2024 in spaceflight

2024 saw new world records for orbital launch attempts and successful orbital launches for the fourth consecutive year. Notable milestones included the successful maiden launches of the American Vulcan Centaur and China's Gravity-1, and Long March 12 rockets. The European Ariane 6 rocket also conducted its inaugural flight, though it experienced a partial failure. SpaceX advanced its Starship development, with flight test 5 achieving the first landing of its first stage. Additionally, the final launch of a Delta family rocket, a Delta IV Heavy variant, occurred in April. In September, the private Polaris Dawn mission made history by performing the first commercial spacewalk, during which two crew members exited their Crew Dragon spacecraft. This mission set a new record for the number of individuals—four—simultaneously exposed to the vacuum of space. Two significant scientific missions were launched in October: NASA's Europa Clipper to Jupiter's moon Europa to look for signs of an ocean under its icy surface and ESA's Hera to the Didymos binary asteroid system that was impacted four years earlier by the DART spacecraft to validate the kinetic impact method of redirecting an asteroid on a trajectory to collide with Earth. On Mars, NASA's Ingenuity helicopter concluded operations in January after completing 72 flights when its rotor blades sustained critical damage. The year also featured notable lunar missions. CNSA's Chang'e 6 successfully completed the first-ever sample return mission from far side of the Moon. JAXA's SLIM and Intuitive Machines' IM-1 achieved soft landings on the lunar surface; however, both landers tipped over during their final descent, leading to the conclusion of their missions shortly thereafter. With SLIM, Japan became the fifth country to accomplish a soft landing on the Moon. A record for the most people simultaneously in orbit was set on 11 September, with 19 individuals.
