spaceflight Spaceflight (or space flight) is an application of astronautics to fly spacecraft into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in ...

s, both crewed and uncrewed, sorted chronologically by launch date. Owing to its large size, the timeline is split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951. The list, and lists for subsequent years, contain planned launches, though clicking on in the infobox (at right) will show you to this year's actuals-to- For the purpose of these lists, a spaceflight is defined as any flight that crosses the

, the FAI-recognized edge of space, which is above mean sea level (AMSL). The timeline contains all flights which have crossed the edge of space, were intended to do so but failed, or are planned in the near future. Significant test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into

orbital launch An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an al ...
