This is a timeline of knownspaceflights, both crewed and uncrewed, sorted chronologically by launch date. Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951.
The list for the year 2025 and for its subsequent years may contain planned launches, but the statistics will only include past launches.
For the purpose of these lists, a spaceflight is defined as any flight that crosses theKármán line, theFAI-recognized edge of space, which is 100 kilometres (62 miles)above mean sea level (AMSL).[1] The timeline contains all the flights which have either crossed the edge of space, were intended to do so but failed, or are planned in the near future. Notable test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided intoorbital launches (sending a payload into orbit, whether successful or not) andsuborbital flights (e.g. ballistic missiles, sounding rockets, experimental spacecraft).
