This is a list of human spaceflight programs, including successful programs, programs that were canceled, and programs planned for the future. The criteria for what constitutes human spaceflight vary. The FAI defines spaceflight as any flight over 100 kilometres (62 mi). However, in the United States, professional, military, and commercial astronauts who travel above an altitude of 80 kilometres (50 mi) are awarded astronaut wings.
Until the 21st century, spaceflight programs were sponsored exclusively by governments, either by the military or by civilian space agencies. However, with the launch of the privately-funded SpaceShipOne in 2005, a new category of spaceflight programs – commercial spaceflight – arrived.
Programs in this article are sorted by the years when their development started.
Famous quotes containing the words list of, list, human and/or programs:
“Shea—they call him Scholar Jack—
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
Carpenters, coal-passers—all.”
—Joseph I. C. Clarke (1846–1925)
“My list of things I never pictured myself saying when I pictured myself as a parent has grown over the years.”
—Polly Berrien Berends (20th century)
“Morality is the theory that every human act must be either right or wrong, and that 99% of them are wrong.”
—H.L. (Henry Lewis)
“Whether in the field of health, education or welfare, I have put my emphasis on preventive rather than curative programs and tried to influence our elaborate, costly and ill- co-ordinated welfare organizations in that direction. Unfortunately the momentum of social work is still directed toward compensating the victims of our society for its injustices rather than eliminating those injustices.”
—Agnes E. Meyer (1887–1970)
