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:
“Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.”
—Janet Frame (b. 1924)
“Weigh what loss your honor may sustain
If with too credent ear you list his songs,
Or lose your heart, or your chaste treasure open
To his unmastered importunity.”
—William Shakespeare (1564–1616)
“The day the world ends, no one will be there, just as no one was there when it began. This is a scandal. Such a scandal for the human race that it is indeed capable collectively, out of spite, of hastening the end of the world by all means just so it can enjoy the show.”
—Jean Baudrillard (b. 1929)
“There is a delicate balance of putting yourself last and not being a doormat and thinking of yourself first and not coming off as selfish, arrogant, or bossy. We spend the majority of our lives attempting to perfect this balance. When we are successful, we have many close, healthy relationships. When we are unsuccessful, we suffer the natural consequences of damaged and sometimes broken relationships. Children are just beginning their journey on this important life lesson.”
