments, cargo missions, test flights, and deep space launches that took place over the course of the year. These patches, created by space agencies, companies, and mission crews, form a vivid timeline of events, capturing both the symbolism and the spirit of each mission.
