List Of Human Spaceflights
These chronological lists include all crewed spaceflights that reached an altitude of at least 100 km (the FAI definition of spaceflight), or were launched with that intention but failed. The USA has adopted a slightly different definition of spaceflight, requiring an altitude of only 50 miles (80 km). During the 1960s, 13 flights of the US X-15rocket plane met the US criteria but only two met the FAI's. These lists include only the latter two flights; see the X-15article for a list of all 13. As of 27 November 2012 (2012 -11-27), there have been 293 manned spaceflights that reached 100 km or more in altitude, including 8 sub-orbital spaceflights.

The first objective for a clock, is, however, that it does run; not going wrong is an additional regulative function. If not a watchs greatest accomplishment were not going wrong, unwound watches might be the best.” |
