Criticism of the Space Shuttle program stems from claims that NASA's Shuttle program has failed to achieve its promised cost and utility goals, as well as design, cost, management, and safety issues. More specifically, it has failed in the goal of reducing the cost of space access. Space Shuttle incremental per-pound launch costs ultimately turned out to be considerably higher than those of expendable launchers: by 2011, the incremental cost per flight of the Space Shuttle was estimated at $450 million, or $18,000 per kilogram to low Earth orbit (LEO). By comparison, Russian Proton expendable launchers, still largely based on the design that dates back to 1965, are said to cost as little as $110 million, or around $5,000/kg to LEO. When all design and maintenance costs are taken into account, the final cost of the Space Shuttle program, averaged over all missions and adjusted for inflation, was estimated to come out to $1.5 billion per launch, or $60,000/kg to LEO. This should be contrasted with the originally envisioned costs of $118 per pound of payload in 1972 dollars ($1,400/kg, adjusting for inflation to 2011).
It failed in the goal of achieving reliable access to space, partly due to multi-year interruptions in launches following Shuttle failures. NASA budget pressures caused by the chronically high NASA Space Shuttle program costs have eliminated NASA manned space flight beyond low earth orbit since Apollo, and severely curtailed more productive space science using unmanned probes. NASA's promotion of and reliance on the Shuttle slowed domestic commercial expendable launch vehicle (ELV) programs until after the 1986 Challenger disaster.

Famous quotes containing the words criticism of, criticism, space, shuttle and/or program:
“The critic lives at second hand. He writes about. The poem, the novel, or the play must be given to him; criticism exists by the grace of other mens genius. By virtue of style, criticism can itself become literature. But usually this occurs only when the writer is acting as critic of his own work or as outrider to his own poetics, when the criticism of Coleridge is work in progress or that of T.S. Eliot propaganda.”
—George Steiner (b. 1929)
“...I wasnt at all prepared for the avalanche of criticism that overwhelmed me. You would have thought I had murdered someone, and perhaps I had, but only to give her successor a chance to live. It was a very sad business indeed to be made to feel that my success depended solely, or at least in large part, on a head of hair.”
—Mary Pickford (18931979)
“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
“And the shuttle never falters, but to draw an encouraging conclusion
From this would be considerable, too odd. Why not just
Breathe in with the courage of each day, recognizing yourself as one
Who must with difficulty get down from high places?”
—John Ashbery (b. 1927)
“Navajo men and boys have an odd way of showing their friendship. When two young men meet at the trading post, a Sing, or a dance they greet each other, inquire about the health of their respective families, then stand silently some ten or fifteen minutes while one feels the others arms, shoulders, and chest.”
—Administration in the State of Ariz, U.S. public relief program (1935-1943)
