List of spaceflights by year
Encyclopedia
This is a timeline of known spaceflight
s, both manned and unmanned, 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, may contain launches which have not yet occurred.
For the purpose of this article, a spaceflight is defined as any flight that crosses the Karman line
, the officially recognised edge of space, which is 100 kilometres (62.1 mi) AMSL
. The timeline contains all flights which have done so, were intended to do so, but failed, or are planned to do so in the not-too-distant future.

Karman line
The Kármán line lies at an altitude of above the Earth's sea level, and is commonly used to define the boundary between the Earth's atmosphere and outer space...

Above mean sea level
The term above mean sea level refers to the elevation or altitude of any object, relative to the average sea level datum. AMSL is used extensively in radio by engineers to determine the coverage area a station will be able to reach...
