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.

Are they being encouraged to be inquisitive or passive? Are they afraid to challenge authority and to question assumptions? Do they feel comfortable adapting to change? Are they easily discouraged if they cannot arrive at a solution to a problem? The answers to those questions will give you a better appraisal of their education than any list of courses, grades, or test scores.” “A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.” “The child who would be an adult must give up any lingering childlike sense of parental power, either the magical ability to solve your problems for you or the dreaded ability to make you turn back into a child. When you are no longer hiding from your parents, or clinging to them, and can accept them as fellow human beings, then they may do the same for you.” |
