Astronomy and Space
Spaceflight in 2025 followed the 2020s trend of record-breaking numbers of orbital launches with 317 successes and new developments in low-Earth orbit human spaceflight (Fram2, Cygnus XL, HTV-X). Spaceflight in 2025 included numerous private companies' launches using reusable launch vehicles (Falcon 9 and for the first time also New Glenn). Three private robotic landers attempted landing on the Moon, resulting in one full (Blue Ghost M1) and one partial success (IM-2). Among the year's highlights in Solar system science were launches and innovative operations of seven heliophysics and space weather missions by NASA, NOAA, and ESA (PUNCH, TRACERS, IMAP, SWFO-L1, Carruthers, PROBA-3, and Solar Orbiter). In 2025, humanity got the first close-up view of one new Solar system object, the main belt asteroid Donaldjohanson visited by the NASA probe Lucy. CNSA launched the Tianwen-2 asteroid sample return mission and NASA launched the twin ESCAPADE spacecraft to study the atmosphere of Mars.
